0:45 use their description and exercise question while applying any concepts or techniques discussed in this video Video Hello Everyone This is Chaitanyaswar Prasad Indian Book of Records Holder and Certified Ethical Hacker OK Guys, again, many people are confused. The main thing is to learn to hang. Where to start when a problem arises? I don't even know what to do, for our Telugu people. Ethical Hacking Course Released in Telugu Guys, what are you doing here? Can do means the whole course You can learn by taking this course. What happens is that you automatically get cyberbullying. How to start a career in security Not only that, but advancement is also required. How are you doing in cybersecurity? There are domains, but how? How to become a better hacker You will know all this too. That said, I have a lot to say about myself. In cybersecurity related startups I worked hard, guys, even though I am a B.A. Graduated guys, besides that, I have this Seventh in Cyber Security There is a lot of interest from the class. So with that interest I entered tenth grade.

1:31 I started working in microsoft paypal nokia lenovo similar Only in very, very large companies I hacked and got the rewards. So now we are going directly to the course. Let's get to the content, guys and one. More things to go to course content First you have to do one thing. Subscribe to the YouTube channel. If you haven't, go and subscribe quickly. Do it guys because we have Informative cybersecurity content It is provided regularly. We will be there, and our Instagram channel Also check it out and follow me. So that's it guys, let's go now. What is Direct with Call Hacking? So first of all let's discuss the content. Let's see what we have here. Guys, that's what cyber security is. What are we really saying here? Discuss what is cyber security. We will do it, and you can watch Next. What are careers like in cybersecurity? What can you see in real careers? Then comes the differences between Ethical Hang and Cyber Security The real ethical hacking and cyber Is security the same or different?

2:16 That's all there is to it, a clarification is coming. Apart from that, cyberkills and methodology means Let's find out what CI Trade is. Very important concept to say. That's what cyber security is about. We are also going to find out, guys, besides that. How many in the next ethical hacking There are phases, followed by types. Networking of hackers We will also set up a lab, so to speak. Guys, what's going on in the lab setup? Actually we are directly hacking. It says it can't be done on all servers. For that we will do a lab setup. We will continue to gather information about it. We will scan the network later. Next Web Server Hacking Windows Hacking Android Mobile Hacking What is DOS? What is DDOS? What is snipping and all that? We will find out, so along with that, social We are very fond of engineering. Ayan location tracking webcam Hacking Phishing Malware WiFi Hacking cryptography is all about this. Guys, we are going to learn the concepts too. Let's start straight away. So what is ethical for many of us?

3:05 I want to get a job as a hacker. Simply put, this means cyber. Want to start a career in security? But the main problem is that we have to There is no certain guidance on what roles will be available. What are their responsibilities? Where to start and how to end? No one understands what to do, guys, okay? Let's talk about it now. So first of all, let's discuss. We put cybersecurity first. Let's find out what cyber means. Security is the practice of Protecting Systems Networks and Programs from Digital Attacks This Attacks are usually emitted to Accessing Changing Destroying Sensitive information except money From uses we ramsom where are Interrupting Normal Business Process Okay, fine, so if we look here, we have The definition is a bit confusing. Whoever is listening now will be new. Because here we mean transform ware What do they not know about all this? Let's put it simply in our language. So now we are well on the internet. Guys, we're addicted to online. We also get money from shopping. We need to transfer out.

3:52 No need to go to RL Bank. No need to go, everything is also internet. If we say that we are dependent on The problem here is that it's so digital. We are going to our world with advantages. Are there any disadvantages to using us? There are also but coming to the cyber Security: How does this work? What is cyber? Guys, actually cyber. This is nothing but the virtual. World means digital world. Simply put, what are we all? Even a phone can live in it for a year. Otherwise, we can't stay away from the old people. Everyone, even children, has access to the internet. Utilizing it, but here is a big The problem is that our data is what we Let's transfer, guys. Whoever these illegal hackers are through the internet They stole our data. Either sell it or lose our reputation. They either look to lose it, so for that This cyber security is introduced What is cyber, what is digital? What is world security? This is what seems to protect this digital world.

4:38 Cyber security is a word that many people There may be doubts about who is an ethical hacker in cyberspace. Security Professionals Who Are Guys? Actually, cyber security is a big If you mean domain, then this cyber security There are ethical hackers down there, okay? Cyber Security Ethical Hackers Are Different No different guys in cyber security Ethical hacking is a part of Okay so don't worry, many people are ethical. Hacker is different from cyber security. It's not that they think the two are the same. So let's come to the main now. The big question is, everyone should stop their career. When this question comes up, Coding in Cyber Security Out of Fear Guys, if you ask me, is coding necessary? It's not mandatory, but it's okay if you learn coding. You can do it even more advanced. That's all, what else is there to code? No, there are also rolls without coding. So what are they like in cyber security? How to do it bro starting point What is the meaning of the ending point? Let's talk about cybersecurity anytime

5:24 If you want to enter, we have these two. Networking is something that should have come from the side. And what are we really going to do if these two things don't come? If it's not possible, this network Why is Linux so good at networking? Important means, so anytime is fine. This is how the internet travels When we learn networking, You know, guys, how does it travel? What happens is Linux. Why should we always utilize OK? Our hacking skills We need to increase our own operating If you want a system, you need Linux. These two difficulties are so difficult that you must have learned them. It's not difficult guys, it's very easy, okay so Next one is the types of hawkers Hawkers Let's See Who Are These Hawkers? What do you think of hackers, actually? We are all three types of hackers. It's something we should keep talking about. When Coming to the Cyber This is a security black hat hacker. Who is an illegal hacker? Simply put, I do bad things.

6:09 There is a grey hat hacker, who is this? Show me. Think of it as a hacker, it's simple. In other words, what he does is bad. Otherwise, it doesn't harm anyone. Simply put, on friends. facebook hacking prank or something What can we do by hacking Instagram? Are you harming your friend, Miss You? Are you doing it or not? Just for fun. We are doing it, so we are the ones who are grey. We call them hot hawkers because of them. There is no harm in having fun. They keep saying and coming to the White Attacker What does this white attacker do? Totally Legal Guys, These Are Actually Ours From government organizations Our systems range from private organizations to I will secure either you or everyone. To put it simply, there will be. What do we call white hat hackers? We call them ethical. Hawkers say okay let's go here. We have an offensive next time. Security is also called defensive security. There are types of guys in cyber security. What is offensive security anyway?

6:54 We are the red team, we are normal. Defensive security is the blue team. If we say so, then this red team is blue. What's the difference between a team and a bro? Guys here. You should understand the offensive in the names themselves. What is defensive and offensive warfare? What does it mean to be defensive? Saving is now as simple as a For example, we have our army. Border guard system No one can enter without saying that it is there. Otherwise, forensics after coming in There are many investigators. What will they all do? Investigate and use It's simple to say they'll catch you. Whom to enter inside, so to speak? This defensive is making sure it doesn't happen. But when they come to the offensive What are they, direct war? Guys, go inside and attack. First, they say they will start doing it. They will eliminate anyone who wants to come. What happened to anyone who was defensive? They know what to do next. How to catch someone who says "it's okay" So we should use it when coming to

7:39 The same goes for cyber security, guys. What happens in offensive security? First, what do they do on the systems? They are attacking the servers. Then they will secure it. What's next? What do the defensive guys do? Okay, that's it. Someone who thinks they are secure New hacker uses new techniques So then you can come in. What happens is that this blue team is ready. I wonder if anyone will come in. You see, this is how it happens and I know. There will be a lot of confusion when it comes to To this offensive security and Defensive Security Don't Worry Guys You will understand all this slowly. Watch the full video, so let's see. Now let's talk about cybersecurity. Roadmap for beginners is okay. How to learn cybersecurity for beginners What domain should I go from and how? Where to start? I don't know how to end it, so here it is. If you look at us, I'm just starting out. I told you about networking and Linux. But that's the foundation point guys.

8:25 So what can you do without learning? You can easily learn the foundations. Networking and Linux is so It's not that difficult, okay, so I learned it. Then they will learn ethical hacking. Guys, you are into ethical hacking. What happens is we are sniffing. What is ransomware and social engineering? Let's learn about such topics, okay? What most people think of ethical hacking When we learn, they think we are a piece of cake. But not guys because it's ethical. Your original after hacking is done This is where your career starts. You can see three types of bug bounty below. Hunter VI PT SOC OK here Who is a Bug Bounty Hunter and why is he a freelancer? Okay, he works from home. VI BT says he won't work for the company VBT Who is Vulnerability Assessment and If we call it penetration testing What are these VIPs actually doing? If you want to do it, go to the organization. What are offensive side guys? We talked about them attacking, didn't we? They will attack and tell them.

9:12 You have this weakness here, okay, you cover it. What are these SOC people saying? If you do it, I'll tell you more. Someone is coming in to be defensive. Hacked After being hacked How to plan what to do next This is all about how to catch them. So it depends on the shock. You should watch something in the mood. Guys bug bounty hunting vi bt if this Which of the three can I choose? Bro, you can ask a question, but it's It depends, now look at the bug. Bounty hunting is simple for you. What are they going to do now? I will take a company even if it is me. Microsoft could be Nokia could be PayPal Anything can happen, anything can happen, what will I do? That means they will hack their system. After the hack, I told them It's okay if you say you'll report it. You've been hacked, so cover up. So what do you do to us? Tank means certain bounties to us. Simply put, it's a reward.

9:58 So they will pay us a certain amount of money for a buck. Okay, you worked hard and hacked our company. Thank you for reporting it to us. They say, "So the next one is the one." So VA PT Vulnerability Assessment and Penetration testing this vulnerability What will be done in the assessment is a certain Use tools and perform automatic scans What does it mean to do most of this? There is no work for us, what can one do in this? Our website is where you can get the tool. They will automatically click on scan. That's what brings all the weaknesses together and makes a It's fine to say that you'll give a report, but... Not so in penetration testing. Guys, this is totally different, what's wrong with this? If we do, we will test manually. What you need to do is use tools like Bubstit. Use it and test it manually. We will then generate a report on it. So that's the difference between the Vulnerability Assessment and Penetration Test So Let's Discuss About The Sack What are these Security Operations Center people? If you do it, simple guys are always okay.

10:44 Anyone is entering our home. A hacker tries to hack It's okay if he's doing it or if he's hacking. What to do next is up to them. What if the word "know" is being entered? They do it, they try to stop it, that's all. What if, after entering, They will try to catch you. The shock of what they are doing is actually this. We are at the beginner stage now, aren't we? Bro, now let's set these three. You still haven't got clarity on how. Simple Guys You Mean Bug Bounty Hunting Sitting at home under a freelancer If you want to do bug bounty hunting or something What do you mean by certain testing now? If you have an idea about some web technologies Vulnerability Assessment and Penetration Is it a testing sack? What else is a sack? Totally related to networking Guys, if you are good at networking, this So you might be in for a shock. Not only that, this is about beginners. Okay, fine, now that we understand. Cyber Security Roadmap for You understand what a beginner is here. See Networking and Linux First.

11:29 Ethical hacking is something you should learn later. Our original career started from here. Bug Mounty Enters Avudama Vi BD It's a matter of whether we go or go into the sack. Okay guys, you are now VI BD. I'm fine, I'm fine, everything is fine. I'll be a beginner, but I'll be my own. How to advance in your career How can I increase my salary after going to the company? So don't worry guys, we're in this together. It means you can continue to grow your career. We can also discuss how that works. Let's do it, let's do cyber security. Road map for What happens in this with intermediaries? That means first of all bug mounty hunters So let's talk about Web Bounty. Hunting is a web activity for many people. Start working on applications But there is a big problem here. What is the start on the web application? What if I have more competition? You may encounter the problem of not finding the bucks. However, you can use the Android application Testing should start as well.

12:16 As an API cloud, we are freelancers. Guys, you can test all of these below. You can test this independently. This is how we start a bug hunting career. That's all it takes to make an advance. Apart from VI PT Vulnerability Assessment And penetration testing here So what's the web here? Application pen testing we We will do it at the starting point anytime. Okay, so how do you advance it? Android application because it should be done What do the pen testing guys do here? There are Android applications, look at us. facebook instagram like these you Should I hack and report it or not? Do you want to secure direct? iOS app pain testing is done We thought of a simple Android app here. Here ios means simply Can apps be read on Apple phones? Applications can also be tested. That's all, here is the api What is Penetration Testing in AP? AP Penetration Testing in progress How to pen test APS iot iot You know guys, the Internet of Things.

13:02 So how is it called a pen test? That's all about how to hack and report it. What is automated pen testing? What's up with the car hacking guys, okay so car? What do you do in hacking? Hack a car. We will report it and wireless. What is Pen Testing Wireless Networks? Simply put, WiFi hacking No Guys Wireless Pen Testing Means Telecommunication from Bluetooth What happens to us all wirelessly until How do we hack it and report it? This is after testing this wireless pen. That infrastructure pen testing Guys, what this means is that you are totally on fire. Privacy escalations from Vas Everything up to the infrastructure pen What happens in testing is a hole. They say they will secure the organization. Next one is the cloud pen testing What happens in cloud pen testing? We are pen testing for the cloud. We will do it, besides the network pen Testing Guys Network Pen Testing What happens in the world is now up to us. Certain protocols may have all of these. Either old, outdated protocols or This means that you are using outdated versions.

13:48 We are in this network pen testing So guys, let's find out. C But the big doubt here is that here Android app is undergoing pain testing Isn't this only from the start? It's not that only those who have learned should go. Guys, imagine you are an application developer. Directly to the pain test field If it can't come, you have a grip on it. Now it's up to the iOS developer to decide. IAS pen testing is very easy. When Coming to the Cloud Cloud Administrators, that cloud pen for them. It depends on whether testing is still easy. So directly we are cyber Learning security from scratch There's nothing to come, okay, you're already ready for this. If you have knowledge, you can directly You can also learn pen testing. Next one is the sack, guys. It is very difficult to define a sack because We have three types in our bag. For many people, this is their starting career. They'll see what they're doing here. What they don't do is a small tool. They say that the word used is Currider.

14:33 Or something like that, like Splunk. Anyone can use those tools If a hacker is coming to attack They get notifications there. We say alerts, we lock it. What did they do after checking all those locks? They will report l2 It's okay for them if this is an L1 word, but in L2 What happens is that guys compare to l1 l2 are slightly advanced and Also known as Incident Responders What would they do if it was an incident? How to respond when that happens? What are the next steps to take? Not only that, but also report to l3 It's okay to say that they are doing it, but what are they doing? They do more than these. Advanced guys, it's simple. In other words, they are malware analysis. From reverse engineering to What does it mean to say that everything will come? Guys, you can easily get rid of the virus. They are hackers no matter what they appear to be. Simply put, to enter means You can do l1 then l2 then l2 then l3 It means that those who can do it can reach these levels. Shocked by That's It Guys and Next One

15:22 Is the application security engineer okay? Let's discuss about this engineer. What happens here is this application guys What happens in a security engineer role? You will see many developers. Software Developer Life Cycle They say there is only one thing to say. But this application is like that. What security engineers do is code Is that correct? Fine, but security? Is everything working fine for the code? They'll be watching you as well. It also means that they implement AS. They say they can fix it, that's all. Apart from that, they have strategies. How to make the application more secure This application can also do Security engineers will take care of it. Simply put, they are developers. To put it simply, come on hawkers I said coding is required here, right? Sometimes we need coding a lot. What can't we do without coding here? So the next one is the one Sast vs. Dash but this Sast What does vs. dash mean? People get confused but static

16:08 Analysis Security Testing Antam Dash That is, dynamic analysis security If we say testing, look here, white. What is box security testing? They give us information, guys. Test us by giving information in Sash. What do you mean by "what server are you on?" Test should be done, code will be given, everything will be given. What is the process like for a developer? Indaka works as a developer in Sash. I told you, application security. What are the requirements for being an engineer? That is, the source code is the source code. They said they would give it to them, but they didn't. They give you a code and ask you to test it. Okay. You see, they test the code. hdlc software development life cycle How it works is earlier. Stages Guys is what we do in advance. You can find them all. Also, if you look at the cost of fixing here What does less expensive mean? If the work is done at the rate, then the run time Why can't they find the issues? It is not an already running application. They're already ready before the guys start running. It means discovering.

16:53 Vulnerabilities are okay, that's it guys. This is how issues are discovered when Coming to the Dash Dash see Black What is Box Security Testing? What happens is totally up to him. Guys, they don't give information directly. What website does the person use to look at his face? You get the information yourself. Gather information, everything. It's simple to say, "Do it yourself." How does this person think, so to speak? Guys, think like a hacker. Did you also provide the requirement source? So far, we have developers here. No, what about the running application? This guy has to take it all. This is something you have to explore. Software Development Life Cycle This is the next stage after it's over. All is over, product release. R Els application release is over. It's over, they'll do it later. Why is it more expensive than before? What did we do sitting down with the developer? Not like that here, you have to use tools. Some people need to be hired for testing. That's all there is to it. There's a lot of work to be done. It finds runtime issues instead. Can you guys do it this way?

17:39 Dash work out is static. Analysis, simply put, is Reviewing code is Dash Dynamic Analysis means no coding required What does Bubs Suit do directly? Test using tools like these He says, "That's the difference." Between taste and taste so let's Discuss about the Security Architect Okay, this architect is simple, guys. You will see designers in civil. What do they do to keep the building neat? How to construct what to stay What needs to be done is what is designed. So what is a security architect? How do we do it in our company? Network security is simple. Implement cybersecurity, so to speak How to plan and how to do it How to develop policies How many employees should be hired? Also this security architect It's a lot to say that he takes care of it. These are experienced persons. So next one is the auditors and Who are the Implementers Auditors? Actually, we are financial auditors.

18:25 We will hear about CA, but here Not like that, guys, who are the auditors here? What do they do under the implementer? Look, is there an implementer? What is this guy? It means "I will implement it." Establishes policy standards That means he does maintenance. Standards are all standards. You may be wondering what that means, bro. Don't worry guys I'm all Let me explain this. Implementer, whatever it is, establish all Be careful what you maintain. It's okay to say that auditing is the auditor's job. Are all the companies doing well? Is everything running according to policies? Besides, what are the auditors like first? Party Audit Second Party Third Party There are three types of audit, so these are They can also see three types. What does that mean, sir? The company can do it on behalf of the company. You can do it for another company too, okay, so many people There will be auditors, don't worry guys. There will be confusion, but don't worry. What do these implementers do?

19:11 Look, Anna, they have standards. So, they say there will be frameworks. Let's discuss them in detail. You can watch Guys Actually Cyber here. Security Standards and Framework There is a lot of confusion about what works means. Yes bro, I've heard this many times. But what we don't know is... Simply put, guys. Cyber security at any time The organization needs to run, which means certain cyber Security Standards and Framework This framework should work as standards. Bro is the guy who is listening to everything new. You all will be graduates too. About OK R SMIC University It's simple now, you know. In other words, my college is my university. One is that many people here have done B.Tech. So let's learn about B.Tech. If you say that JNTU is very famous, Any normal college name Bring it, okay, Nalla Narasimha Reddy. Something is affiliated with something. Bye JNTU, you guys too. Only JNTU rules should be announced. Otherwise, take a bank, college.

19:57 Leave it in the bank, what bank is it? Okay, he should shut up and go to RBI. What does it mean to do what you are told, RBI? Standards and Frameworks Everyone in the bank follows. We are doing the same thing. We thought colleges would see one The university is top level. The university is more in our Hyderabad. University to Osmania University Even I am now in flight. The college I studied at was also Osmania. What does it mean to be a flight away from university? Osmania University put it up. We should use exam papers, they say. We have to follow the rules that have been laid down. So the bank also has to do this. Do what the RBI says. Also, what is happening now in terms of cyber security? I will establish a company. I did it guys, but what about my company? Everyone came directly to the product. Ivar Okena is an application or a client. Come here, you take it. There is no such thing as an application, there is no real cyber. How much security is there in your country? I'll tell you something. ISO adopts standard framework So it's okay to say that I'll take the ISO and tell you.

20:44 Ours is ISO 27001 standards and We are using frameworks. If you say that, then he will gain trust. They say show me the certificate, okay? We'll show you, fine, okay, done. Why is ISO a project? Simply put, our security They said that all the systems are fine. That is what the standards and If you are using frameworks This is not ISO, guys, PCI DSS. See this: Payment card industry And data security systems What is going on in this bank RBI? All of these are PCI DSS. Used means each one individually. Guys, if it's work, then I'll do it. As stated by the implementers auditors I said yes, but this ISO Let's take this ISO as an example. Follow standards and frameworks What to do is ISO 27001 The implementer comes after saying policies. All the regularities have been done. He establishes. Maintains the same way as Next The auditor will come and check, that's what ISO says.

21:31 27 001 Guidelines All of them are correct. Are you following me correctly? They check, so this is the difference. Between the Auditor and Implementer However, this includes cybersecurity. Many in Standards and Frameworks Some kind of framework until They put it on, and some Organizations are more than one thing. Don't be confused by the word "putting on". Guys because this is totally a bit Advanced career so you have a little You might get confused, so don't worry. It Chief Information Security Officer But this Chief Information Security Who is the officer? What is Nayana? He is the whole person. Put on a suit and get a little hyped up. Don't think I'm giving too much. No matter what you do in the organization, this CISO No matter how much you want to report, Are you a hacker or something? Who are you working under, guys? What is a Chief Information Security Officer? What do you mean he's executive level? That means now CEOs are CTOs and CFOs.

22:17 Will they all be with them? He sits down and discusses with the CEO. The CEO takes care of all the operations. When Coming to This Chief Information What does a security officer seesaw do? Operations at security level He says he will take care of it and this is the seesaw level. What do we need to do to go to the minimum of 15? Years of experience are expected. They say they will do it and it's that easy. It doesn't come easy, guys, this is very Standards mean total intu management This is the side of the work that Sisow does. Simply put, everything is under the seesaw. You hackers work alone. Hire Application Engineers Take architectures, everyone. They say they will be under them, so the next one Exactly, we are senior level. Management Mid-level Management What exactly happens at the entry level? So let's find out who's in it. Everyone here is in entry-level jobs. So what does it mean to enter? Ethical hackers have penetration Testers will be security analysts. So what did I say, look at this?

23:04 They are the forensic experts. What is a vulnerability assessor? Vulnerability assessor There will be incident responders. They are all security consultants. What is entry level? You are direct. Apply for one of these jobs. Next one is the middle. What happens at the mid-level level? This is where Annamata Architectures reside. There will be security engineers, so we We thought, look, coding should come. Application Security Engineers They are incident responders here. There will also be security auditors. We thought so far, implementers. That's what policy positions are all about. Implement all of them also policy Guys, positions will come down. The main problem here is the mid-level If you want to come to me, you can send me the skill directly. There is more, I will do mid-level. That means they won't take you first of all. Even if it takes two to three years at the entry level Must have worked and then mid-level You can see above after that. Security Directors Security Managers, Deputy CISOs, all of them. You have a minimum of 10 years of direct experience.

23:49 Experience is expected. The guys are very expert. It should be over, so after that you will have this There are positions so the next one is the Job roles are the main thing here. The problem is that even at the entry level For intermediate levels or something People don't understand, even on LinkedIn. What kind of job do you actually look for in Naukria? What titles should I apply for, bro? What is so new about all this? The actual organization is going crazy. What do you mean by don't understand? Worry Guys First Engineering Purpose Let's see digital infrastructure Security system creation What is Implementation and Maintenance? First of all, this guy needs to learn coding. Okay, let's make it with coding. There must be a capability to implement. That is, to put it simply, security. Implementation guys are that product. Is everything going well? Anything else? Can firewalls be implemented or not? Can I install it? All of this is included. To put it simply, What do security engineers do? Infrastructure Security as Well

24:35 AS System Creation Implementation And they take care of maintenance, so... What are their job titles? Application security as expected An engineer can be a security engineer. Maybe if he was an engineer in terms of cloud If you want to become a cloud security engineer Maybe if there is a sharp in the network So you could say network security engineer. These four job titles are always good. Remember when it appears It is related to the engineer and they Definitely coding software They work in the development life cycle. So the next one is the one that has to be done. What is testing testing actually? Don't go away about cue testing, guys. Let's look at the different purposes of this first. System Application and Network Evolution for Potential Security What do they do to the vulnerable? The engineers saw it as expected, didn't they? What is their software development life? Worked on the bicycle after completion The Software Development Life Cycle Product application released It has been released to the public. They say they will start here.

25:22 What do testers do with that product? Whether to test or hack or not Not only do they report, but they also An audit is being conducted here, which means an audit. Only implementation as we intended. No, guys, scanning the network is not working. Scanning using Else Necessities Doing a vulnerability assessment includes all of these. What do they actually fall under? Auditings will come down, okay, but here. What we are doing is a certain application. Technically, we are auditing. Skills Required Guys Apart from that You can watch the roll here Penetration Testers call it vulnerability assessment. It is also called vulnerability assessment. And penetration testers are called Auditors are called web application auditors. Security auditors like all auditors So come down and analyze what's going on. Annamata Next One is the Analysis What do these guys do, analysis guys? It's simple to predict what In other words, it's a matter of estimating once or not. They will monitor and see if there is any inequality. See their work here. Purpose Let's look at the data system and pattern. Examination to Understand and

26:08 Mitigate cyber threats with data A system can be a pattern, a They all have an examination pattern. Why do you keep checking cyber? So who is in this to stop the threats? What does it mean to be a cyber security analyst? We thought that means he is a sports analyst. They will fall under this before us. Threat Intelligence Analyst Security Operation Center Analyst Level One They will come down to the level below. Jobs are available only below level three. You decide this based on the description. What you need to do is become an intrusion analyst. These guys are just level two down. They will come, okay, fine, so let's analyze it like this. So the next one is the response. Guys, what's going on in this response? Many hackers have arrived. Hackers. Someone came and hacked the systems. What does it mean to take over? The breach is over, but what do we do after that? The response team will see if it can be done. So what's the incident here? What does the respondent do? A hacker. How can you respond when someone comes and hacks you? What are the next steps to be taken? Next one says he'll take care of it right away. This is a cyber security incident.

26:54 The manager does that, that's all he does. What does a forensic analyst do? He tries to catch the hacker. What does forensics mean? What does he do? He hacked. Are there any locks? The next one says he will take care of them all. What happens in auditing? IT Systems and Operation Evolution for Regularity Compliance and Best Simply put, process is Take GRC, it's called guys' governance. Some call it risk or compliance. However, under those domains, they are Cyber security auditors say they will come IT Compliance Auditor Security What is a control assessor, guys? Actually, all three of them are the same. Okay, but the names are different. Here are the job titles: You can apply when it appears. Don't worry guys, this is all confusing. Don't be afraid when it comes to engineering. You can see the security engineer security. Engineer Cloud Security Engineer Network Security Engineer Coming to Testing Penetration Testers Vulnerability Assessor Vulnerability Assessment and Penetration Testers Security Auditors Analysis Analysis

27:41 SAC Analyst Antam Security Analyst We are a cyber security analyst threat. Intelligence Analyst Intrusion Analyst Incident Managers in Antham Response Security Incident Responders Forensic Forensic Analyst RS Digital Forensic Expert All of this is included in auditing. Let's look at cybersecurity in auditing. Auditor IT Compliance Auditor GR Auditor ISO 27001 Auditor Similar There are ISMS auditors. PIMs will always come as auditors. They all come to the auditing side too. Okay guys, that's the cyber security job. Titles are like this, so cyber Security working in an organization These are the job roles. Responsibilities Their network is this network. So guys it is a collection of inter Connected computers and devices that Can communicate and share resources So I know that if you look at this definition

28:26 So let's take a look at what you don't understand. Real time example guys so here If you look, there is a Chaitanya network. Chaitanya's network is nothing but his Let's say it's a house. Okay, what's in his house? There is a router, there is a computer, there is a A laptop and a printer and as well Yes One Mobile So all this is one This computer can be a group of devices. RS can become a laptop RS It could be a printer, it could be a mobile, all of these. What is also connected to the router? Connected so connected to router Because of becoming, all of these things are one with each other. So here you are, able to communicate. Maybe a little more depth, maybe a little more confusion. Let's go, guys, you can see it here. When I was giving a time example, I had a There is a printer so I am on that printer. I want to take a printout from the butt. It says it has a wireless connection. Then what, I'm using my laptop here. Can I use the phone? Suppose I used a photo on my laptop. What happens when I press print? Printing on a wireless printer

29:11 It starts guys and here is a Doubts may come to our laptop and our The printer doesn't even have a connection, right? What is wireless, not a wired connection? It worked, why did it work? I already printed it because Guys, it's associated with the router now. We can use the laptop here with WiFi. Connected to mobile, maybe with WiFi. Our printer is also connected. Maybe it's connected to WiFi. What will happen because of that? Actually, a Communication from one device to another It happens so this is what we network. Hey guys, now I have this definition for you. Understandable, see the collection of inter Connected computers are computers What are the internals and devices too? They are all communicating together. Are you sharing resources? Are you doing Resources is Nothing? But does the data share data? Now we all know what it means to look after What do we call a network? Whose network is it? Guys, the Chaitanya Network. Let's talk, what's wrong with his house? Whatever is associated with his router

29:58 Now that the topic is here, Networking is the word in this networking What happens when networking involves Designing Implementing and Managing The Connection Between Computers and Devices to enable communication and Resource Sharing It is a Broader Term That includes the activities associated With Building and Maintaining I know the networks are okay, if you look at this What we don't understand is a real time Let's go to the example. Now what? This is where you will find a BTech college. Can you see what branches are underneath? There are branches in B.Tech. You have an idea, CSC EC. Triple E and Civil are now B.Tech Anyone who has a degree like me, There are people who did it, they deserve it. So, BBA and BSC are like this. Now here directly about B.Tech Since we are talking, I am studying B.Tech. Let's take an example: CSC is a group. Guys, there are people at CSC. So what do we call them? We are a network. Let's say this CD is a network. That is, even in that group of people

30:43 There is a triple, it is a network civil What is a network B.Tech Management? It means that they are all together in one event. Guys, it says to organize. Who will be there? CSC people will be there. They will be triple e they will be They are civil, so what now guys? They all conducted the event together. If you want to do something, then you have to conduct it. What should they do directly? It can't happen without communication. It means we need to communicate with each other. Those called CSC are with these C people. These people who need to communicate are treble. You need to communicate with them, Tribble. They are civil, so they are one with one. Guys, you should keep communicating, that's all. The event is organized exactly. It can be seen here. What is CSC? It is a network. A group of people is called a network. So, who are the easy ones? A group of We call people a network. Civil Tribulation is a network for everyone. So let's combine now. The event is about talking. How to plan Who should we call? So who should be invited as the chief guest?

31:29 When all these things happen What happens is communication there. What do we mean by "it will happen"? Networking is so simple, guys. Now onto the real-time example. Let's go, Chaitanya's network, so what? Now that we have discussed So let's find out what a network is. If you want to see Next, you can see it here below. Images We are Chaitanya Eshwar Prasad like this Chaitanya says there are three people. We are still discussing the same at home. As expected, there is a laptop in his house. There are some devices, Ishwar. Something devices or something at home too There are many more in Prasad's house too. So what happens here? Three Kinds of Network Size is now simply put Chaitanya Network One Ishwar Network Two What will happen to Prasad Network Three now? These three communicate together. What does it mean to be able to do this? It can be confusing when we say networking. Here, it means that people communicate. What is happening here? Devices are communicating, guys.

32:14 Through routers These devices through routers Everything is communicating, which means What can be done here? Chaitanya Ishwar's data You can share it with Ishwar Prasad too. Prasade Chaitanya says data can be shared Can you do this to God? Can you do this to someone like this? That means people can share data. This is what we call networking, but Previous to this, the network The difference is that we guys on the network Data is only available at Chaitanya's house. Now we can share networking What happens in Chaitanya? He is Ishwar. He is called Prasad, he is also in that. You can share data, so this is it guys. Networking is so I think you guys are Clear about this network and Networking Concepts Network Types So First Of all these network types, Before you explore, you need to network. And if you don't watch networking videos Just look at that guys and this Come on, let's look at the types now. PAN Personal Area Network Land Local Area Network Land Wireless Local Area Network CAN Campus

33:00 Area Network Metropolitan Area Network and Storage Area Network One Wide Area Network So now we About Personal Area Network Let's find out what a personal area network is. Is a computer network for internet Connecting electronic devices with In an individual person's work Space fans can also connect by Using a USB cable I don't know this. You're confused just by looking at the description. Maybe, don't worry guys, so here it is. Let's see what we have, two devices. There is nothing but the laptop. And what happens here on a mobile phone? We are connected via Bluetooth, guys. What happens in Bluetooth is data Sharing is happening, but that's the song. Maybe a movie, maybe photos. So what happens here? His personal work for the individual Space switching is nothing but his He shares with personal devices only. Simply put, "can do it" means So to speak, Bluetooth guys, in that Bluetooth What happens if you are either 10 m away If you're gone, what's the point? Disconnect. Okay, right, it won't connect, otherwise.

33:46 Person A interrupts you with data. There's nothing to do, guys, only you. Your data is your personal components. This is nothing but the devices. It could be a laptop or a mobile. This is the only personal thing you can share with them. Area Network Next One is the Land a local area network This is your Everyone knows that once we Let's see the description, which local area? A network is a collection of devices. Connected together in one physical Location Such As A Building Office Are Home Simply put, this is a Imagine a house, guys, what is in a house? There is a router, so that router comes and connects to my mobile. Key and printer key and as well as That's for my laptop and computer too. It's connected, so what's going on here? Guys, it's a network that's been formed. This is only for my home network. What I mean by possible is that I suppose here. Share data from laptop to my mobile Can I print from my mobile? Can I share data from my printer? You can share data with the computer, so all this

34:32 What is the main point of a central device? They are connected through the same router. Okay, this is what a local area network is. I only have access to it until our house. I can do it even if I have an office. This is only accessible up to my office. I can do this network and the next one. Is the land wireless local area Network So let's read its description. A wireless land is a wireless Computer network that links to More Devices Using Wireless Communication to form a local area Network with a limited area such as us A home school computer laboratory Campus or office building so lan What do you mean, guys, we're just simple. We learned about LAN, didn't we? What's happening in the wide area wireless? I am connected to you, but what is this land? What is happening is only wireless. Connect guys here now You can see there is a router. What is the router for? Connects to iPod and laptop To the computer, to the printer, to the mobile Connects through what?

35:17 It will connect via WiFi. Simply put, we are a wireless local Area Network Which Is Nothing But The Land with WiFi This is a local area What technology do we use in this if not the network? We are using wireless technology. What we do is simply what we say. Let's say WiFi. And next one is the Con Campus Area network or campus network Campus Area Network Corporate Area Network or Can is a computer Network made up of interconnection of local area network within a Limited geographical area so in this What's actually happening guys? Now you can look at a university. If you look at the image here, three There are three universities. There are also land connections in Guys, is it University Land? There is a connection, another land connection. There is also a university for another. There is also a land connection, which is also a University but when these three are one Will they get closer and share resources? That is, to put it simply, now

36:03 You can check out some colleges like Mallareddy Colleges, if you look at things like this What happens is that most of the buildings there There are guys, not just one building. There are blocks, so what happens in which block? B is using a land network. What happens in a black land network? What happens in C block using a He is using the land network, so these three Blocks also share resources together. To do all this, you need a The network is connected. They are communicating between each other, so this is what What do we call the campus area? Network Man A Metropolitan Area A network is a computer network that Connects computers with a Metropolitan Area Which Could Be A Single Large City Multiple Cities and Towns are any given large area with Multiple buildings, so what's going on here? What happened in this previous video? Data of blocks or campuses Connect from through land networks We saw it happening, we saw it sharing here.

36:48 What's happening is that guys just got on campus. Cities in the Place of Universities Put RS in towns, they can become cities. Avvachu RS Large Area with Multiple Buildings Which Is Nothing But the larger the area, the multiple Buildings means there are many buildings. So these cities and everything What do we call something that connects? We are guys and next one is the Sandwiches which is nothing but the storage Where do we use an area network? Use to store storage Guys, you can see it's simple here. Data Array Switches Servers in Image What is our data stored on these servers? All storage is stored. Guys, why do we use it? Sting will come to you on your phone. There is very little storage, right? What happens in that? There's not enough space. Then what will we do with such a stand? Is Nothing But Storage Area Network We can directly use Our data communicates with servers. So we'll store it there. What are the discus switches in it? Servers So you know a little about these

37:35 First of all, if you want to know in detail You are talking about physical components. Guys should know about that too. There is a separate video, do check it out. And next one is the van which is Nothing but the wide area network is wide Area Network is the telecommunication Network That Extremes Over A Large geographical area Wide area Networks are established later. With lease telecommunication circuits So, to put it simply, Guy's Van That is, which is nothing but the Internet. That means you can use it from here. You can communicate anywhere. Like you are from India to America. Send a WhatsApp Hi message to him. Okay RS said hi on Instagram. Okay, he can reach it, why overalls? What happens to us is that we have a network Guys, that's how communication happens. What do we mean by this, simply put? We call it the Internet and this is the network. Types This network is called the network topology. Let's take a look at what topology is, which network? Topology is the physical and logical

38:21 Arrangements of Notes and Connections In a network notes usually Includes devices such as switches Routers and software with switch and I know router features, I'll read this to you. I don't understand, so let's clarify a little here. Let's see, guys, there are two types in this. What is meant by physical topology and Logical topology in physical topology The mains will come and the cables will revolve. There are cables, nothing but us. Land cables are simple. Physical devices land, so to speak All the cables will also revolve. So here is the logical topology. When it comes to topology, here is the data It keeps revolving, so just a little more. Let's learn about this in depth. The whole meaning here is physical topology. So there are certain types of things that come with this. Guy's Bus Topology Star Topology Ring Topology Mesh topology Tree topology Hybrid topology so about these types Let's find out for ourselves, so you have topology. First of all, if you want to understand about What you need to know about data Guys, here you can see the network layer.

39:06 Data Link Layer Physical Layer Network What happens at the layer is IP packets Okay guys, data is a packet. Below is the change in the data link layer. What happens is the frame changes under Change under cables in the physical layer It will be possible, we can see it here. Logically speaking, what do we call data? Let's say under the frame so here you are in the frame You can see that it is connected to the data link layer. So you have all these layers of confusion. If so, you can go to the osi model video. Guys, you can see it's clear in that video. What is this frame that is meant to be crystal? What is a packet? Why do we use this data like this? But here you are the only one. Remember, we are using data here. What do we say, frame, say OK and next? One bus topology So what is this bus topology? That means bus topology is a specific kind of network topology in which all of the Various devices in the network are Connected to a single cable or line so Here we can see that we are slowly approaching a point. Let's take it, so here you are. Let's see, guys, what is all this? It's a single line.

39:52 There is also a letter T in the right here. There are and what cables are here? There are what are there here? There are what pieces. B C D E Okay, you can see the right side here. You have TP connectors, so this is it. Come and have tea here, whatever you have. Okay guys, so here's what's included. What happens is the cable is here again. What happens is there is a cable under this? But when you have a frame Want to share what is nothing? But the data is transferred from here to here. When will you come here? If you want to send it, it will go to B. Guys, C goes to D, E goes to E. I will also go to but B C D reject. What it does is that the data is only Only that destination takes the data. But the problem here is that this data Guys, stay connected to everything. Next one is the start up topology Start Topology is a network topology In which each network component is Physically connected to a central node Such as a router, hub or switch here

40:37 You can see what happens in the image below. One Certain Systems Three Systems A hub or switch router in the middle What is all this about saying you can put it? Connect to a central device even together There are guys, that's all, as previously stated. What happened in topology? We call a wire a tee. Using connectors to connect our systems We connected, but that's not the case here. Connect to a hub or switch What we are using here means Does data go to everything? It definitely goes guys so its frames So let's see how it works before that. Let's find out, guys. There are two types: broadcast and Let's watch it first in the Unicast broadcast. Here you can see the frame by frame. What happens here if this is nothing but the data? A computer is under a frame. So, it says transfer is done under this. Take two computers, one of which Let's say one is B, so from A to B. Send data exactly to the destination. What happens if you send this broadcast? How much data does everything in the world cost?

41:23 Computers are everything, data is everything. I'll go, but I'll reject them all and lose. The source destination is the same as the destination. Simply put, this is okay with Hep. If you don't want to go to data at all Only direct me to the destination. I have to go even if they reject me. Even if I don't do it, it's still my destination. If you are determined to go, then What we do is use the switch. Let's start the switch is nothing but the What happens in this unique cast? Below you will find You can see that the computer above A is OK. So what happens here is that? It is a frame that is sent as a frame. Go to the switch and then back to the switch. It means B goes directly to B. It goes to that, it doesn't go to this. Why is it used as a previous broadcast? So what does "valla" mean, guys? Traffic directly to you in unicast It doesn't happen that being too much is a waste of time. But broadcast means every computer How many times does the data button go to Even if all those computers are registered It's all about reaching the destination, but time is of the essence. Traffic is a waste.

42:09 It's more common here in unicast. If you look at it, traffic is consumed. Guys next one is the switch cable Ethernet frame so you can see it here Switch How does this switch actually direct us? It is a little bit like sending it to the destination. Let's look at it in detail. So here is the address. The interface is Mac One B One Mac 2 b2 It's called Mach 3 b3, but guys, this is it. What do we mean by switch table? What happens here is a direct How to get the data to that computer? Guys, it's ready to send. A switch table in the switch MAC addresses are also a thing for everything. What is configuring the port? Let's say p1 p2 p3 so the same here You can see this in the othernet frame. What we mean is that we call it a frame, so here Source Mac Mac to Source Mac Witch Is Nothing but the one who The data they want to send is theirs, Mac. 2 means whoever receives the data Their IP datagrams frame check Sequence FCS All of these are also you Once you look at the os model, you will see

42:55 It is crystal clear. Guys, remember this for now. But what happens here is that certain Map back to the address and that port. It is configured so that That's why the switch sends it directly. Here we can see the switch in unicast. What does data from a computer do? But what if it is sent directly to B? What goes beyond that? Guys, I'm not going to the computer. Next one is the ring topology a ring Topology is a network configuration. Where devices connection created? Closed circular data path for me I understand, what might you not understand here? So you guys can see this image once. What happens here is ABCDEEFGH It says, "What's in the middle?" It means there's a frame. Now suppose what is here guys? Data from computer to computer Suppose it was sent, what would happen? Ring topology so going around It means going from A to B.

43:40 Data b to c to d d to e e From F so this data is revolved It's happening guys, what are you doing now? Okay, what else should I send from H to A? From B to B from C to C to D The data goes in a ring type like this What this will do is increase traffic. Maybe the second one will be a waste of time. Guys look here so token pass ring The function of topology is multi. What is the station access unit here? One physical component connects Data flows logically here. What is a multi-station access unit? Connect to it and actually do it again. In this too, data is one for each computer. Guys, what's going on here? The token is generated. When the token is generated, this token is whatever Only that token is sent after that data is there. Simply put, access is You can go to the bank anywhere. What happens if the bank gives you a The token will be given according to your token number. This means we will go directly.

44:26 The same thing happens to guys so let's mess around. Topology is a network. Setup Where Each Computer Network The device is interconnected with another Device What's not in this Every computer Also here you can see this white Think of lines as wiring, these are cables. Think about it, what is all this? Anyway, guys, stay connected now. F can be sent to A and B. Can you send it to H? Can you send it to G? Can you send it to G? Data is This means that it is circulating. Either one is cut or one is a wire. Whatever is lost, it's for something else. There is communication, guys. What's in it? You can share data with anyone. Now, to put it simply, we are a We are going on the road to a certain village. If you go by car, you have to go to a city there. No matter which way you go, you will reach the city. Okay, everything is connected there. There are roads, and so are they here. Guys, that data might be out of reach. Because one is connected to the other. Okay, next one is tree topology. What is this?

45:12 No, this is like a tree shape. Imagine guys star topology and bus This is what it looks like when you combine the topology. We call tree topology a hybrid topology. Which is nothing but a topology It uses multiple topologies. If we keep this, we call it a hybrid topology. Antam Network Devices Network Devices Also Known As Networking Hardware or physical devices that allow Hardware on a computer Communicate and interact with one another So, to put it simply, the definition So guys, anytime we have a physical Share data from components We will see what to do because a From computer to computer Through the Internet, we can do anything. A certain physical device is essential. Guys, without that physical device, we It means we can't interact directly. With data, we have some devices in it. Now let's see about So let's see The first device arrived, and it was called nic. What is meant by network interface card?

45:58 They say this, so what does it do? Simply put, once the definition Let's see what is the NIC or network interface. The card is a network adapter that is Used to connect the computer to the Network It is installed in the Computer to Establish a Lab It Has a unique ID that is written on the Chip and it has a connected to Connect the cable to it. Acts as an interface between the The computer and the router are model so To put it simply, guys, how are we? However, there is an address on the Aadhar card. A unique identity for each device It means that our computer is there. A computer has a MAC address, that's all. Apart from that, we have our mobile phone. Does the phone have a MAC address or something? Our web camera is smart web. The camera has a MAC address. So what does this MAC address represent? What it does is actually who you are. What I'm saying is that it's okay for systems. Now I have my laptop. This is my laptop. How do we configure that? Let's do it, the real data is our laptop.

46:44 How does it work? It works because of the MAC address. Guys, what is this unique MAC address? If you assign, assign this nick card. This is the network that does it. Let's say interface card, we have an image here. You can see it in So That's It Guys So Next time I come to the hub, what is actually the hub? What you are doing is in the picture here. Look, guys, it's in the middle. This is what we call a hub, but this hub It is a certain four systems

…
