- 3. Before we start Understanding the term CYBER It is a combining form relating to information technology, the internet and virtual reality relating to or characteristic of the culture of computers, information technology, and virtual reality - Google Cyber came from cybernetics In the late 1940s, cybernetics arose as the study of control systems and communications between people and machines. Today, it has evolved into a transdisciplinary approach to regulatory systems. 3

- 6. 1.Virus program that loaded onto computer without one's knowledge and runs against/without user permission
- 7. “ A computer virus is a type of computer program that, when executed, replicates itself by modifying other computer programs and inserting its own code. When this replication succeeds, the affected areas are then said to be "infected" with a computer virus.. 7
- 8. Solution 8 Removing a computer virus or spyware can be difficult without the help of malicious software removal tools. Some computer viruses and other unwanted software reinstall themselves after the viruses and spyware are detected and removed. Fortunately, by updating the computer and by using malicious software removal tools, you can help permanently remove unwanted software. Install a security suite that protects the computer against threats such as viruses and worms Install latest update of OS and Antivirus
- 10. 2. Malware software that is specifically designed to disrupt, damage, or gain unauthorized access to a computer system.
- 11. “ Malware is the collective name for a number of malicious software variants, including viruses, ransomware and spyware. Shorthand for malicious software, malware typically consists of code developed by cyber attackers, designed to cause extensive damage to data and systems or to gain unauthorized access to a network. 11
- 12. Types of Malware 12 Spyware: No surprise here — spyware is malware designed to spy on you. It hides in the background and takes notes on what you do online, including your passwords, credit card numbers, surfing habits, and more. Worms: Worms infect entire networks of devices, either local or across the internet, by using network interfaces. It uses each consecutively infected machine to infect others. Ransomware: This kind of malware typically locks down your computer and your files, and threatens to erase everything unless you pay a ransom. Adware: Though not always malicious in nature, aggressive advertising software can undermine your security just to serve you ads — which can give other malware an easy way in. Plus, let’s face it: pop-ups are really annoying. Botnets: Botnets are networks of infected computers that are made to work together under the control of an attacker.
- 13. How to protect against malware 13 Don’t trust strangers online! “Social engineering”, which can include strange emails, abrupt alerts, fake profiles, and curiosity-tickling offers, are the #1 method of delivering malware. If you don’t know exactly what it is, don’t click on it. Double-check your downloads! From pirating sites to official storefronts, malware is often lurking just around the corner. So before downloading, always double-check that the provider is trustworthy by carefully reading reviews and comments. Get an ad-blocker! Malvertising – where hackers use infected banners or pop-up ads to infect your device – is on the rise. You can’t know which ads are bad: so it’s safer to just block them all with a reliable ad-blocker. Careful where you browse! Malware can be found anywhere, but it’s most common in websites with poor backend security, like small, local websites. If you stick to large, reputable sites, you severely reduce your risk of encountering malware.
- 14. 3. Trojan Virus is any malware which misleads users of its true intent.
- 15. “A Trojan horse or Trojan is a type of malware that is often disguised as legitimate software. Trojans can be employed by cyber-thieves and hackers trying to gain access to users' systems. Users are typically tricked by some form of social engineering into loading and executing Trojans on their systems. Once activated, Trojans can enable cyber-criminals to spy on you, steal your sensitive data, and gain backdoor access to your system. 15
- 16. These actions can include: 16 Deleting data Blocking data Modifying data Copying data Disrupting the performance of computers or computer networks
- 17. 5. Hacker a person who uses computers to gain unauthorized access to data.
- 18. “ A hacker is an individual who uses computer, networking or other skills to overcome a technical problem. The term hacker may refer to anyone with technical skills, but it often refers to a person who uses his or her abilities to gain unauthorized access to systems or networks in order to commit crimes. A hacker may, for example, steal information to hurt people via identity theft, damage or bring down systems and, often, hold those systems hostage to collect ransom. 18
- 19. White A hacker who uses hacking skills to protect organizations from threat actors is called as a “white hat hacker.” They actively search for vulnerabilities in a security system so that the flaws can be patched before a cybercriminal can take advantage of them to penetrate the system Types of Hackers Black black hat hackers usually have extensive knowledge about breaking into computer networks and bypassing security protocols. They are also responsible for writing malware, which is a method used to gain access to these systems. 19 Grey These types of hackers are not inherently malicious with their intentions; they’re just looking to get something out of their discoveries for themselves. Usually, grey hat hackers will not exploit the found vulnerabilities. However, this type of hacking is still considered illegal because the hacker did not receive permission from the owner prior to attempting to attack the system.
- 20. Role of a White Hat Hacker ⬡ Scanning ports to identify flaws – White hat hackers use port scanning tools (such as Nessus or Nmap) to find whether there are any open ports. They study these ports in detail to come up with countermeasures to defend them against cyberattacks. ⬡ Examine patch installations – They also examine patch installations so that threat actors can’t exploit them. ⬡ Social engineering methods – They use social engineering methods, such as shoulder surfing, to collect crucial information. The steps that can help any cybercriminal to gain access to sensitive data. ⬡ Dodge honeypots, IDS, or other systems – White hat hackers also try different methodologies and approaches to evade honeypots set up by the organization. They look for loopholes that can give black hats the access to avoid firewalls, IDS/IPS ((Intrusion Detection Systems/Intrusion Prevention Systems), or honeypots. ⬡ Sniffing – They also perform network sniffing, hijacking web servers, and other network-related loopholes. 20

- 22. “We can never stop a Hacker to hack something the only thing we can do to protect computers is Creating HURDLES for the Hacker. 22
- 23. Why are we and organizations are hiring hacking to hack our own systems? 23 To catch a thief, you must think like a thief. That’s the basis for ethical hacking. Knowing your enemy is absolutely critical and very important. This may help you in creating the strategy for catching the hackers in the system. We try to hack our own systems so that we will be able to know the loop holes in the administration. This will help you in making precautions. You don’t have to protect your systems from everything. You can’t. The only protection against everything is to unplug your computer systems and lock them away so no one can touch them — not even you. But doing so is not the best approach to information security, and it’s certainly not good for business. What’s important is to protect your systems from known vulnerabilities and common attacks, which happen to be some of the most overlooked weaknesses in many organizations.
- 24. Your overall goals as an ethical hacker are to 24 Prioritize your systems so you can focus your efforts on what matters. Hack your systems in a nondestructive fashion. Enumerate vulnerabilities and, if necessary, prove to management that vulnerabilities exist and can be exploited. Apply results to remove the vulnerabilities and better secure your systems.
- 26. As we move forward in the digital age, cybersecurity should be a core business objective, no matter how large or small your business is — and being proactive can only protect you. Make it a priority today. 26
- 27. “ If you know the enemy and know yourself, you need not to fear the results of a hundred battles. If you know yourself but not the enemy , for every victory gained you will also suffer a defeat. If you know neither the enemy nor yourself, you will succumb in every battle.” In the world of cyber – You Neither Know Your Enemy Nor Yourself! 27
