- 4. What is Cyber Attack? • A cyber attack is any type of offensive maneuver that targets computer information systems, infrastructures, computer networks, or personal computer devices. Usually, the attacker seeks some type of benefit from disrupting the victim’s network. • An attacker is a person or process that attempts to access data, functions or other restricted areas of the system without authorization, potentially with malicious intent. • Malware, Phishing, Man-in-the- middle attack, Denial-of-service attack, SQL injection etc. are the common types of cyber attack.
- 6. What is Cyber Security? • Cyber security is the practice of defending computers, servers, mobile devices, electronic systems, networks, and data from malicious attacks. • It's also known as information technology security or electronic information security. • The term applies in a variety of contexts, from business to mobile computing, and can be divided into a few common categories. Such as Network security, Application security, Information security & Operational security.
- 7. Why Cyber Security? To build a computer system that prevents hackers’ access and safeguard system and information from malicious attack. To manage adequate preventive measures in order to avoid security breaches. To safeguard user or customer information available in business transactions and visits. To test networks at regular intervals. To create security awareness at all levels in a business. 0 100 200 300 400 500 600 700 800 900 2010 2011 2012 2013 2014 2015 2016 2016 2017 2018 Total Malware Infection Growth Rate

- 10. Who is Hacker? “Hacker" is someone who explores methods for breaching defenses & exploiting weaknesses in a computer system or network. Hacking is the act of finding possible entry points which exist in a computer system or network and entering into one of these. Hacking is usually carried out to gain unauthorized access to a computer system or network for negative purposes such as to harm or steal the sensitive information from the computer.
- 11. Types of Hackers Black Hat Hackers Black Hat hackers, also known as crackers, are those who hack in order to gain unauthorized access to a system and harm its operations or steal sensitive information. Black Hat hacking is always illegal because of its bad intent which includes stealing corporate data, violating privacy, damaging the system, blocking network communication, etc. White Hat Hackers White Hat hackers are also known as Ethical Hackers. They never intent to harm a system, rather they try to find out weaknesses in a computer or a network system as a part of penetration testing and vulnerability assessments. Ethical hacking is not illegal and it is one of the demanding jobs available in the IT industry. Grey Hat Hackers Grey hat hackers are a blend of both black hat and white hat hackers. They act without malicious intent but for their fun, they exploit a security weakness in a computer system or network without the owner’s permission or knowledge. Their intent is to bring the weakness to the attention of the owners and getting appreciation.
- 12. What is Ethical Hacking? • Ethical Hacking is an authorized practice of bypassing system security to identify potential data breaches and threats in a network. This information is then used by the organization to improve the system security, to minimize or eliminate any potential attacks. • The company that owns the system or network allows Cyber Security experts to perform such activities in order to test the system’s defenses. Thus, unlike malicious hacking, this process is planned, approved, and more importantly, legal. • Ethical hackers duplicate the techniques and methods followed by malicious hackers in order to find out the system discrepancies, replicating all the latter’s steps to find out how a system attack occurred or may occur.
