1. Web Security Introduction to Ethical Hacking, Ethics, and Legality

2. Hacker The term hacker conjures up images of a young computer whiz who types a few commands at a computer screen—and poof! The computer spits out passwords, account numbers, or other confidential data. Hacking The Process by which hacker spits out passwords, account numbers, or other confidential data is called hacking.

3. Types of Hacker Hacker can be divided into three groups 1. Black Hats 2. White Hats 3. Gray Hats

4. White Hats White hats are the good guys. The ethical hackers who use their hacking skills for defensive purposes. White-hat hackers are usually security professionals with knowledge of hacking and the hacker toolset and who use this knowledge to locate weaknesses and implement countermeasures.

5. White hats are those who hack with permission from the data owner. White hats hacker do hacking on a contract only.

6. Black hats Black hats are the bad guys The hackers or crackers who use their skills for illegal purposes. Having gained unauthorized access, black-hat hackers destroy vital data, deny legitimate users service, and just cause problems for their targets

7. Gray Hacker Gray hats are hackers who may work offensively or defensively. They may want to highlight security problems in a system The difference between white hats and gray hats is that permission word.

8. Goals Attackers Try to Achieve Confidentiality ◦ Information (Keep information safe) Authenticity ◦ being authentic, trustworthy, or genuine. Integrity ◦ Accuracy Its opposite is data corruption Availability

9. Some Useful Terminology Threat ◦ An environment or situation that could lead to a potential breach of security. Exploit ◦ A piece of software or technology that takes advantage of a bug, leading to unauthorized access

10. Vulnerability ◦ software flaw, or logic design that can lead to damaging instructions to the system Target of Evaluation (TOE) ◦ A system, program, or network that is the subject of a security analysis or attack. Attack

11. The Phases of Ethical Hacking The process of ethical hacking can be broken down into five distinct phases.

12. Phase-I: Reconnaissance Passive reconnaissance ◦ Passive reconnaissance involves gathering information about a potential target without the targeted individual’s or company’s knowledge. ◦ Such as using “whois.com” or google.com etc Active reconnaissance ◦ involves probing the network to discover individual hosts, IP addresses, and services on the network. This process involves more risk of detection than passive reconnaissance

13. Phase 2: Scanning Scanning involves taking the information discovered during reconnaissance and using it to examine the network. Hackers are seeking any information that can help them perpetrate an attack on a target, such as the following: ◦ Computer names ◦ Operating system (OS) ◦ Installed software ◦ IP addresses ◦ User accounts

14. Phase 3: Gaining Access Phase 3 is when the real hacking takes place. Gaining access is known in the hacker world as owning the system because once a system has been hacked, the hacker has control and can use that system as they wish.

15. Phase 4: Maintaining Access Once a hacker has gained access to a target system, they want to keep that access for future exploitation and attacks. Once the hacker owns the system, they can use it as a base to launch additional attacks. In this case, the owned system is sometimes referred to as a “zombie system”.

16. Phase 5: Covering Tracks Once hackers have been able to gain and maintain access, they cover their tracks to avoid detection by security personnel, to continue to use the owned system, to remove evidence of hacking, or to avoid legal action.

17. Common Entry Points for an attack: Here are the most common entry points for an attack: 1. Remote Network ◦ Attack through Internet, ◦ Hacker Tried to break, or find vulnerabilities in a network such as firewall, proxy etc. 2. Remote Dial-Up Network ◦ A remote dial-up network hack tries to simulate an intruder launching an attack against the client’s modem pools.

18. 3. Local Network Through Local Area Network (LAN) or Wireless Local Area Network(WLAN) More secure then Dail-up 4. Stolen Equipment ◦ Some time hacker find useful information from stolen equipment, such as usernames, password, security setting, and encryption types etc. from stolen Equipment

19. 5. Social Engineering ◦ Take information from organization employees, or from help desk or using to common sense.

20. Testing Types Testing types can categorize on basis of knowledge of hacker about target. 1. Black-Box Testing ◦ Black-box testing involves performing a security evaluation and testing with no prior knowledge of the network infrastructure or system to be tested. ◦ Information gathering will take a long time.

21. 2. White-box testing ◦ White-box testing involves performing a security evaluation and testing with complete knowledge of the network infrastructure ◦ Hack will not spend time on information gathering

22. 3. Gray Box Testing ◦ Gray Box Gray-box testing involves performing a security evaluation and testing internally. ◦ Test the system against the employee of the organization.

24. Ethical Hacking Report The result of a network penetration test or security audit is an ethical hacking, or pen test report. This report details the results of the hacking activity, the types of tests performed, and the hacking methods used This document is usually delivered to the organization in hard-copy format, for security reasons.

25. Keeping It Legal The following steps (shown in Figure) are a framework for performing a security audit of an organization and will help to ensure that the test is conducted in an organized, efficient, and ethical manner

26. Initial Client Meeting Sign the Agreement Security Evaluation Plan Conduct the Test Report and Documentation Present the report
