Q.2. Explain the concept of information gathering in ethical hacking. Differentiate between passive and active information gathering techniques, and discuss the role of footprinting, scanning, and enumeration in the reconnaissance process. (3+3+4 = 10 Marks)

Ans 2.

Information Gathering: Gathering information about a target prior to studying its security. In the context of ethical hacking, it aids the hacker in gaining insight into the organisation’s systems and their presence, technologies and potential vulnerabilities. The results inform subsequent testing which is authorized within the scope of

 

 

Q.3. Define network scanning and explain its importance in ethical hacking. Discuss host discovery, ping sweep, and TCP/IP scanning techniques, and explain the role of port scanning in identifying network services. (3+3+4 = 10 Marks)

Ans 3.

Network scanning: The act of “scanning” a network to discover reachable devices, exposed ports, and available services. In the process of ethical hacking, it enables the ethical hacker to get an insight into the attack surface of the network.

Q.5. Define malware and explain its role in cybersecurity threats. Differentiate between viruses, worms, and Trojans, and discuss their impact on computer systems and networks. (4+6 = 10 Marks)

Ans 5.

Malware is a program that is used to cause damage or to perform unauthorized actions on a device or network.

Malware can be sent via misleading downloads, compromised files, removable media or vulnerabilities in software and network services.

Role in Cybersecurity Threats

Malware will frequently

 

Q.6. Define social engineering and explain its significance in cybersecurity. Discuss phishing, baiting, quid pro quo, and pretexting techniques, and explain appropriate measures for preventing social engineering attacks. (4+6 = 10 Marks)

Ans 6.

Social Engineering is the art of getting information out of people, or getting them to do something that compromises security. Rather than just a software vulnerability, the attacker leverages trust, fear, curiosity, helpfulness, or urgency. Requests can come in by e-mail, phone, text, or in person.
