JAWAHARLAL NEHRU TECHNOLOGICAL UNIVERSITY HYDERABAD MCA 2020 ETHICAL HACKING Previous Question Paper (October / November - 2020 - R15)

To become an ethical hacker, one must possess a combination of technical proficiency, analytical thinking, and a strong ethical foundation. Key skills include:

• Networking Skills: Deep understanding of TCP/IP, DNS, subnetting, and routing protocols to analyze network traffic and identify vulnerabilities.
• Operating Systems Proficiency: Expert-level knowledge of Linux (especially Kali Linux) and Windows, including command-line interfaces and system administration.
• Programming and Scripting: Ability to write and read code in languages such as Python, Bash, C, C++, and SQL to automate tasks and exploit vulnerabilities.
• Database Management: Understanding of SQL and database structures to identify and prevent injection attacks.
• Security Tools Mastery: Proficiency in using tools like Nmap, Wireshark, Metasploit, Burp Suite, and Nessus.
• Problem-Solving and Analytical Thinking: The ability to think like an attacker to anticipate threats and devise effective countermeasures.
• Soft Skills: Strong reporting and communication skills to document findings clearly for stakeholders, along with a strict adherence to ethical guidelines and legal frameworks.

Attackers are generally categorized based on their intent, skill level, and relationship with the target organization:

• White Hat Hackers (Ethical Hackers): These are security professionals who use their skills for defensive purposes. They have explicit permission to test systems and aim to identify and fix security flaws before malicious actors can exploit them.
• Black Hat Hackers: These individuals perform illegal activities with malicious intent. They exploit vulnerabilities for personal gain, financial theft, data destruction, or corporate espionage.
• Grey Hat Hackers: These hackers operate in a moral grey area. They may access systems without permission, but they do not necessarily intend to cause damage. They might notify the owner of a vulnerability after finding it, sometimes requesting a fee for the information.
• Script Kiddies: These are amateur hackers with limited technical knowledge. They rely on pre-written tools and scripts developed by others to launch attacks, often without fully understanding the underlying mechanics.
• State-Sponsored Hackers: Highly skilled individuals or groups funded by governments to conduct cyber-warfare, espionage, or sabotage against other nations or organizations to achieve political or strategic goals.
• Hacktivists: These attackers are motivated by political, social, or religious causes. They use hacking techniques to deface websites, leak sensitive information, or disrupt services to draw attention to their cause.
• Insider Threats: These are individuals within an organization, such as employees or contractors, who use their authorized access to cause harm, whether intentionally or through negligence.
