\n<\/div>\nTop Ethical Hacking Interview Questions for Freshers with Answers.<\/h2>\n1. What is hacking?<\/h2>\n
Hacking<\/strong> is the practice of identifying and exploiting weaknesses<\/strong> in a computer system, network, or application to gain unauthorized access<\/strong>. It can be for malicious<\/strong> or ethical purposes<\/strong>.<\/p>\n2. What is ethical hacking?<\/h2>\n
Ethical hacking<\/strong> is authorized hacking to test and strengthen system security<\/strong> by finding vulnerabilities before malicious actors<\/strong> can exploit them. Certified ethical hackers<\/strong> often conduct these tests.<\/p>\n3. What is penetration testing?<\/h2>\n
Penetration testing<\/strong> simulates real attacks to evaluate and improve a system\u2019s security defenses<\/strong>. It identifies weak spots<\/strong> by replicating attack scenarios<\/strong>.<\/p>\n4. What are black hat, white hat, and gray hat hackers?<\/h2>\n
White hats<\/strong> hack legally for security<\/strong>, black hats<\/strong> hack with malicious intent<\/strong>, and gray hats<\/strong> operate in both ethical and unethical areas<\/strong> based on circumstance.<\/p>\n5. What is a vulnerability?<\/h2>\n
A vulnerability<\/strong> is a flaw or security weakness<\/strong> in a system that attackers can exploit to gain unauthorized access<\/strong> or cause harm.<\/p>\n6. What is malware?<\/h2>\n
Malware<\/strong> is a general term for malicious software<\/strong> like viruses, worms, Trojans<\/strong>, designed to cause damage or access data illegally<\/strong>.<\/p>\n7. What is a virus?<\/h2>\n

Encryption<\/strong> transforms data into unreadable code<\/strong> to protect it from unauthorized access, using algorithms and keys<\/strong>.<\/p>\n18. What is decryption?<\/h2>\n
Decryption<\/strong> is the process of converting encrypted data<\/strong> back into its original, readable format<\/strong> using a decryption key<\/strong>.<\/p>\n19. What is a firewall?<\/h2>\n
A firewall<\/strong> is a network security tool that monitors and filters traffic<\/strong> based on a set of security rules<\/strong>.<\/p>\n20. What is a proxy server?<\/h2>\n
A proxy server<\/strong> acts as an intermediary between a user and the internet<\/strong>, masking the user\u2019s IP address<\/strong> to enhance privacy.<\/p>\n21. What is a honeypot?<\/h2>\n
A honeypot<\/strong> is a decoy system<\/strong> set up to attract attackers<\/strong> and analyze their techniques without risking real data.<\/p>\n22. What is an intrusion detection system (IDS)?<\/h2>\n
An IDS<\/strong> detects suspicious network activities<\/strong> and sends alerts, helping to monitor potential security breaches<\/strong>.<\/p>\n23. What is an intrusion prevention system (IPS)?<\/h2>\n
An IPS<\/strong> actively blocks malicious activities on a network, stopping attacks as they happen, unlike an IDS<\/strong>, which only detects them.<\/p>\n24. What is network sniffing?<\/h2>\n
Network sniffing<\/strong> captures and analyzes network packets<\/strong>, potentially revealing sensitive information like passwords<\/strong> or data<\/strong>.<\/p>\n25. What is a hash function?<\/h2>\n
A hash function<\/strong> generates a unique value<\/strong> or \u201chash\u201d from data, used for data verification<\/strong> and integrity checks<\/strong>.<\/p>\n26. What is SSL\/TLS?<\/h2>\n
SSL\/TLS<\/strong> are protocols for securing data transmission<\/strong> over the internet, providing encryption<\/strong> between clients and servers.<\/p>\n27. What is a man-in-the-middle (MITM) attack?<\/h2>\n
An MITM attack<\/strong> intercepts communication between two parties, allowing the attacker to read<\/strong> or modify<\/strong> the exchanged data.<\/p>\n28. What is data exfiltration?<\/h2>\n
