Recruiters often ask questions that test both theoretical knowledge and practical experience. The questions below represent some of the most frequently asked topics in an ethical hacker interview, covering penetration testing processes, web vulnerabilities, security tools, and responsible disclosure practices.
Question 1: Explain the difference between ethical hacking and malicious hacking.
Ethical hacking is performed with authorization to identify and fix vulnerabilities in systems. Malicious hacking, on the other hand, involves unauthorized access with the intention of stealing data, causing damage, or exploiting systems.
Question 2: Walk through the steps of a penetration test.
A typical penetration test includes planning and reconnaissance, scanning for vulnerabilities, gaining access, maintaining access for analysis, and finally reporting the findings along with recommended security improvements.
Question 3: What is SQL injection, and how do you prevent it?
SQL injection occurs when attackers insert malicious SQL queries into input fields to manipulate databases. It can be prevented through input validation, parameterized queries, and using prepared statements.
Question 4: Describe tools like Nmap, Metasploit, and Burp Suite.
Nmap is used for network scanning and identifying open ports. Metasploit is a penetration testing framework used for exploiting vulnerabilities in a controlled environment. Burp Suite helps test web application security by intercepting and analyzing HTTP requests.
Question 5: How would you handle a detected vulnerability in a live system?
An ethical hacker should document the vulnerability, assess its severity, report it responsibly to the appropriate team, and suggest mitigation strategies before any exploitation occurs.
Question 6: What is XSS, and what’s the difference between reflected and stored XSS?
Cross-site scripting (XSS) is a vulnerability that allows attackers to inject malicious scripts into web pages. Reflected XSS executes immediately through user input, while stored XSS persists in the application’s database and affects multiple users.
Question 7: Explain cryptography basics (symmetric vs. asymmetric keys).
Symmetric encryption uses a single key for both encryption and decryption, while asymmetric encryption uses a public key for encryption and a private key for decryption, providing stronger security for communication.
Question 8: Scenario: You’re testing a web app—how do you find hidden directories?
Ethical hackers use directory brute-forcing tools such as DirBuster or Gobuster to discover hidden directories and files within a web application.
Question 9: What are zero-day exploits, and how do ethical hackers prepare for them?
Zero-day exploits target vulnerabilities that are unknown to the software vendor. Ethical hackers stay prepared by monitoring threat intelligence reports and applying proactive security testing.
