Candidates should be well-prepared to tackle both the Ethical Hacking Online Assessment and the Technical Interview Round at IDM TechPark. To help you succeed, we have compiled a comprehensive list of the Top 100 Ethical Hacking Interview Questions along with their answers. Mastering these concepts will give you a strong edge in securing an Ethical Hacking role and excelling in the field of cybersecurity and ethical hacking.
1. What is Ethical Hacking?
Answer:
Ethical hacking involves legally and systematically testing computer systems and networks for vulnerabilities, with permission, to strengthen security.
2. What is Penetration Testing?
Answer:
Penetration Testing is a method of evaluating security by simulating an attack on a system to identify weaknesses that could be exploited.
3. What is the difference between White Hat, Black Hat, and Gray Hat hackers?
Answer:
-
White Hat: Ethical hackers who test systems with permission.
-
Black Hat: Malicious hackers who exploit vulnerabilities illegally.
-
Gray Hat: Hackers who may violate laws but typically have no malicious intent.
4. What is Vulnerability Assessment?
Answer:
Vulnerability Assessment is the process of scanning and identifying potential security weaknesses in a system or network.
5. What are the phases of a penetration test?
Answer:
The common phases include Reconnaissance, Scanning, Enumeration, Exploitation, Post-Exploitation, and Reporting.
6. What is Footprinting?
Answer:
Footprinting is the initial phase of information gathering, where public information about the target is collected to understand its structure and vulnerabilities.
7. What is Network Scanning?
Answer:
Network Scanning identifies live hosts, open ports, and services running on a network, typically using tools like Nmap.
8. What is Enumeration in Ethical Hacking?
Answer:
Enumeration extracts detailed information from a target system (e.g., user names, network shares) to find vulnerabilities.
9. What is Exploitation?
Answer:
Exploitation is the phase where vulnerabilities are actively used to gain unauthorized access or control over a system.
10. What is Post-Exploitation?
Answer:
Post-Exploitation involves gathering further information and establishing persistence after a successful breach to evaluate the impact.
11. What is Social Engineering?
Answer:
Social Engineering uses human interaction, deception, and manipulation to trick individuals into revealing confidential information.
12. What is a Firewall, and how can it be bypassed?
Answer:
A firewall is a security device that monitors and controls network traffic. Bypassing a firewall can involve techniques like tunneling, using proxies, or exploiting misconfigurations (always performed ethically with permission).
13. What is a VPN and its role in security?
Answer:
A VPN (Virtual Private Network) creates a secure, encrypted connection over the internet, protecting data from interception during transmission.
14. What is Port Scanning?
Answer:
Port scanning identifies open ports and services on a network, often using tools like Nmap, to find potential entry points for an attack.
15. What is SQL Injection?
Answer:
SQL Injection is an attack that inserts malicious SQL code into input fields to manipulate the database. Preventive measures include input validation and prepared statements.
16. What is Cross-Site Scripting (XSS)?
Answer:
XSS is an attack where malicious scripts are injected into web pages viewed by other users. Mitigation includes proper input sanitization and output encoding.
17. What is a Denial-of-Service (DoS) attack?
Answer:
A DoS attack overwhelms a system with traffic or requests, causing it to become unavailable to legitimate users.
18. What is a Buffer Overflow?
Answer:
A Buffer Overflow occurs when data exceeds a buffer’s capacity, potentially allowing attackers to execute arbitrary code or crash a system.
19. What is Encryption?
Answer:
Encryption converts data into a coded format to protect it from unauthorized access. It is essential for secure data transmission and storage.
20. What is Two-Factor Authentication (2FA)?
Answer:
2FA requires two forms of verification (e.g., password and a temporary code) to enhance account security beyond just a password.
21. What is a Honeypot in cybersecurity?
Answer:
A Honeypot is a decoy system designed to lure attackers, allowing security teams to study attack methods and enhance defenses.
22. What is the role of Ethical Hacking in Cybersecurity?
Answer:
Ethical hacking helps organizations identify vulnerabilities, assess risk, and strengthen security defenses before malicious attackers exploit weaknesses.
23. What is Risk Assessment in Ethical Hacking?
Answer:
Risk Assessment identifies, evaluates, and prioritizes risks to the system, helping to decide which vulnerabilities to address first.
24. What is an API Test?
Answer:
API Testing verifies that the application programming interfaces (APIs) function correctly, ensuring proper data exchange and security between systems.
25. What are common tools used in Ethical Hacking?
Answer:
Common tools include Nmap (network scanning), Metasploit (exploitation framework), Wireshark (network protocol analyzer), Burp Suite (web vulnerability scanning), and John the Ripper (password cracking).
