45+ [REAL-TIME] Penetration Testing Interview Questions and Answers

Last updated on 12th Apr 2024, Popular Course

Penetration testing, commonly known as pen testing, is a pivotal proactive security assessment methodology employed by organizations to evaluate the robustness of their IT infrastructure, networks, and applications. This approach involves emulating real-world cyber attacks to uncover potential vulnerabilities that could be exploited by malicious entities. The process typically follows a systematic approach, commencing with reconnaissance and information gathering, progressing to vulnerability identification and exploitation, and culminating in comprehensive reporting.

1. What is penetration testing, and why is it important?

Ans:

A simulated cyberattack is used in penetration testing to examine computer systems for vulnerabilities that might be exploited. Penetration testing is used to supplement a web application firewall in the web application security. It’s crucial because it evaluates the possible consequences of security breaches, finds security flaws in a system’s defenses that attackers may exploit, and confirms the efficacy of security measures that are already in place.

2. Can you explain the different types of penetration testing?

Ans:

• Three types of penetration testing exist: black-box, white-box, and slate-box. Black-box testing emulates an external attack, devoid of prior knowledge about the system.
• White-box testing provides the tester with a complete understanding of the structure, including network plates, source law, and IP addressing information, offering a thorough assessment of internal security.
• Grey-box testing is a combination of both, where the tester has partial knowledge of the system. Each type offers unique advantages and is chosen based on the specific pretensions of the test.

• Surveillance is the phase where information about the target is collected. Scanning involves relating live hosts, open anchorages, and services. 
• Gaining access refers to exploiting vulnerabilities to enter the system. Maintaining access involves ensuring a patient presence in the exploited system. 
• Eventually, analysis and reporting involve collecting findings, vulnerabilities, exploited systems, and recommended countermeasures.

5. How do you stay streamlined with the most security vulnerabilities?

Ans:

Staying streamlined with the most security vulnerabilities is pivotal for a penetration tester. This can be achieved by regularly checking sanctioned vulnerability databases like the National Vulnerability Database( NVD) or CVE List, following security forums and newsletters, sharing in security conferences, and being active in the cybersecurity community.
