Sample VAPT Practical Skills and Knowledge Questions

Technical Proficiency Questions

1. Describe the process for using Nmap to perform a network scan.

• Answer: To use Nmap for network scanning, follow these steps:
  • Install Nmap: Ensure Nmap is installed on your system.
  • Run a Basic Scan: Use the command nmap [target IP] to perform a basic scan of the target.
  • Perform a Detailed Scan: Use options like -sS for TCP SYN scan or -sU for UDP scan to get more detailed results.
  • Analyze Results: Review the output to identify open ports and services.

2. How would you use Metasploit to exploit a vulnerability?

• Answer: To use Metasploit for exploitation:
  • Open Metasploit: Start the Metasploit console using msfconsole.
  • Search for Exploits: Use the command search [vulnerability] to find relevant exploits.
  • Select and Configure an Exploit: Use use [exploit] and configure required options with set [option] [value].
  • Run the Exploit: Execute the exploit with the run command and analyze the results.

Analytical Skills Questions

1. How do you prioritize vulnerabilities found during an assessment?

• Answer: Vulnerabilities are prioritized based on:
  • Severity: Use CVSS scores to assess the impact of vulnerabilities.
  • Exploitability: Determine how easily a vulnerability can be exploited.
  • Impact: Evaluate the potential damage if the vulnerability is exploited.
  • Context: Consider the specific environment and how the vulnerability affects it.

2. What should be included in a VAPT report?

• Answer: A comprehensive VAPT report should include:
  • Executive Summary: A high-level overview of findings for management.
  • Detailed Findings: In-depth analysis of vulnerabilities, including evidence and impact.
  • Recommendations: Actionable steps for remediation.
  • Conclusion: Summary of the overall security posture and any critical issues.

Knowledge of Security Policies and Procedures Questions

1. What steps should be taken to ensure compliance with security regulations during a VAPT?

• Answer: To ensure compliance:
  • Obtain Authorization: Secure written consent from relevant stakeholders.
  • Follow Regulations: Adhere to regulations such as GDPR or PCI-DSS.
  • Document Procedures: Maintain detailed records of the testing process and findings.
  • Protect Data: Implement measures to protect sensitive information.

2. How should sensitive data be handled during a VAPT?

• Answer: Sensitive data should be:
  • Encrypted: Use encryption for data both in transit and at rest.
  • Access Controlled: Restrict access to sensitive data to authorized personnel only.
  • Securely Stored: Store data in secure environments with access controls.

Best Practices for Demonstrating VAPT Practical Skills
