Penetration Testing for OWASP Top 10
1. Introduction
Penetration testing is a crucial aspect of ensuring the security of web applications. This lesson focuses on penetration testing methodologies in relation to the OWASP Top 10 vulnerabilities, a standard classification of the most critical security risks to web applications.
2. OWASP Top 10 Overview
The OWASP Top 10 is a list of the ten most critical web application security risks:
- Broken Access Control
- Cryptographic Failures
- Injection
- Insecure Design
- Security Misconfiguration
- Vulnerable and Outdated Components
- Identification and Authentication Failures
- Software and Data Integrity Failures
- Security Logging and Monitoring Failures
- Server-Side Request Forgery (SSRF)
3. Penetration Testing Process
The penetration testing process typically involves the following steps:
- Planning and Preparation
- Information Gathering
- Threat Modeling
- Exploitation
- Post-Exploitation
- Reporting

4. Common Vulnerabilities
Here’s a brief overview of how to test for common OWASP Top 10 vulnerabilities:
4.1 Broken Access Control
Test for access controls using URL manipulation and checking user roles.
4.2 Cryptographic Failures
Use tools to check for weak encryption and insecure protocols.
4.3 Injection
Utilize payloads to test SQL Injection vulnerabilities.

5. Best Practices
Follow these best practices during penetration testing:
- Always get proper authorization before testing.
- Use a combination of automated and manual testing methods.
- Document everything thoroughly.
- Keep up to date with the latest vulnerabilities and exploits.
6. FAQ
What is penetration testing?
Penetration testing is an authorized simulated attack on a computer system to evaluate its security.
How often should penetration tests be conducted?
Penetration tests should be conducted at least annually and after any significant changes to the application.
What tools are commonly used for penetration testing?
Common tools include Burp Suite, OWASP ZAP, Metasploit, and Nmap.
