Vulnerability Management - OWASP Top 10
Introduction
Vulnerability Management is a crucial aspect of application security, particularly in the context of the OWASP Top 10, which outlines the most critical security risks to web applications. This lesson will cover the essential concepts, processes, and best practices for effective vulnerability management.
Key Concepts
What is Vulnerability Management?
Vulnerability management is a continuous process of identifying, classifying, remediating, and mitigating vulnerabilities in software and hardware systems.
Common Vulnerabilities (OWASP Top 10)
- Injection
- Broken Authentication
- Sensitive Data Exposure
- XML External Entities (XXE)
- Broken Access Control
- Security Misconfiguration
- XSS (Cross-Site Scripting)
- Insecure Deserialization
- Using Components with Known Vulnerabilities
- Insufficient Logging & Monitoring
Vulnerability Management Process
The vulnerability management process can be broken down into the following steps:
- Identification
- Prioritization
- Remediation
- Verification
- Monitoring

Best Practices
Effective Vulnerability Management
- Conduct regular vulnerability scans and assessments.
- Utilize automated tools for vulnerability discovery.
- Implement a risk-based approach to prioritize vulnerabilities.
- Maintain an up-to-date inventory of assets.
- Ensure timely patching and remediation of identified vulnerabilities.
FAQ
What tools can be used for vulnerability management?
Common tools include Nessus, Qualys, Rapid7, and OWASP ZAP.
How often should vulnerability scans be performed?
Vulnerability scans should be conducted at least quarterly, or after significant changes to the environment.
What is the difference between vulnerability assessment and penetration testing?
Vulnerability assessment identifies and classifies vulnerabilities, while penetration testing attempts to exploit those vulnerabilities to determine their impact.
