Definition
Vulnerability analysis is the process of identifying, quantifying, and prioritizing weaknesses in a system or network. It involves systematically reviewing hardware, software, and configurations to discover potential security flaws that could be exploited by attackers. This proactive approach helps organizations understand their security posture and the potential impact of discovered vulnerabilities. By performing regular vulnerability analyses, teams can effectively manage risks and allocate resources to address the most critical issues first. For instance, a company might scan its web servers for outdated software versions, a common vulnerability. This differs from penetration testing, which actively attempts to exploit vulnerabilities, whereas analysis focuses on discovery and assessment. Vulnerability analysis is a core concept tested on CompTIA Security+, CySA+, and CISSP certifications.
