Vulnerability assessment

Identifying and classifying security vulnerabilities in networks, systems and applications and mitigating or eliminating their impact.

Activities may include — but are not limited to:

- cataloguing and classifying information and technology resources (assets and capabilities) to support vulnerability assessment
- assigning quantifiable value, rank order and importance to information and technology resources
- identifying and analysing the vulnerabilities of each resource — manually or using automated tools and information sources
- prioritising, scoring and ranking the risk associated with vulnerabilities
- business impact assessment
- mitigating or eliminating the vulnerabilities.

Vulnerability assessment tools include web application scanners, protocol scanners and network scanners.
