Short answer
A vulnerability assessment identifies known weaknesses in systems, services or configurations and helps prioritise what should be fixed.
The assessment explains the findings, their relevance to your environment and the recommended actions.
What it can cover
Depending on the scope, a vulnerability assessment may cover:
- internet-facing systems and services
- internal networks and infrastructure
- cloud services and configuration exposure
- user device exposure
- patching and software versions
- common misconfigurations
- weak or unnecessary services
- remediation planning
The scope should match the reason for the assessment. A customer assurance request, Cyber Essentials Plus preparation and a broad internal security review may all need slightly different approaches.
Vulnerability assessment versus penetration testing
A vulnerability assessment and a penetration test are not the same thing.
A vulnerability assessment usually focuses on identifying and prioritising known weaknesses. A penetration test is more targeted and attempts to exploit weaknesses to demonstrate impact within agreed rules.
Both can be valuable. The right choice depends on your objective, maturity, budget and the assurance you need to provide.
For many organisations, a vulnerability assessment is a sensible first step because it can identify common issues quickly and help build a remediation plan.
What a useful report should include
A useful report should include more than severity scores.
It should explain:
- what was assessed
- what was found
- why the finding matters
- how likely exploitation may be in context
- which findings need urgent attention
- what can be planned
- what requires further investigation
- practical remediation guidance
The output should be understandable by both technical teams and decision makers.
Common findings
Common findings include outdated software, exposed services, weak configuration, unsupported systems, missing security headers, vulnerable web services, old remote access tools and unnecessary services left running.
Each finding needs to be assessed in the context of the affected system and the risk to your organisation.
How often should it be done?
The right frequency depends on the organisation and the systems involved.
A vulnerability assessment may be useful:
- before Cyber Essentials Plus
- after major infrastructure or cloud changes
- before a customer assurance review
- after onboarding a new supplier or service
- periodically as part of an ongoing security programme
