Skill Profile
Vulnerability Assessment
"The observable action of systematically identifying, classifying, and prioritising security vulnerabilities in systems, applications, and infrastructure — using automated scanning tools, manual testing techniques, and threat context — to produce an accurate risk-ordered remediation backlog for the organisation."
YOUR SKILLS
Problems This Skill Solves
- Organisations that do not know which of their systems are vulnerable to known exploits — systematic vulnerability scanning maps the attack surface and identifies every known vulnerable version, misconfiguration, and missing patch before attackers find them.
- Vulnerability backlogs so large that teams do not know where to start — risk-based prioritisation using CVSS scores, exploitability data, and asset criticality focuses remediation effort on the vulnerabilities that present the highest actual risk.
- Patches deployed without understanding their impact — vulnerability assessment context (what the vulnerability enables an attacker to do, which assets are affected) informs prioritisation and change management decisions.
- Security debt accumulating invisibly in development — integrating vulnerability scanning into CI/CD pipelines (DevSecOps) identifies vulnerabilities during development rather than after deployment when they are expensive to fix.

Cybersecurity / Technology / Finance
"If you patch everything with a critical CVSS score, you're doing vulnerability management correctly."
CVSS score measures the theoretical maximum severity of a vulnerability — it does not account for whether the vulnerability is actually exploitable in your environment (mitigating controls, network exposure, authentication requirements), whether public exploits exist, or how critical the affected asset is to your business. Risk-based vulnerability management that contextualises the CVSS score against these factors consistently produces better security outcomes per remediation unit of effort than simple CVSS-score prioritisation.
Research & Outlook
AI-assisted vulnerability prioritisation is improving triage accuracy — using exploit prediction scoring (EPSS) and threat intelligence to predict which vulnerabilities are most likely to be exploited in the near term. The expansion of the attack surface to include cloud infrastructure, containers, code dependencies (SCA), and AI models is increasing the scope of vulnerability assessment programmes. Continuous validation approaches (like breach and attack simulation tools) are complementing periodic scanning with real-time attack path monitoring.

Growth Path
Runs vulnerability scans using a tool like Nessus Essentials against a defined scope. Interprets scan results and understands CVSS severity ratings. Identifies the highest-risk findings and produces a basic remediation report. Understands the difference between a vulnerability (a weakness) and an exploit (a method of taking advantage of it).
Manages an enterprise vulnerability management programme — scanning, prioritising, tracking remediation, and reporting to leadership. Conducts manual validation of automated scan findings to eliminate false positives. Integrates vulnerability scanning into development pipelines for application security. Produces risk-based vulnerability reports that translate technical findings into business risk language.
Designs and leads the organisation's vulnerability management strategy — tool selection, scanning frequency, prioritisation framework, SLA setting, and exception management. Oversees penetration testing programmes. Contributes to CVE disclosure processes. Advises on vulnerability management in complex environments (OT/ICS, cloud-native, containerised). Builds DevSecOps vulnerability management capability.
How to Practise
- 1.Set up a vulnerable VM (Metasploitable, DVWA, Vulnhub machines) in a home lab and run a Nessus Essentials or OpenVAS scan against it — practise interpreting the results, understanding what each vulnerability enables, and planning remediation.
- 2.Complete OWASP Top 10 training using OWASP WebGoat or similar deliberately vulnerable web applications — understand each vulnerability class, how to identify it, and how to remediate it.
- 3.Practise risk-based vulnerability prioritisation — take a sample vulnerability scan report and rank the findings by actual risk (combining CVSS score, exploitability, asset criticality, and compensating controls) rather than just CVSS score.
- 4.Study the CVE database and NVD — learn how to read a CVE entry, understand the CVSS score components, and research whether a vulnerability has known public exploits.
How to Prove
- ·CompTIA PenTest+ or CEH (Certified Ethical Hacker) — certifications that include vulnerability assessment as a core component.
- ·GIAC GEVA (Enterprise Vulnerability Assessor) — specialist certification for vulnerability management programmes.
- ·Vulnerability management programme ownership — demonstrating responsibility for an organisation's vulnerability scanning and remediation tracking.
- ·Bug bounty programme credits — public evidence of vulnerability discovery in real production systems.
