An overview of the importance of cyber security assessment and testing in identifying vulnerabilities and securing digital assets.
Introduction to Cyber Security Assessment and Testing
Designed as a quick‑reference guide for students, new analysts, or anyone needing a clear overview.
| Aspect | Description |
|---|---|
| Purpose | Identify weaknesses, measure risk, and verify that security controls work as intended. |
| Scope | Can cover networks, applications, cloud environments, endpoints, people, and processes. |
| Outcome | Actionable findings (e.g., “unpatched server”) plus recommendations and a prioritized remediation plan. |
| Frequency | One‑time (e.g., before a launch) or recurring (quarterly, annually, after major changes). |
| Type | Goal | Typical Methods | When to Use |
|---|---|---|---|
| Vulnerability Assessment (VA) | Catalog known weaknesses. | Automated scanners, asset inventory, CVE databases. | Regular baseline checks; large asset pools. |
| Penetration Testing (Pen‑Test) | Simulate real‑world attack to see if vulnerabilities can be exploited. | Manual exploitation, automated tools, social engineering. | Before release, after major changes, compliance requirements. |
| Red Team Exercise | Full‑scale adversary emulation (tactics, techniques, procedures). | Long‑duration attacks, physical/social vectors, stealth. | High‑value targets, maturity testing, executive buy‑in. |
| Blue Team Assessment | Evaluate detection and response capabilities. | SOC monitoring review, incident‑response drills, log analysis. | Ongoing operations, maturity assessments. |
| Purple‑Team Collaboration | Combine Red and Blue to improve both offense and defense. | Joint exercises, shared debriefs, tool‑chain integration. | Continuous improvement cycles. |
| Security Posture Review | Holistic view of policies, governance, and controls. | Interviews, documentation review, gap analysis. | Strategic planning, audit preparation. |
| Framework | Key Phases | Typical Deliverables |
|---|---|---|
| NIST SP 800‑115 (Technical Guide to Information Security Testing) | Planning → Discovery → Attack → Reporting | Test plan, evidence logs, risk rating. |
| OWASP Testing Guide (Web Apps) | Information Gathering → Threat Modeling → Vulnerability Identification → Exploitation → Reporting | OWASP Top 10 coverage matrix, proof‑of‑concept (PoC) scripts. |
| PTES (Penetration Testing Execution Standard) | Pre‑engagement → Intelligence Gathering → Threat Modeling → Vulnerability Analysis → Exploitation → Post‑exploitation → Reporting | Detailed scope, risk matrix, remediation checklist. |
| MITRE ATT&CK | Mapping of adversary techniques → Detection gap analysis → Mitigation planning | ATT&CK matrix heat map, detection coverage score. |
| ISO/IEC 27001 & 27002 | Control selection → Implementation → Monitoring → Review | Control effectiveness report, compliance gap analysis. |
