Security Audits is a free Cyber Security Academy lesson on CoddyKit — lesson 2 of 4. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the Cyber Security Academy learning path, one of 4 lessons in the course, and your progress syncs across the web and the CoddyKit app.
What Is a Security Audit
A security audit is a systematic assessment of how well an organization meets its security controls and policies. It compares the actual state against a defined standard and documents the gaps.
Audits assess controls; they do not, by themselves, fix problems.
Audit vs Pen Test vs Assessment
These terms overlap but differ:
- Audit: checks controls against a standard, with evidence.
- Penetration test: actively exploits weaknesses to prove impact.
- Risk assessment: estimates likelihood and impact of threats.
Internal vs External Audits
Audits come from two sources:
- Internal: run by your own team for continuous assurance and readiness.
- External: run by independent auditors, required for certification and to give stakeholders confidence.
The Audit Lifecycle
A typical audit follows clear phases:
- Planning: define scope and objectives.
- Fieldwork: gather and test evidence.
- Reporting: document findings and severities.
- Remediation: fix gaps and verify.
Defining Scope and Objectives
Scope keeps the audit focused and bounded. Specify which systems, locations, processes, and time period are included.
Clear objectives (e.g. validate ISO 27001 Annex A controls) tell auditors what evidence to collect and what good looks like.
Gathering Evidence
Auditors collect proof that controls exist and operate:
- Configuration exports and screenshots.
- Logs and access reviews.
- Policies and signed approvals.
- Interviews with control owners.
Testing Controls
Auditors test in two ways:
- Design: is the control capable of meeting its objective?
- Operating effectiveness: did it actually work over the period?
Sampling is common: examine a representative subset of records rather than all of them.
Findings and Severity
Each gap becomes a finding, rated by risk. A consistent scale helps prioritize.
- Critical / High: urgent, exploitable, or compliance-blocking.
- Medium: should be fixed soon.
- Low / Observation: minor or hardening suggestion.
Remediation and Tracking
Findings must lead to action. Track each one with an owner, a plan, and a due date in a remediation register.
- Assign accountability.
- Set realistic deadlines by severity.
- Verify the fix (re-test) before closing.
Auditor Independence
An auditor should not assess work they performed themselves, to avoid conflicts of interest. Independence (especially for external audits) is what makes the result credible to customers and regulators.
Continuous Auditing
Modern programs supplement periodic audits with continuous monitoring: automated checks that flag drift from a secure baseline in near real time, reducing surprises at the formal audit.

Distinguish an audit from a penetration test.
Recap
Security audits assess how well controls meet a standard:
- Audits differ from pen tests and risk assessments.
- Follow the lifecycle: plan, fieldwork, report, remediate.
- Gather evidence, test design and operation, rate findings.
- Track remediation and keep auditors independent.
