1. Purpose
The Corrective Action Tracker provides a central record for tracking actions identified from information security incidents, investigations, audits, risk assessments, security reviews, vulnerability assessments, supplier reviews, and management reviews.
The tracker ensures that corrective actions are:
- Clearly defined
- Assigned to an accountable owner
- Prioritised according to risk
- Given realistic target dates
- Supported by evidence
- Monitored until completion
- Independently verified where appropriate
- Formally closed
A corrective action should address the underlying cause or control weakness, not simply record that an immediate incident-response activity was completed.

8. Corrective vs Immediate Action
| Type | Description | Completed? |
|---|---|---|
| Immediate Correction | Action taken to address the current problem | Yes/No |

Yes / No
Effectiveness Review Notes
17. Overdue Action Management
| Action ID | Owner | Due Date | Days Overdue | Reason | Escalated? | New Date |
|---|---|---|---|---|---|---|
Escalation Triggers
Consider escalation when:
- Critical/high-risk actions become overdue
- The same action is repeatedly delayed
- Compensating controls are insufficient
- Customer or regulatory exposure remains
- Risk exceeds accepted tolerance
- The action owner cannot complete the action
- Dependencies remain unresolved
18. Blocked Actions

19. Risk Acceptance
If a corrective action cannot be implemented within the required timeframe, the organisation should determine whether the remaining risk is acceptable.
Risk Acceptance Required?
Yes / No

Expiry/Review Date
Risk acceptance should not be used simply to avoid implementing an important corrective action.
20. Corrective Action Closure
Closure Criteria
☐ Action implemented
☐ Root cause addressed
☐ Required evidence collected
☐ Evidence reviewed
☐ Control tested where appropriate
☐ Effectiveness assessed
☐ Residual risk assessed
☐ Supporting documentation updated
☐ Related risk register updated
☐ Related incident/audit record updated
☐ No further action required
☐ Closure approved
Closure Decision
☐ Closed
☐ Closed – Risk Accepted
☐ Closed – Compensating Control
☐ Reopened
☐ Further Action Required

21. Management Review
Corrective actions should be periodically reviewed by management or the appropriate security/compliance owner.

22. Corrective Action Metrics
Track trends rather than only individual actions.
| Metric | Result |
|---|---|
| Total Open Actions | |
| New Actions This Period | |
| Closed Actions This Period | |
| Overdue Actions | |
| Critical Actions Open | |
| High-Risk Actions Open | |
| Average Closure Time | |
| Reopened Actions | |
| Risk Accepted Actions | |
| Repeated Findings |
Useful Trend Questions
- Are corrective actions being closed on time?
- Are the same findings recurring?
- Are high-risk actions receiving appropriate attention?
- Are actions being closed based on evidence?
- Are root causes being addressed?
- Are incidents generating meaningful security improvements?
23. Recurring Finding Analysis
Repeated findings may indicate a systemic weakness.
| Finding | Previous Occurrence | Current Occurrence | Root Cause | Pattern | Additional Action |
|---|---|---|---|---|---|
Recurring Issue Identified?
Yes / No
Management Attention Required?
Yes / No
24. Example — AWS SaaS Startup
Finding
A security incident identified that an AWS access key belonging to a developer had been exposed.
Immediate Action
The exposed key was disabled and active sessions were reviewed.
Root Cause
The development process allowed credentials to be handled outside the approved secrets-management mechanism.
Corrective Action
Implement centralised secrets management and automated credential scanning across source-code repositories and CI/CD pipelines.
Owner
Engineering Lead
Priority
High
Evidence
- Secrets-management configuration
- Repository scanning results
- CI/CD configuration
- Test alert
- Updated developer procedure
Verification
Security team confirms that:
- New credentials are stored through the approved mechanism.
- Repository scanning is active.
- Test credentials trigger the expected alert.
- Developers cannot bypass the approved process without an approved exception.
Closure
The action is closed only after implementation evidence and effectiveness have been reviewed.

Corrective Action Defined

26. Relationship With Other ISMS Records
Corrective actions may originate from or feed into:
Incident
→ Incident Investigation
→ Root Cause
→ Corrective Action
→ Risk Assessment
→ Risk Treatment
→ Verification
→ Closure
Similarly:
Internal Audit
→ Finding
→ Corrective Action
→ Evidence
→ Effectiveness Review
→ Closure
And:
Risk Assessment
→ Risk
→ Treatment Decision
→ Action
→ Implementation
→ Residual Risk
→ Review
This creates a traceable relationship across the ISMS.
27. Audit Evidence Trail
A complete corrective action record should demonstrate:
Finding Identified
→ Evidence Recorded
→ Root Cause Analysed
→ Risk Assessed
→ Corrective Action Defined
→ Owner Assigned
→ Due Date Established
→ Action Implemented
→ Evidence Collected
→ Implementation Verified
→ Effectiveness Reviewed
→ Residual Risk Assessed
→ Management Review
→ Action Closed
28. ISO 27001 Connection
The Corrective Action Tracker supports the organisation’s process for addressing identified issues and improving the effectiveness of the information security management system.
It can be used to track actions arising from:
- Information security incidents
- Internal audits
- External audits
- Risk assessments
- Security assessments
- Vulnerability assessments
- Penetration testing
- Supplier assessments
- Management reviews
- Customer findings
- Compliance assessments
- Security monitoring
The organisation should determine the appropriate action, ownership, priority, verification method, and evidence based on the nature and risk of the finding.
29. Startup Implementation Approach
A startup can maintain one central corrective-action tracker rather than creating separate trackers for every security process.
For example:
| Source | Action | Owner | Priority | Due | Status |
|---|---|---|---|---|---|
| Incident | Rotate exposed credentials | Engineering | High | Closed | |
| VAPT | Fix critical vulnerability | Engineering | Critical | In Progress | |
| Internal Audit | Complete access review | IT | Medium | Open | |
| Risk Assessment | Enable additional monitoring | Security | High | Open | |
| Supplier Review | Obtain missing evidence | Procurement | Medium | Closed |
The key principle is:
One Finding → One Owner → One Due Date → One Evidence Trail → One Verification Decision.
Final Principle
Identify the Problem + Find the Root Cause + Assess the Risk + Assign Ownership + Define the Action + Set the Deadline + Implement + Verify Effectiveness + Track Residual Risk + Close With Evidence.
