Where appropriate, procedures shall incorporate segregation of duties.

Examples:

  • Requester vs approver
  • Developer vs production approver
  • Administrator vs reviewer

  • MFA
  • Least privilege
  • Authorization
  • Encryption
  • Logging
  • Monitoring
  • Backup
  • Change control
  • Data classification
  • Secure disposal
  • Evidence preservation

Security requirements should be incorporated into operational steps rather than treated as separate optional activities.

Examples:

  • Access requests
  • Approval records
  • Change tickets
  • Backup logs
  • Restore test results
  • Vulnerability reports

Acknowledgement should not be treated as evidence that the procedure is actually being followed.

Operational compliance should be independently verified where appropriate.


31. Procedure Compliance Monitoring

The organization should periodically verify that procedures are being followed.

Methods may include:

  • Sampling
  • Internal audit
  • Control testing

44. AWS SaaS Startup Example

Scenario

A SaaS startup operates its production application in AWS.

The organization maintains the following operating procedures:

ProcedurePurpose
AWS Access ManagementProvision and remove cloud access
Production DeploymentSecure production releases
Backup & RestoreProtect and recover customer data
Vulnerability ManagementIdentify and remediate vulnerabilities
Security MonitoringMonitor security events
Incident ResponseRespond to security incidents
Emergency AccessManage exceptional administrative access
Supplier Security ReviewAssess critical suppliers

Example

For Production Deployment, the procedure may require:

  1. Change request created.
  2. Developer completes testing.
  3. Code review completed.
  4. Security checks completed where required.
  5. Production approval obtained.
  6. Deployment performed.
  7. Deployment recorded.
  8. Monitoring performed.
  9. Rollback initiated if required.

Evidence

  • Change ticket
  • Code review
  • CI/CD record
  • Approval
  • Deployment log
  • Monitoring evidence

Audit Trail

Approved Procedure → Authorized User → Required Steps → Security Controls → Operational Evidence → Review → Improvement


45. Startup-Friendly Model

A startup should not create hundreds of procedures simply to satisfy an audit.

Start with procedures for activities that are:

High Risk

  • Production access
  • Privileged access
  • Incident response
  • Backup and recovery
  • Security monitoring
  • Vulnerability management
  • Production deployment

High Frequency

  • User onboarding
  • Access provisioning
  • Access removal
  • Change management
  • Security alert handling

High Dependency

  • AWS operations
  • SaaS providers
  • Payment systems
  • Critical suppliers

High Compliance Impact

  • Customer data handling
  • Privacy
  • Security incidents
  • Data retention
  • Contractual requirements

46. Common Mistakes

Avoid:

  • Creating procedures nobody follows
  • Writing procedures only for audit purposes
  • Making procedures unnecessarily complex
  • Failing to assign an owner
  • Allowing outdated versions to remain in use
  • Failing to define evidence
  • Failing to update procedures after technology changes
  • Creating procedures without considering actual workflows
  • Ignoring emergency scenarios
  • Failing to train relevant personnel
  • Treating acknowledgement as proof of compliance
  • Failing to test critical procedures
  • Not documenting deviations
  • Maintaining duplicate or conflicting procedures

48. ISO/IEC 27001 Connection

Documented operating procedures support the organization’s ability to consistently perform information-security and operational activities in accordance with its ISMS requirements.

The organization should determine which procedures are necessary based on:

  • ISMS scope
  • Information-security risks
  • Business processes
  • Applicable controls
  • Legal and regulatory requirements
  • Customer requirements
  • Contractual obligations
  • Technology
  • Operational complexity
  • Business continuity requirements

A Documented Operating Procedures Policy is not itself a universally prescribed ISO/IEC 27001 form or mandatory document title.

ISO/IEC 27001 does not require an organization to document every operational activity. Documentation should be proportionate to the organization’s needs and risk. The organization should retain appropriate documented information and evidence necessary to demonstrate that relevant processes and controls are operating as intended.


49. Audit Evidence Checklist

For sampled operating procedures, the organization should be able to demonstrate:

☐ Procedure identified
☐ Business/security need established
☐ Owner assigned
☐ Current version available
☐ Approval recorded
☐ Effective date recorded
☐ Relevant personnel have access
☐ Relevant personnel trained where required
☐ Procedure actually used
☐ Operational evidence exists
☐ Changes controlled
☐ Periodic review completed
☐ Deviations managed
☐ Findings tracked
☐ Corrective actions completed where required


50. Final Operating Procedure Audit Trail

For every significant operational activity, the organization should be able to demonstrate:

What activity needs to be performed?
Why does it require a documented procedure?
Who owns the procedure?
Who is authorized to perform it?
What steps must be followed?
What security controls apply?
What evidence is generated?
How is the procedure kept current?
What happens when the procedure cannot be followed?
How is effectiveness verified?
How are lessons learned incorporated?

Final Principle

Documented operating procedures should not exist simply to satisfy an audit. They should provide clear, repeatable, secure instructions for performing important activities and create reliable evidence that the organization’s security controls are operating in practice.
