Evidence Collection

Overview

Evidence includes configuration snapshots, drift history, change logs, compliance reports, and remediation records. This page explains how evidence is collected, stored, and used during audits.

Types of Evidence

• Configuration Snapshots – Point‑in‑time captures of configuration values.
• Drift History – Records of deviations from baselines.
• Change Logs – Documentation of approved and unapproved changes.
• Compliance Reports – Framework‑specific reports (SOC 2, ISO 27001, PCI DSS).
• Remediation Records – Proof that misconfigurations were corrected.
• Access Logs – Evidence of identity and permission changes.
• Audit Logs – System activity logs used for investigations.

Evidence Collection Workflow

1. Capture configuration snapshots
2. Record drift events and timestamps
3. Store change logs from configuration management systems
4. Generate compliance reports
5. Document remediation actions
6. Package evidence for auditors

Evidence Storage Requirements

• Store evidence in a secure, centralized repository
• Ensure evidence is immutable or version‑controlled
• Restrict access to authorized personnel
• Encrypt evidence at rest and in transit
• Retain evidence according to compliance requirements

Preparing Evidence for Audits

• Organize evidence by control or requirement
• Verify evidence completeness and accuracy
• Ensure remediation records are included
• Provide auditors with clear mapping documents
• Package evidence into a single audit bundle

Frequently Asked Questions

What is evidence collection?

Evidence collection gathers configuration snapshots, drift history, change logs, and compliance reports used to prove alignment with baselines and standards.

Why is evidence important for audits?

Auditors require evidence to verify secure configuration, change control, drift remediation, and compliance.

How long should evidence be retained?

Evidence retention varies by framework, typically 1–7 years depending on policy and regulatory requirements.
