Common Auditor Questions & Answers

Q: How do you ensure log completeness?

A: Multi-layered validation:

• Daily automated verification of log counts
• Gap detection algorithms check for missing dates
• API endpoints provide real-time status monitoring
• Manual verification procedures for incident response

Q: What happens if the automated system fails?

A: Comprehensive backup procedures:

• Slack alerts notify team within 2-3 minutes
• Manual execution procedures documented and tested
• Historical shipping command can recover missed days
• Multiple monitoring layers prevent silent failures

Q: How is access to logs controlled?

A: Multi-factor access controls:

• AWS IAM with least-privilege policies
• GitHub repository access controls
• MFA required for all administrative access
• Quarterly access reviews and credential rotation

Q: How do you protect sensitive data in logs?

A: Data protection measures:

• No PII stored in plain text (user IDs only)
• Encryption at rest (AES-256) and in transit (TLS)
• Access-controlled IP addresses in logs
• Data classification and handling procedures

Q: What's your incident response process?

A: Structured response procedures:

• Automated alerting within 5 minutes
• 30-minute investigation and containment SLA
• 2-hour resolution and documentation SLA
• Post-incident review and improvement process
