Time Synchronization
Description
Time synchronization must be implemented across all system components to ensure consistent timestamps in audit logs.
⚠️ Risk Impact
Time drift across systems makes log correlation impossible. Forensic investigation requires consistent timestamps across cloud, application, and infrastructure layers.
🔍 How EchelonGraph Detects This
EchelonGraph's Tier 1 Cloud Scanner automatically checks for this condition across all connected cloud accounts. Violations are flagged as medium-severity findings with remediation guidance.
🔧 Remediation
Use cloud-native NTP. Verify time drift <1 second across all systems. Monitor + alert on drift >5 seconds. Document the time source.
💀 Real-World Attack Scenario
A merchant's investigation of a breach required correlating events across 4 systems. Time drift averaged 7 minutes between systems. Forensic timeline reconstruction took 3× longer than necessary; some causal chains couldn't be established due to ambiguous ordering. The investigation extended 11 days.
💰 Cost of Non-Compliance
Forensic investigation cost increases 3× without time sync (Mandiant M-Trends 2024).
📋 Audit Questions
- 1.Time-sync source?
- 2.Drift tolerance?
- 3.Monitoring for drift?
- 4.Last drift event?
🎯 MITRE ATT&CK Mapping
⚡ Common Pitfalls
- ⛔Default NTP not configured on cloud instances
- ⛔No monitoring for time drift
- ⛔Time zones unmanaged (UTC vs local creates confusion)
📈 Business Value
Time sync is foundational to incident forensics + audit.
