## Ensure Synchronized System Time

Ensure all servers in your environment are synchronized using a network time protocol (NTP). This is critical for authentication tokens (OTP, JWT) and log correlation.

**Details:**
- Configure NTP/Chrony on all production servers.
- Monitor time synchronization offset.
- Important for TOTP (MFA) and token expiry checks.

**Tools:** NTP, Chrony, CloudWatch Time Sync
