PCI Requirement 10.2 – Implement Automated Audit Trails for all System Components to Reconstruct the Events
What Do I Log?
Because PCI Requirement 10 requires that logging mechanisms be enabled, we often hear clients ask, “What do I log?” The PCI DSS gives us specific insight into which events need to be logged so that audit trails can provide a history to help identify and trace malicious activities. PCI Requirement 10.2 requires that organizations implement automated audit trails for all system components to reconstruct the following events:
- All individual user accesses to cardholder data
- All actions taken by any individual with root or administrative privileges.
- Access to all audit trails.
- Invalid logical access attempts.
- Use of and changes to identification and authentication mechanisms — including, but not limited to, creation of new accounts and elevation of privileges — and all changes, additions, or deletions to accounts with root or administrative privileges.
- Initialization, stopping, or pausing of the audit logs.
- Creation and deletion of system-level objects.

The following topics are those items that need to be logged.
