Log Review Tips
Critical systems require at least daily log review, however, what types of logs/activities should we pay attention to?
1. Consecutive login failure especially in non-office hour.
2. Login in non-office hour.
3. Authority change, addition and removal. Check them against with authorized application.
4. Any system administrator's activities
5. Any unknown workstation/server are plugged into the network?
6. Logs removal/log overwritten/log size is full
7. Pay more attention to the log reports after week-end and holiday
8. Any account unlocked/password reset by system administrators without authorized forms?
In fact, we are suffering various log format and standard from various systems even we are working in-house or act as a consultant. Why don't we produce a standard/guidelines to developer before they design the user administrative and audit trail functions to fulfill security control.
