Security
The purpose of analyzing the audit log is to understand the following and im-
plement countermeasures:
- Whether or not data was accessed or tampered with
- Subject of attack
- Details of attack
- Results of attack
For specific analysis methods, see the next page.
Specify unauthorized actions: password authentication
If logs have NG as the result of password authentication (action: 01, 02, 11,
16), items protected by passwords may have been attacked.
- Failed password authentication (NG) log entries specify who made the
operation, and show if unauthorized actions were made when password
authentication failed.
- Even if password authentication succeeded (OK), it shows whether a le-
gitimate user created the action. You need to check carefully when suc-
cessful authentication occurs after series of failures especially during
times other than normal operating hours.
