Table of items saved in audit log

*1

: Audit log ID is saved as user ID when user authentication is successfully made, or when password incon-

formity occurs with a registered user name.

*2

: Audit log ID is saved as unregistered user ID when authentication failure occurs with an unregistered user

name.

The purpose of analyzing the audit log is to understand the following and implement countermeasures:

-

Whether or not data was accessed or tampered with

-

Subject of attack

-

Details of attack

-

Result of attack

For specific analysis methods, refer to the following description.

Specifying unauthorized actions: password authentication

If logs have NG as the result of password authentication (action: 01, 02, 11), items protected by passwords
may have been attacked.

-

Failed password authentication (NG) log entries specify who made the operation, and show if unauthor-
ized actions were made when password authentication failed.

-

Even if password authentication succeeded (OK), you may need to check whether a legitimate user cre-
ated the action. Careful check is recommended especially when successful authentication occurs after
series of failures, or for those made during times other than normal operating hours.

No.
