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 legitimate

user created the action. You need to check carefully when successful

authentication occurs after series of failures especially during times other than

normal operating hours.

Specify unauthorized actions: actions other than password

authentication under security

All operation results other than password authentication will be indicated as

successful (OK), so determine if there were any unauthorized actions by ID and

action.

• Since you cannot specify what was attacked only with an ID, you need to see the

action and the table on the previous page to determine whether unauthorized

actions were made on a personal box or secure box.

• Check the time, and see if the user who operated the specific subject made any

unauthorized actions.

(Example)

If a document saved in a box was printed using fraudulent authorization, the

following audit log entry will be created.

1. Password authentication for the box:

Action = 11

ID = Box that authentication was made

Result = OK/NG

2. Access to the document in the box:

Action = 13

ID = Box that authentication was made

Check the date and time the above operation occurred, and see if the operation on

the document in the personal box or secure box was made by a legitimate box

user.

Actions to take if unauthorized operations are found

• If it's found that a password has been leaked after analyzing the audit log, change

the password immediately.

• It's possible that a password may have been tampered with and legitimate users

cannot access a box. The machine manager must contact the user to confirm the

situation, and if that's the case, the machine manager must change the password

and delete the data saved in the box.

• If you cannot find documents that should be in a box or if you find a document with

changed content, unauthorized actions may have occurred. Similar

countermeasures are needed.
