security audit log

[Former Member]

Hi,

We are monitoring security audit log and receiving the events "In program (event id:BUZ) " and "field content changed (event id:CUL)". Please provide the details about these events

Hello,

looks to me that someone changed a value in a debugging session. As this is critical from security point of view it is usually logged in the Security Audit Log.

I agree with your conclusion.

Refer to SAP Note 539404 for details.

Hi,

why these events are critical?

what is " In program (event id:BUZ)" ? Is it indicates the execution?

I have not get the correct idea about these events

Hello,

changing a field value in a debugging session can be used, for example, to bypass authorization checks.

Changing the value of SY-SUBRC to 0 after an AUTHORITY-CHECK statement would allow the program to continue even if the necessary authorization is not given. Self-assignment of SAP_ALL would also be possible. Therefore it is critical and to be logged in the Security Audit Log.
