Information

The operating system must generate audit records for successful/unsuccessful uses of the su command.

GROUP ID: V-260622
RULE ID: SV-260622r958446

Without generating audit records that are specific to the security and mission needs of the organization, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one.

Audit records can be generated from various components within the information system (e.g., module or policy filter).

Solution

Configure the audit system to generate audit records when successful/unsuccessful attempts to use the "su" command occur.

Add or modify the following line in the "/etc/audit/rules.d/stig.rules" file:

-a always,exit -F path=/bin/su -F perm=x -F auid>=1000 -F auid!=unset -k privileged-priv_change

To reload the rules file, issue the following command:

$ sudo augenrules --load

Note: The "-k " at the end of the line gives the rule a unique meaning to help during an audit investigation. The does not need to match the example above.
