UBTU-18-010315 - The Ubuntu operating system must generate audit records for successful/unsuccessful uses of the su command.

Information

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

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

-a always,exit -F path=/bin/su -F perm=x -F auid>=1000 -F auid!=4294967295 -k privileged-priv_change

In order to reload the rules file, issue the following command:

# sudo augenrules --load

Note:
The "root" account must be used to view/edit any files in the /etc/audit/rules.d/ directory.
