Ubuntu 22.04 LTS must generate audit records for successful/unsuccessful uses of the su command.

An XCCDF Rule

Description

<VulnDiscussion>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).</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

Configure Ubuntu 22.04 LTS 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 <keyname>" at the end of the line gives the rule a unique meaning to help during an audit investigation. The <keyname> does not need to match the example above.
