Ubuntu 24.04 LTS must generate audit records when successful/unsuccessful attempts to use the fdisk command.

STIG ID: UBTU-24-900750  |  SRG: SRG-OS-000477-GPOS-00222 |  Severity: medium |  CCI: CCI-000172 |  Vulnerability Id: V-270815

Vulnerability Discussion

Without generating audit records 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).

Check

Verify Ubuntu 24.04 LTS is configured to audit the execution of the partition management program "fdisk" with the following command:

$ sudo auditctl -l | grep fdisk
-w /usr/sbin/fdisk -p x -k fdisk

If the command does not return a line, or the line is commented out, this is a finding.

Note: The "-k" allows for specifying an arbitrary identifier, and the string after it does not need to match the example output above.

Fix

Configure Ubuntu 24.04 LTS to audit the execution of the partition management program "fdisk".

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

-w /usr/sbin/fdisk -p x -k fdisk

To reload the rules file, issue the following command:

$ sudo augenrules --load
