Vulnerability Discussion

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).

Check

Verify the SUSE operating system generates an audit record for all uses of the "passmass" command.

Check that the following command call is being audited by performing the following command to check the file system rules in "/etc/audit/audit.rules":

# sudo grep -i passmass /etc/audit/audit.rules

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

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

Fix

Configure the SUSE operating system to generate an audit record for all uses of the "passmass" command.

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

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

The audit daemon must be restarted for the changes to take effect.

# sudo systemctl restart auditd.service
