Title
The SUSE operating system must generate audit records for all uses of the setfacl command. (Cat II impact)
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). Satisfies: SRG-OS-000037-GPOS-00015, SRG-OS-000062-GPOS-00031, SRG-OS-000392-GPOS-00172, SRG-OS-000462-GPOS-00206, SRG-OS-000471-GPOS-00215
Check Content
Verify the SUSE operating system generates an audit record for all uses of the "setfacl" command. Check that the command is being audited by performing the following command: > sudo auditctl -l | grep -w '/usr/bin/setfacl' -a always,exit -S all -F path=/usr/bin/setfacl -F perm=x -F auid>=1000 -F auid!=-1 -k prim_mod If the command does not return any output, this is a finding. Note: The "-k" allows for specifying an arbitrary identifier. The string following "-k" does not need to match the example output above.
Fix Text
Configure the SUSE operating system to generate an audit record for all uses of the "setfacl" command. Add or update the following rules in the "/etc/audit/rules.d/audit.rules" file: -a always,exit -F path=/usr/bin/setfacl -F perm=x -F auid>=1000 -F auid!=4294967295 -k prim_mod To reload the rules file, restart the audit daemon > sudo systemctl restart auditd.service or issue the following command: > sudo augenrules --load
