Description
Reconstruction of harmful events or forensic analysis is not possible if audit records do not contain enough information. At a minimum, the organization must audit the full-text recording of privileged commands. The organization must maintain audit trails in sufficient detail to reconstruct events to determine the cause and impact of compromise.

Check Text ( C-76893r2_chk )
Verify the SUSE operating system generates an audit record for all uses of the "ssh-agent" command. Check that the following command call is being audited by performing the following command on the system rules in "/etc/audit/audit.rules": # sudo grep -i ssh-agent /etc/audit/audit.rules -a always,exit -F arch=32 path=/usr/bin/ssh-agent -F perm=x -F auid>=500 -F auid!=4294967295 -k privileged-ssh-agent -a always,exit -F arch=64 path=/usr/bin/ssh-agent -F perm=x -F auid>=500 -F auid!=4294967295 -k privileged-ssh-agent If the command does not return any output, this is a finding.

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

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

# sudo grep -i ssh-agent /etc/audit/audit.rules

-a always,exit -F arch=32 path=/usr/bin/ssh-agent -F perm=x -F auid>=500 -F auid!=4294967295 -k privileged-ssh-agent

If the command does not return any output, this is a finding.

Fix Text (F-83979r2_fix)
Configure the SUSE operating system to generate an audit record for all uses the "ssh-agent" command. Add or update the following rule to "/etc/audit/audit.rules": -a always,exit -F arch=32 path=/usr/bin/ssh-agent -F perm=x -F auid>=500 -F auid!=4294967295 -k privileged-ssh-agent -a always,exit -F arch=64 path=/usr/bin/ssh-agent -F perm=x -F auid>=500 -F auid!=4294967295 -k privileged-ssh-agent The audit daemon must be restarted for any changes to take effect.
