Vulnerability discussion

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.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 any use of the "sudo" 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 sudo /etc/audit/audit.rules -a always,exit -F -arch=b32 path=/usr/bin/sudo -F perm=x -F auid>=500 -F auid!=4294967295 -k privileged-sudo -a always,exit -F -arch=b64 path=/usr/bin/sudo -F perm=x -F auid>=500 -F auid!=4294967295 -k privileged-sudo If the command does not return any output, this is a finding.

Fix text

Configure the SUSE operating system to generate an audit record for all uses of the "sudo" command. Add or update the following rule to "/etc/audit/audit.rules": -a always,exit -F -arch=b32 path=/usr/bin/sudo -F perm=x -F auid>=500 -F auid!=4294967295 -k privileged-sudo -a always,exit -F -arch=b64 path=/usr/bin/sudo -F perm=x -F auid>=500 -F auid!=4294967295 -k privileged-sudo The audit daemon must be restarted for any changes to take effect.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
