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).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, SRG-OS-000473-GPOS-00218

Check content

Verify the SUSE operating system generates an audit record when all modifications to the "tallylog" file occur. 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 tallylog /etc/audit/audit.rules -w /var/log/tallylog -p wa -k logins 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 any all modifications to the "tallylog" file occur. Add or update the following rules in the "/etc/audit/audit.rules" file: -w /var/log/tallylog -p wa -k logins The audit daemon must be restarted for the changes to take effect. # sudo systemctl restart auditd.service

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.
