Title
Successful/unsuccessful modifications to the tallylog file must generate an audit record. (Cat II impact)
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-000042-GPOS-00020, 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 Ubuntu operating system generates an audit record when successful/unsuccessful modifications to the "tallylog" file occur. Check that the following calls are being audited by performing the following command to check the file system rules in "/etc/audit/audit.rules": # sudo grep -w tallylog /etc/audit/audit.rules -w /var/log/tallylog -p wa -k logins If the command does not return a line, or the line is commented out, this is a finding.
Fix Text
Configure the audit system to generate an audit event for any successful/unsuccessful 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. To restart the audit daemon, run the following command: # sudo systemctl restart auditd.service
