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-000062-GPOS-00031, SRG-OS-000004-GPOS-00004, SRG-OS-000037-GPOS-00015, SRG-OS-000042-GPOS-00020, SRG-OS-000062-GPOS-00031, SRG-OS-000304-GPOS-00121, SRG-OS-000392-GPOS-00172, SRG-OS-000462-GPOS-00206, SRG-OS-000470-GPOS-00214, SRG-OS-000471-GPOS-00215, SRG-OS-000239-GPOS-00089, SRG-OS-000240-GPOS-00090, SRG-OS-000241-GPOS-00091, SRG-OS-000303-GPOS-00120, SRG-OS-000304-GPOS-00121, SRG-OS-000466-GPOS-00210, SRG-OS-000476-GPOS-00221

Check Content

Verify RHEL 8 generates audit records for all account creations, modifications, disabling, and termination events that affect "/etc/shadow".

Check the auditing rules in "/etc/audit/audit.rules" with the following command:

$ sudo grep /etc/shadow /etc/audit/audit.rules

-w /etc/shadow -p wa -k identity

If the command does not return a line, or the line is commented out, this is a finding.

Fix Text

Configure RHEL 8 to generate audit records for all account creations, modifications, disabling, and termination events that affect "/etc/shadow".

Add or update the following file system rule to "/etc/audit/rules.d/audit.rules":

-w /etc/shadow -p wa -k identity

The audit daemon must be restarted for the changes to take effect.
