Description
Without auditing the enforcement of access restrictions against changes to configuration, it would be difficult to identify attempted attacks and an audit trail would not be available for forensic investigation for after-the-fact actions. Enforcement actions are the methods or mechanisms used to prevent unauthorized changes to configuration settings. Enforcement action methods may be as simple as denying access to a file based on the application of file permissions (access restriction). Audit items may consist of lists of actions blocked by access restrictions or changes identified after the fact.

ℹ️ Check
Execute the following SQL as "enterprisedb" operating system user: > psql edb -c "SHOW edb_audit_statement" If the result is not "all" or if the current setting for this requirement has not been noted and approved by the organization in the system documentation, this is a finding.

✔️ Fix
Execute the following SQL as "enterprisedb" operating system user: > psql edb -c "ALTER SYSTEM SET edb_audit_statement = 'all'" > psql edb -c "SELECT pg_reload_conf()" or Update the system documentation to note the organizationally approved setting and corresponding justification of the setting for this requirement.
