Description
For completeness of forensic analysis, it is necessary to know how long a user's (or other principal's) connection to the DBMS lasts. This can be achieved by recording disconnections, in addition to logons/connections, in the audit logs. Disconnection may be initiated by the user or forced by the system (as in a timeout) or result from a system or network failure. To the greatest extent possible, all disconnections must be logged.

Execute the following SQL as enterprisedb: SHOW edb_audit_connect; 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 Text (F-14879r290290_fix)
Execute the following SQL as enterprisedb: ALTER SYSTEM SET edb_audit_connect = 'all'; ALTER SYSTEM SET edb_audit_disconnect = 'all'; SELECT pg_reload_conf(); or Update the system documentation to note the organizationally approved setting and corresponding justification of the setting for this requirement.
