Title

The EDB Postgres Advanced Server must generate audit records showing starting and ending time for user access to the database(s). (Cat II impact)

Discussion

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.

Check Content

Execute the following SQL as the "enterprisedb" operating system user: > psql edb -c "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

Execute the following SQL as the "enterprisedb" operating system user: > psql edb -c "ALTER SYSTEM SET edb_audit_connect = 'all'" > psql edb -c "ALTER SYSTEM SET edb_audit_disconnect = '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.
