The EDB Postgres Advanced Server must generate audit records when security objects are deleted.
The removal of security objects from the database/DBMS would seriously degrade a system's information assurance posture. If such an event occurs, it must be logged.Rule Medium Severity -

The EDB Postgres Advanced Server must generate audit records when unsuccessful attempts to execute privileged activities or other system-level access occur.
Without tracking privileged activity, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one. System documentation ...Rule Medium Severity -

The EDB Postgres Advanced Server must generate audit records for all direct access to the database(s).
In this context, direct access is any query, command, or call to the DBMS that comes from any source other than the application(s) that it supports. Examples would be the command line or a database...Rule Medium Severity -

The EDB Postgres Advanced Server must implement NIST FIPS 140-2 or 140-3 validated cryptographic modules to provision digital signatures.
Use of weak or untested encryption algorithms undermines the purposes of utilizing encryption to protect data. The application must implement cryptographic modules adhering to the higher standards ...Rule Medium Severity -

The EDB Postgres Advanced Server must off-load audit data to a separate log management facility; this must be continuous and in near real time for systems with a network connection to the storage facility and weekly or more often for stand-alone systems.
Information stored in one location is vulnerable to accidental or incidental deletion or alteration. Off-loading is a common process in information systems with limited audit storage capacity. Th...Rule Medium Severity -
