The EDB Postgres Advanced Server must generate audit records when unsuccessful accesses to objects occur.

Without tracking all or selected types of access to all or selected objects (tables, views, procedures, functions, etc.), it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one.

In an SQL environment, types of access include, but are not necessarily limited to:

SELECT INSERT UPDATE DELETE EXECUTE

To aid in diagnosis, it is necessary to keep track of failed attempts in addition to the successful ones.

Execute the following SQL as the "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.

Execute the following SQL as the "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.
