Discussion

For completeness of forensic analysis, it is necessary to track failed attempts to log on to the DBMS. While positive identification may not be possible in a case of failed authentication, as much information as possible about the incident must be captured.

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.
