Fix Recommendation

Modify and/or configure PostgreSQL and related applications and tools so that users are always required to reauthenticate when changing role or escalating privileges.

To make a single user re-authenticate, the following must be present:

SELECT pg_terminate_backend(pid) FROM pg_stat_activity WHERE user='<username>'

To make all users re-authenticate, the following must be present:

SELECT pg_terminate_backend(pid) FROM pg_stat_activity WHERE user LIKE '%'

Check Contents

Determine all situations where a user must re-authenticate. Check if the mechanisms that handle such situations use the following SQL:

To make a single user re-authenticate, the following must be present:

SELECT pg_terminate_backend(pid) FROM pg_stat_activity WHERE user='<username>'

To make all users re-authenticate, run the following:

SELECT pg_terminate_backend(pid) FROM pg_stat_activity WHERE user LIKE '%'

If the provided SQL does not force re-authentication, this is a finding.
