EnterpriseDB Postgres Advanced Server (EPAS) Security Technical Implementation Guide
Rules, Groups, and Values defined within the XCCDF Benchmark
-
The EDB Postgres Advanced Server must prohibit user installation of logic modules (stored procedures, functions, triggers, views, etc.) without explicit privileged status.
Allowing regular users to install software without explicit privileges creates the risk that untested or potentially malicious software will be installed on the system. Explicit privileges (escalat...Rule Medium Severity -
The EDB Postgres Advanced Server must require users to reauthenticate when organization-defined circumstances or situations require reauthentication.
The DOD standard for authentication of an interactive user is the presentation of a Common Access Card (CAC) or other physical token bearing a valid, current, DOD-issued Public Key Infrastructure (...Rule Medium Severity -
The EDB Postgres Advanced Server must only accept end entity certificates issued by DOD PKI or DOD-approved PKI Certification Authorities (CAs) for the establishment of all encrypted sessions.
Only DOD-approved external PKIs have been evaluated to ensure that they have security controls and identity vetting procedures in place which are sufficient for DOD systems to rely on the identity ...Rule Medium Severity -
The EDB Postgres Advanced Server must implement cryptographic mechanisms preventing the unauthorized disclosure of organization-defined information at rest on organization-defined information system components.
DBMSs handling data requiring data at rest protections must employ cryptographic mechanisms to prevent unauthorized disclosure and modification of the information at rest. These cryptographic mecha...Rule Medium Severity -
When invalid inputs are received, the EDB Postgres Advanced Server must behave in a predictable and documented manner that reflects organizational and system objectives.
A common vulnerability is unplanned behavior when invalid inputs are received. This requirement guards against adverse or unintended system behavior caused by invalid inputs, where information syst...Rule Medium Severity -
Security-relevant software updates to the EDB Postgres Advanced Server must be installed within the time period directed by an authoritative source (e.g., IAVM, CTOs, DTMs, and STIGs).
Security flaws with software applications, including database management systems, are discovered daily. Vendors are constantly updating and patching their products to address newly discovered secur...Rule Medium Severity -
The EDB Postgres Advanced Server must generate audit records when unsuccessful attempts to add privileges/permissions occur.
Failed attempts to change the permissions, privileges, and roles granted to users and roles must be tracked. Without an audit trail, unauthorized attempts to elevate or restrict individuals' and gr...Rule Medium Severity -
The EDB Postgres Advanced Server must generate audit records when privileges/permissions are modified.
Changes in the permissions, privileges, and roles granted to users and roles must be tracked. Without an audit trail, unauthorized elevation or restriction of individuals' and groups' privileges co...Rule Medium Severity -
The EDB Postgres Advanced Server must generate audit records when unsuccessful attempts to modify privileges/permissions occur.
Failed attempts to change the permissions, privileges, and roles granted to users and roles must be tracked. Without an audit trail, unauthorized attempts to elevate or restrict individuals' and gr...Rule Medium Severity -
The EDB Postgres Advanced Server must generate audit records when security objects are modified.
Changes in the database objects (tables, views, procedures, and functions) that record and control permissions, privileges, and roles granted to users and roles must be tracked. Without an audit tr...Rule Medium Severity

The content of the drawer really is up to you. It could have form fields, definition lists, text lists, labels, charts, progress bars, etc. Spacing recommendation is 24px margins. You can put tabs in here, and can also make the drawer scrollable.
