EDB Postgres Advanced Server v11 on Windows Security Technical Implementation Guide
Rules, Groups, and Values defined within the XCCDF Benchmark
-
The EDB Postgres Advanced Server must isolate security functions from non-security functions.
An isolation boundary provides access control and protects the integrity of the hardware, software, and firmware that perform security functions. Security functions are the hardware, software, and...Rule Medium Severity -

The EDB Postgres Advanced Server and associated applications must reserve the use of dynamic code execution for situations that require it.
With respect to database management systems, one class of threat is known as SQL Injection, or more generally, code injection. It takes advantage of the dynamic execution capabilities of various pr...Rule Medium Severity -

The EDB Postgres Advanced Server must automatically terminate a user session after organization-defined conditions or trigger events requiring session disconnect.
This addresses the termination of user-initiated logical sessions in contrast to the termination of network connections that are associated with communications sessions (i.e., network disconnect). ...Rule Medium Severity -

The EDB Postgres Advanced Server must associate organization-defined types of security labels having organization-defined security label values with information in storage.
Without the association of security labels to information, there is no basis for EDB Postgres Advanced Server to make security-related access-control decisions. Security labels are abstractions re...Rule Medium Severity -

EDB Postgres Advanced Server must enforce discretionary access control policies, as defined by the data owner, over defined subjects and objects.
Discretionary Access Control (DAC) is based on the notion that individual users are "owners" of objects and therefore have discretion over who should be authorized to access the object and in which...Rule Medium Severity -

The EDB Postgres Advanced Server must prevent non-privileged users from executing privileged functions, to include disabling, circumventing, or altering implemented security safeguards/countermeasures.
Preventing non-privileged users from executing privileged functions mitigates the risk that unauthorized individuals or processes may gain unnecessary access to information or privileges. System d...Rule Medium Severity -

The EDB Postgres Advanced Server must provide centralized configuration of the content to be captured in audit records generated by all components of the EDB Postgres Advanced Server.
If the configuration of the DBMS's auditing is spread across multiple locations in the database management software, or across multiple commands, only loosely related, it is harder to use and takes...Rule Medium Severity -

The EDB Postgres Advanced Server must allocate audit record storage capacity in accordance with organization-defined audit record storage requirements.
To ensure sufficient storage capacity for the audit logs, the DBMS must be able to allocate audit record storage capacity. Although another requirement (SRG-APP-000515-DB-000318) mandates that audi...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.
