EnterpriseDB Postgres Advanced Server (EPAS) Security Technical Implementation Guide
Rules, Groups, and Values defined within the XCCDF Benchmark
-
The EDB Postgres Advanced Server must uniquely identify and authenticate nonorganizational users (or processes acting on behalf of nonorganizational users).
Nonorganizational users include all information system users other than organizational users, which include organizational employees or individuals the organization deems to have equivalent status ...Rule Medium Severity -
The EDB Postgres Advanced Server must invalidate session identifiers upon user logout or other session termination.
Captured sessions can be reused in "replay" attacks. This requirement limits the ability of adversaries to capture and continue to employ previously valid session IDs. This requirement focuses on ...Rule Medium Severity -
The EDB Postgres Advanced Server must isolate security functions from nonsecurity 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 must check the validity of all data inputs except those specifically identified by the organization.
Invalid user input occurs when a user inserts data or characters into an application's data entry fields and the application is unprepared to process that data. This results in unanticipated applic...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 provide nonprivileged users with error messages that provide information necessary for corrective actions without revealing information that could be exploited by adversaries.
Any DBMS or associated application providing too much information in error messages on the screen or printout risks compromising the data and security of the system. The structure and content of er...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 transmission.
Without the association of security labels to information, there is no basis for the DBMS to make security-related access-control decisions. Security labels are abstractions representing the basic...Rule Medium Severity -
Execution of software modules (to include stored procedures, functions, and triggers) with elevated privileges must be restricted to necessary cases only.
In certain situations, to provide required functionality, a DBMS needs to execute internal logic (stored procedures, functions, triggers, etc.) and/or external code modules with elevated privileges...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.
