Software, applications, and configuration files that are part of, or related to, the EDB Postgres Advanced Server installation must be monitored to discover unauthorized changes.
If the system were to allow any user to make changes to software libraries, then those changes might be implemented without undergoing the appropriate testing and approvals that are part of a robus...Rule Medium Severity -

The EDB Postgres Advanced Server must be configured to prohibit or restrict the use of organization-defined functions, ports, protocols, and/or services, as defined in the PPSM CAL and vulnerability assessments.
In order to prevent unauthorized connection of devices, unauthorized transfer of information, or unauthorized tunneling (i.e., embedding of data types within data types), organizations must disable...Rule Medium Severity -

If DBMS authentication, using passwords, is employed, EDB Postgres Advanced Server must enforce the DOD standards for password complexity and lifetime.
OS/enterprise authentication and identification must be used (SRG-APP-000023-DB-000001). Native DBMS authentication may be used only when circumstances make it unavoidable, and must be documented a...Rule High Severity -

The EDB Postgres Advanced Server must enforce authorized access to all PKI private keys stored/used by the EDB Postgres Advanced Server.
The DOD standard for authentication is DOD-approved PKI certificates. PKI certificate-based authentication is performed by requiring the certificate holder to cryptographically prove possession of ...Rule High Severity -

The EDB Postgres Advanced Server must record time stamps in audit records and application data that can be mapped to Coordinated Universal Time (UTC, formerly GMT).
If time stamps are not consistently applied and there is no common time reference, it is difficult to perform forensic analysis. Time stamps generated by the DBMS must include date and time. Time ...Rule Medium Severity -

Applications must obscure feedback of authentication information during the authentication process to protect the information from possible exploitation/use by unauthorized individuals.
To prevent the compromise of authentication information, such as passwords and PINs, during the authentication process, the feedback from the information system must not provide any information tha...Rule High Severity -

The EDB Postgres Advanced Server must use NIST FIPS 140-2 or 140-3 validated cryptographic modules for cryptographic operations.
Use of weak or not validated cryptographic algorithms undermines the purposes of using encryption and digital signatures to protect data. Weak algorithms can be easily broken and not validated cryp...Rule High Severity -

The EDB Postgres Advanced Server must be configured on a platform that has a NIST-certified FIPS 140-2 or 140-3 installation of OpenSSL.
PostgreSQL uses OpenSSL for the underlying encryption layer. It must be installed on an operating system that contains a certified FIPS 140-2 or 140-3 distribution of OpenSSL. For other operating s...Rule High 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.
