Group -
Database software, including PostgreSQL configuration files, must be stored in dedicated directories, or DASD pools, separate from the host OS and other applications.
When dealing with change control issues, it should be noted any changes to the hardware, software, and/or firmware components of the information system and/or application can potentially have signi...Rule Medium Severity -
SRG-APP-000133-DB-000200
Group -
Database objects (including but not limited to tables, indexes, storage, stored procedures, functions, triggers, links to software external to the DBMS, etc.) must be owned by database/PostgreSQL principals authorized for ownership.
Within the database, object ownership implies full privileges to the owned object, including the privilege to assign access to the owned objects to other subjects. Database functions and procedures...Rule Medium Severity -
SRG-APP-000133-DB-000362
Group -
The role(s)/group(s) used to modify database structure (including but not necessarily limited to tables, indexes, storage, etc.) and logic modules (stored procedures, functions, triggers, links to software external to PostgreSQL, etc.) must be restricted to authorized users.
If PostgreSQL were to allow any user to make changes to database structure or logic, then those changes might be implemented without undergoing the appropriate testing and approvals that are part o...Rule Medium Severity -
SRG-APP-000141-DB-000091
Group -
Unused database components, PostgreSQL software, and database objects must be removed.

SRG-APP-000142-DB-000094
Group -
PostgreSQL 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 -
SRG-APP-000148-DB-000103
Group -
PostgreSQL must uniquely identify and authenticate organizational users (or processes acting on behalf of organizational users).
To assure accountability and prevent unauthenticated access, organizational users must be identified and authenticated to prevent potential misuse and compromise of the system. Organizational user...Rule Medium Severity -
SRG-APP-000171-DB-000074
Group -
If passwords are used for authentication, PostgreSQL must store only hashed, salted representations of passwords.
The DOD standard for authentication is DOD-approved PKI certificates. Authentication based on User ID and Password may be used only when it is not possible to employ a PKI certificate, and require...Rule High Severity -
SRG-APP-000172-DB-000075
Group -
If passwords are used for authentication, PostgreSQL must transmit only encrypted representations of passwords.
The DOD standard for authentication is DOD-approved PKI certificates. Authentication based on User ID and Password may be used only when it is not possible to employ a PKI certificate, and require...Rule High Severity -
SRG-APP-000175-DB-000067
Group -
PostgreSQL, when using PKI-based authentication, must validate certificates by performing RFC 5280-compliant certification path validation.
The DOD standard for authentication is DOD-approved PKI certificates. A certificate's certification path is the path from the end entity certificate to a trusted root certification authority (CA)....Rule Medium Severity -
SRG-APP-000176-DB-000068
Group -
PostgreSQL must enforce authorized access to all PKI private keys stored/used by PostgreSQL.
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 -
SRG-APP-000177-DB-000069
Group -
PostgreSQL must map the PKI-authenticated identity to an associated user account.
The DOD standard for authentication is DOD-approved PKI certificates. Once a PKI certificate has been validated, it must be mapped to a PostgreSQL user account for the authenticated identity to be ...Rule Medium Severity -
SRG-APP-000179-DB-000114
Group -
PostgreSQL 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 -
SRG-APP-000180-DB-000115
Group -
PostgreSQL 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 -
SRG-APP-000211-DB-000122
Group -
PostgreSQL must separate user functionality (including user interface services) from database management functionality.
Information system management functionality includes functions necessary to administer databases, network components, workstations, or servers and typically requires privileged user access. The se...Rule Medium Severity -
SRG-APP-000220-DB-000149
Group -
PostgreSQL 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 -
SRG-APP-000224-DB-000384
Group -
PostgreSQL must maintain the authenticity of communications sessions by guarding against man-in-the-middle attacks that guess at Session ID values.
One class of man-in-the-middle, or session hijacking, attack involves the adversary guessing at valid session identifiers based on patterns in identifiers already known. The preferred technique fo...Rule Medium Severity -
SRG-APP-000231-DB-000154
Group -
PostgreSQL must protect the confidentiality and integrity of all information at rest.
This control is intended to address the confidentiality and integrity of information at rest in nonmobile devices and covers user information and system information. Information at rest refers to t...Rule High Severity -
SRG-APP-000233-DB-000124
Group -
PostgreSQL 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, an...Rule Medium Severity -

SRG-APP-000251-DB-000160
Group -
PostgreSQL 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 -

Node 2
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.
