SRG-APP-000428-DB-000386
Group -
PostgreSQL must implement cryptographic mechanisms to prevent unauthorized modification of organization-defined information at rest (to include, at a minimum, PII and classified information) on organization-defined information system components.
PostgreSQLs handling data requiring "data at rest" protections must employ cryptographic mechanisms to prevent unauthorized disclosure and modification of the information at rest. These cryptograph...Rule Medium Severity -
SRG-APP-000098-DB-000042
Group -
PostgreSQL must produce audit records containing sufficient information to establish the sources (origins) of the events.
Information system auditing capability is critical for accurate forensic analysis. Without establishing the source of the event, it is impossible to establish, correlate, and investigate the events...Rule Medium Severity -
SRG-APP-000141-DB-000091
Group -
Unused database components, PostgreSQL software, and database objects must be removed.
Information systems are capable of providing a wide variety of functions and services. Some of the functions and services, provided by default, may not be necessary to support essential organizatio...Rule Medium Severity -

SRG-APP-000313-DB-000309
Group -
PostgreSQL must associate organization-defined types of security labels having organization-defined security label values with information in process.
Without the association of security labels to information, there is no basis for PostgreSQL to make security-related access-control decisions. Security labels are abstractions representing the bas...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-000380-DB-000360
Group -
PostgreSQL must enforce access restrictions associated with changes to the configuration of PostgreSQL or database(s).
Failure to provide logical access restrictions associated with changes to configuration may have significant effects on the overall security of the system. When dealing with access restrictions pe...Rule Medium Severity -
SRG-APP-000080-DB-000063
Group -
PostgreSQL must protect against a user falsely repudiating having performed organization-defined actions.
Non-repudiation of actions taken is required in order to maintain data integrity. Examples of particular actions taken by individuals include creating information, sending a message, approving info...Rule Medium Severity -
SRG-APP-000359-DB-000319
Group -
The system must provide a warning to appropriate support staff when allocated audit record storage volume reaches 75% of maximum audit record storage capacity.
Organizations are required to use a central log management system, so, under normal conditions, the audit space allocated to PostgreSQL on its own server will not be an issue. However, space will s...Rule Medium Severity -
SRG-APP-000389-DB-000372
Group -
PostgreSQL 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 -
SRG-APP-000176-DB-000068
Group -
PostgreSQL must enforce authorized access to all PKI private keys stored/utilized 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-000427-DB-000385
Group -
PostgreSQL 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 -
SRG-APP-000095-DB-000039
Group -
PostgreSQL must produce audit records containing sufficient information to establish what type of events occurred.
Information system auditing capability is critical for accurate forensic analysis. Without establishing what type of event occurred, it would be difficult to establish, correlate, and investigate t...Rule Medium Severity -

PostgreSQL must implement cryptographic mechanisms preventing the unauthorized disclosure of organization-defined information at rest on organization-defined information system components.

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-000121-DB-000202
Group -
PostgreSQL must protect its audit features from unauthorized access.
Protecting audit data also includes identifying and protecting the tools used to view and manipulate log data. Depending upon the log format and application, system and application log tools may ...Rule Medium Severity -

SRG-APP-000515-DB-000318
Group -
PostgreSQL must off-load audit data to a separate log management facility; this must be continuous and in near real time for systems with a network connection to the storage facility and weekly or more often for stand-alone systems.
Information stored in one location is vulnerable to accidental or incidental deletion or alteration. Off-loading is a common process in information systems with limited audit storage capacity. P...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-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 use...Rule Medium Severity -
SRG-APP-000295-DB-000305
Group -
PostgreSQL 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 -
SRG-APP-000340-DB-000304
Group -
PostgreSQL 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 ...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.
