SRG-NET-000015
Group -
The ALG must enforce approved authorizations for logical access to information and system resources by employing identity-based, role-based, and/or attribute-based security policies.
Successful authentication must not automatically give an entity access to an asset or security boundary. The lack of authorization-based access control could result in the immediate compromise and ...Rule Medium Severity -

Group -
The ALG must enforce approved authorizations for controlling the flow of information within the network based on attribute- and content-based inspection of the source, destination, headers, and/or content of the communications traffic.

SRG-NET-000021
Group -
The ALG that is part of a CDS must allow privileged administrators to enable/disable all security policy filters used to enforce information flow control.

Group -
The ALG that is part of a CDS must allow privileged administrators to configure and make changes to all security policy filters that are used to enforce information flow control.

SRG-NET-000033
Group -
The ALG that is part of a CDS must enforce information flow control using organization-defined security policy filters as a basis for flow control decisions for organization-defined information flows.
The use of security policy filters provides protection for the confidentiality of data by restricting the flow of data. Configure organization-defined specific filters and their order of execution...Rule Medium Severity -
SRG-NET-000041
Group -
The ALG providing user access control intermediary services must display the Standard Mandatory DoD-approved Notice and Consent Banner before granting access to the network.
Display of a standardized and approved use notification before granting access to the network ensures privacy and security notification verbiage used is consistent with applicable federal laws, Exe...Rule Medium Severity -
SRG-NET-000042
Group -
The ALG providing user access control intermediary services must retain the Standard Mandatory DoD-approved Notice and Consent Banner on the screen until users acknowledge the usage conditions and take explicit actions to log on for further access.
The banner must be acknowledged by the user prior to allowing the user access to the network. This provides assurance that the user has seen the message and accepted the conditions for access. If t...Rule Medium Severity -
SRG-NET-000043

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.
