SRG-NET-000313-ALG-000010
Group -
The BIG-IP APM module access policy profile must control remote access methods to virtual servers.
Remote access devices, such as those providing remote access to network devices and information systems, which lack automated control capabilities, increase risk and make remote user access managem...Rule Medium Severity -
SRG-NET-000337-ALG-000096
Group -
The BIG-IP APM module must require users to reauthenticate when the user's role or information authorizations are changed.
Without reauthentication, users may access resources or perform tasks for which authorization has been removed. In addition to the reauthentication requirements associated with session locks, orga...Rule Medium Severity -
SRG-NET-000339-ALG-000090
Group -
The BIG-IP APM module must be configured to require multifactor authentication for remote access with non-privileged accounts to virtual servers in such a way that one of the factors is provided by a device separate from the system gaining access.
For remote access to non-privileged accounts, the purpose of requiring a device that is separate from the information system gaining access for one of the factors during multifactor authentication ...Rule Medium Severity -
SRG-NET-000340-ALG-000091
Group -
The BIG-IP APM module must be configured to require multifactor authentication for remote access with privileged accounts to virtual servers in such a way that one of the factors is provided by a device separate from the system gaining access.
For remote access to privileged accounts, the purpose of requiring a device that is separate from the information system gaining access for one of the factors during multifactor authentication is t...Rule Medium Severity -
SRG-NET-000349-ALG-000106
Group -
The BIG-IP APM module must conform to FICAM-issued profiles.
Without conforming to Federal Identity, Credential, and Access Management (FICAM)-issued profiles, the information system may not be interoperable with FICAM-authentication protocols, such as SAML ...Rule Medium Severity -
SRG-NET-000380-ALG-000128
Group -
The BIG-IP APM module must be configured to handle invalid inputs in a predictable and documented manner that reflects organizational and system objectives.
A common vulnerability of network elements is unpredictable behavior when invalid inputs are received. This requirement guards against adverse or unintended system behavior caused by invalid inputs...Rule Medium Severity -
SRG-NET-000517-ALG-000006
Group -
The BIG-IP APM module access policy profile must be configured to automatically terminate user sessions for users connected to virtual servers when organization-defined conditions or trigger events occur that require a session disconnect.
Automatic session termination addresses the termination of user-initiated logical sessions in contrast to the termination of network connections that are associated with communications sessions (i....Rule Medium Severity -
SRG-NET-000519-ALG-000008
Group -
The BIG-IP APM module access policy profile must be configured to display an explicit logoff message to users, indicating the reliable termination of authenticated communications sessions when disconnecting from virtual servers.
If a user cannot explicitly end a session, the session may remain open and be exploited by an attacker; this is referred to as a zombie session. Users need to be aware of whether or not the session...Rule Medium Severity -
SRG-NET-000337-ALG-000096
Group -
The F5 BIG-IP appliance must be configured to set a "Maximum Session Timeout" value of 8 hours or less.
The Maximum Session Timeout setting configures a limit on the maximum amount of time a user's session is active without needing to reauthenticate. If the value is set to 0 (zero), the user's sessio...Rule Medium Severity -
SRG-NET-000345-ALG-000099
Group -
The F5 BIG-IP appliance must be configured to deny access when revocation data is unavailable using OCSP.
Without configuring a local cache of revocation data, there is the potential to allow access to users who are no longer authorized (users with revoked certificates). Caching of CRL files on BIG-IP...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.
