The DataPower Gateway providing user authentication intermediary services using PKI-based user authentication must implement a local cache of revocation data to support path discovery and validation in case of the inability to access revocation information via the network.
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). The intent of this requirement...Rule Medium Severity -

The DataPower Gateway providing user authentication intermediary services using PKI-based user authentication must only accept end entity certificates issued by DoD PKI or DoD-approved PKI Certification Authorities (CAs) for the establishment of protected sessions.
Non-DoD approved PKIs have not 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 assert...Rule Medium Severity -

The DataPower Gateway must implement load balancing to limit the effects of known and unknown types of Denial of Service (DoS) attacks.
If the network does not provide safeguards against DoS attacks, network resources will be unavailable to users. Load balancing provides service redundancy; which service redundancy reduces the susc...Rule Medium Severity -

The DataPower Gateway must behave in a predictable and documented manner that reflects organizational and system objectives when invalid inputs are received.
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 -

The DataPower Gateway providing content filtering must be configured to integrate with a system-wide intrusion detection system.
Without coordinated reporting between separate devices, it is not possible to identify the true scale and possible target of an attack. Integration of the ALG with a system-wide intrusion detectio...Rule Low Severity -

The DataPower Gateway providing content filtering must generate a log record when unauthorized network services are detected.
Unauthorized or unapproved network services lack organizational verification or validation and therefore may be unreliable or serve as malicious rogues for valid services. Examples of network serv...Rule Medium Severity -

The DataPower Gateway providing content filtering must continuously monitor outbound communications traffic crossing internal security boundaries for unusual/unauthorized activities or conditions.
If outbound communications traffic is not continuously monitored, hostile activity may not be detected and prevented. Output from application and traffic monitoring serves as input to continuous mo...Rule Medium Severity -

The DataPower Gateway providing content filtering must send an alert to, at a minimum, the ISSO and ISSM when detection events occur.
Without an alert, security personnel may be unaware of major detection incidents that require immediate action and this delay may result in the loss or compromise of information. Since these incid...Rule Medium Severity -

The DataPower Gateway providing user access control intermediary services must provide the capability for authorized users to capture, record, and log all content related to a selected user session.
Without the capability to capture, record, and log content related to a user session, investigations into suspicious user activity would be hampered. The intent of this requirement is to ensure th...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.
