Group -
The CA API 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 -

SRG-NET-000362-ALG-000112
Group -
The CA API Gateway providing content filtering must protect against known and unknown types of Denial of Service (DoS) attacks by employing rate-based attack prevention behavior analysis.

SRG-NET-000392-ALG-000141
Group -
The CA API 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 inci...Rule Medium Severity -

Group -
The CA API Gateway providing content filtering must generate a notification on the console when root-level intrusion events that attempt to provide unauthorized privileged access are detected.

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.
