  • The operating system must protect against or limit the effects of Denial of Service (DoS) attacks by ensuring the operating system is implementing rate-limiting measures on impacted network interfaces.

    &lt;VulnDiscussion&gt;DoS is a condition when a resource is not available for legitimate users. When this occurs, the organization either cannot ac...

  • The operating system must implement cryptographic mechanisms to prevent unauthorized disclosure of information and/or detect changes to information during transmission unless otherwise protected by alternative physical safeguards, such as, at a minimum, a Protected Distribution System (PDS).

    &lt;VulnDiscussion&gt;Encrypting information for transmission protects information from unauthorized disclosure and modification. Cryptographic mec...

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.
