  • A BIND 9.x server implementation must manage excess capacity, bandwidth, or other redundancy to limit the effects of information flooding types of Denial of Service (DoS) attacks.

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

  • On the BIND 9.x server the platform on which the name server software is hosted must be configured to send outgoing DNS messages from a random port.

    &lt;VulnDiscussion&gt;Hosts that run the name server software should not provide any other services and therefore should be configured to respond t...

  • A BIND 9.x caching name server must implement DNSSEC validation to check all DNS queries for invalid input.

    &lt;VulnDiscussion&gt;A common vulnerability of applications is unpredictable behavior when invalid inputs are received. This requirement guards ag...

  • A BIND 9.x master name server must limit the number of concurrent zone transfers between authorized secondary name servers.

    &lt;VulnDiscussion&gt;Limiting the number of concurrent sessions reduces the risk of Denial of Service (DoS) to the DNS implementation. Name serve...

  • The BIND 9.x server implementation must uniquely identify and authenticate the other DNS server before responding to a server-to-server transaction, zone transfer and/or dynamic update request using cryptographically based bidirectional authentication to protect the integrity of the information in transit.

    &lt;VulnDiscussion&gt;Server-to-server (zone transfer) transactions are provided by TSIG, which enforces mutual server authentication using a key t...

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.
