F5 BIG-IP TMOS Firewall Security Technical Implementation Guide

Rules, Groups, and Values defined within the XCCDF Benchmark

  • The F5 BIG-IP appliance must be configured to use filters that use packet headers and packet attributes, including source and destination IP addresses and ports, to prevent the flow of unauthorized or suspicious traffic between interconnected networks with different security policies, including perimeter firewalls and server VLANs.

    Blocking or restricting detected harmful or suspicious communications between interconnected networks enforces approved authorizations for controlling the flow of traffic. The firewall that filter...

  • In the event that communication with the central audit server is lost, the F5 BIG-IP appliance must continue to queue traffic log records locally.

    It is critical that when the network element is at risk of failing to process traffic logs as required, it takes action to mitigate the failure. Audit processing failures include software/hardware ...

  • The F5 BIG-IP appliance must be configured to use TCP when sending log records to the central audit server.

    If the default UDP protocol is used for communication between the hosts and devices to the central log server, then log records that do not reach the log server are not detected as a data loss. The...

  • The F5 BIG-IP appliance must deny network communications traffic by default and allow network communications traffic by exception (i.e., deny all, permit by exception).

    To prevent malicious or accidental leakage of traffic, organizations must implement a deny-by-default security posture at the network perimeter. Such rulesets prevent many malicious exploits or acc...

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.
