F5BI-LT-000219 - The BIG-IP Core implementation must be configured to protect against known types of Denial of Service (DoS) attacks by employing signatures when providing content filtering to virtual servers.

Information

If the network does not provide safeguards against DoS attacks, network resources will be unavailable to users.

Installation of content filtering gateways and application layer firewalls at key boundaries in the architecture mitigates the risk of DoS attacks. These attacks can be detected by matching observed communications traffic with patterns of known attacks and monitoring for anomalies in traffic volume, type, or protocol usage.

Detection components that use signatures can detect known attacks by using known attack signatures. Signatures are usually obtained from and updated by the ALG component vendor.

This requirement applies to the communications traffic functionality of the ALG as it pertains to handling communications traffic rather than to the ALG device itself.

NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.

Solution

If the BIG-IP Core performs content filtering as part of the traffic management functionality, configure the BIG-IP Core to protect against or limit the effects of known types of DoS attacks by employing signatures.
