F5BI-LT-000215 - The BIG-IP Core implementation must be configured to protect against known and unknown types of Denial of Service (DoS) attacks by employing rate-based attack prevention behavior analysis when providing content filtering to virtual servers.

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.

Detection components that use rate-based behavior analysis can detect attacks when signatures for the attack do not exist or are not installed. These attacks include zero-day attacks, which are new attacks for which vendors have not yet developed signatures. Rate-based behavior analysis can detect sophisticated, Distributed DoS (DDoS) attacks by correlating traffic information from multiple network segments or components.

This requirement applies to the 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.


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 and unknown types of DoS attacks by employing rate-based attack prevention behavior analysis.
