The BIG-IP Core implementation must be configured to protect against or limit the effects of known and unknown types of Denial of Service (DoS) attacks by employing pattern recognition pre-processors when providing content filtering to virtual servers.
An XCCDF Rule
Description
<VulnDiscussion>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. Detection components that use pattern recognition pre-processors 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. 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.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

Remediation - Manual Procedure
If the BIG-IP Core performs content filtering as part of the traffic management functionality, configure the BIG-IP Core as follows:
Configure a policy in the BIG-IP ASM module to protect against or limit the effects of known and unknown types of DoS attacks by employing pattern recognition pre-processors.
Apply ASM policy to the applicable Virtual Server(s) in the BIG-IP LTM module to protect against or limit the effects of known and unknown types of DoS attacks by employing pattern recognition pre-processors when providing content filtering to virtual servers.
