CASA-FW-000150 - The Cisco ASA must be configured to enable threat detection to mitigate risks of denial-of-service (DoS) attacks.

Information

A firewall experiencing a DoS attack will not be able to handle production traffic load. The high utilization and CPU caused by a DoS attack will also have an effect on control keep-alives and timers used for neighbor peering, resulting in route flapping and will eventually black-hole production traffic.

The device must be configured to contain and limit a DoS attack's effect on the device's resource utilization. The use of redundant components and load balancing are examples of mitigating 'flood-type' DoS attacks through increased capacity.

Solution

Configure threat detection as shown in the example below.

ASA(config)# threat-detection basic-threat
