The network element must manage excess bandwidth to limit the effects of packet flooding types of Denial of Service (DoS) attacks.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-27396	SRG-NET-000193	SV-34704r1_rule		Medium

Description
A network element 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 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.
