Description
DoS is a condition that occurs when a resource is not available for legitimate users. Packet flooding distributed denial-of-service (DDoS) attacks are referred to as volumetric attacks and have the objective of overloading a network or circuit to deny or seriously degrade performance, which denies access to the services that normally traverse the network or circuit. Volumetric attacks have become relatively easy to launch by using readily available tools such as Low Orbit Ion Cannon or by using botnets. Measures to mitigate the effects of a successful volumetric attack must be taken to ensure that sufficient capacity is available for mission-critical traffic. Managing capacity may include, for example, establishing selected network usage priorities or quotas and enforcing them using rate limiting, Quality of Service (QoS), or other resource reservation control methods. These measures may also mitigate the effects of sudden decreases in network capacity that are the result of accidental or intentional physical damage to telecommunications facilities (such as cable cuts or weather-related outages).

Check Text (C-273675r1111323_chk)

Review the switch configuration to verify QoS has been enabled to ensure that sufficient capacity is available for mission-critical traffic. Router# show running-config | include burst ip icmp attack-rate burst-normal 5000 burst-max 10000 lockup 300 ip tcp burst-normal 30 burst-max 100 lockup 300 If the switch is not configured to manage excess bandwidth to limit the effects of packet flooding types of DoS attacks, this is a finding.

Fix Text (F-77671r1110047_fix)

Configure router for DoS: 1. Global config mode: Router# configure terminal 2. Apply configuration parameters: Route (config)#ip icmp attack-rate burst-normal 5000 burst-max 10000 lockup 300 3. Apply configuration parameters: Route (config)#ip tcp burst-normal 30 burst-max 100 lockup 300  4. Save: write memory
