Fix Recommendation

Configure the system and system-options to protect against DoS attacks. These are examples of setting that should be adjusted to limit DoS attacks. The exact values will vary based on site traffic.

Use the synflood-limit to configure a TCP SYN packet rate limit.

To configure the limit of TCP/UDP/ICMP packets from a source IP address, use the rate-limit command in configuration mode.

Check Contents

Verify the system and system-options are configured to protect against denial-of-service (DoS) attacks.

(config)# do sh run | in syn
(config)#do show run | in rate-limit

If the system and system-options that limit the effects of common types of DoS attacks are not configured in compliance with the SSP, this is a finding.
