# Prevention Techniques

- ## How to suppress an attack if you’re the victim:

  - Implement ACL’s at network edges to block ICMP echo responses to your high-visibility hosts, such as IRC servers
    - Again, will impair troubleshooting -- “ping” breaks
    - Will still allow your access pipes to fill
  - Work with upstream providers to determine the help they can provide to you
    - Blocking ICMP echoes for high-visibility hosts from coming through your access pipes
    - Tracing attacks
