[Snort-sigs] crappy rule for icmp floods

This rule is somewhat crappy but it does detect some of the network
scanning viruses like sasser. Is there a way to use thresholding in a
rule and also have it try to match other rules as well? Or does that go
against snort philosophy...

alert icmp any any -> any any (msg:"20 ICMP in 1 second!!!";threshold:
type both , track by_src, count 20 , seconds 1;)


I am sure there is a better way.
 
Cheers,
Sean
