alert udp $EXTERNAL_NET 0 -> $HOME_NET any (msg:"UDP Source Port of 0";)
 
That was easy.

Hi Folks,

 

in addition to the signature 524 and 525 (tcp/udp destination port
zero), we'd like to see similar Signatures with a source port of zero.

 

I've seen that on other IDS and it's been discussed in forensic und
pentest forums also.

 

Thanks a lot,

Holger
