alert tcp $EXTERNAL_NET 0 -> $HOME_NET any (msg:"TCP Source Port of 0";) alert udp $EXTERNAL_NET 0 -> $HOME_NET any (msg:"UDP Source Port of 0";) That was easy. -----Original Message----- From: snort-sigs-admin@lists.sourceforge.net [mailto:snort-sigs-admin@lists.sourceforge.net] On Behalf Of Holger Heimann Sent: Monday, October 04, 2004 12:47 PM To: 'snort-sigs@lists.sourceforge.net' Subject: [Snort-sigs] Signature Proposal 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 -- it.sec GmbH & Co.
