TO UNSUBSCRIBE: email "unsubscribe issforum" in the body of your message to [EMAIL PROTECTED] Contact [EMAIL PROTECTED] for help with any problems! ---------------------------------------------------------------------------- Hi, I am currently charged with a challenge: I have to pen-test Siemens Simatic S5 and S7 PLC's. They do OSI over TCP (rfc 1006) for communication, data aquisition, and steering production processes. When I've pentested this, I will have to write rules for ISS realsecure to recognize OSI over TCP conneciton attempts towards PLC's. Anyone ever tried something simular before ? Thx, Patrick
