Good Tidings - This post discusses securing the environment of SCADA where in-stations and outstations are located within a sea of insecurity created by the use of the Internet as well as the other 'public' communications channels. These Islands of Security require additions to the SCADA protocol stacks as well as the higher user level metrics and accountability.

Beautiful SCADA Security

I just wanted to say a few words today about the role telecommunications accountability and metrics play in the assurance of security for SCADA Systems. Secure operations of the telecommunications network can be determined by making continuous inferential judgements about the communications traffic between Master Station and its Remote Terminal Units [RTUs] and then being able to 'shut the gate' on any potential operations or connections which are deemed to be insecure.
