ATC-NY and Bigwood Systems, Inc. will design and build Zebra, an innovative access control system for electric power SCADA systems. Access control decisions will depend on the dynamic state of the electric transmission/distribution system, in addition to conventional inputs such as identity. We will develop SCADA Access Control Language (SACL) as a means of establishing the policy to be enforced at each deployment of Zebra. The language will extend classical concepts of access control to encompass our new concept of state-based access control. The primary tasks in Phase I will be to design the details of the access control language, and the architecture.
