AGA 12 IS A STANDARD TO PROTECT SCADA FROM CYBER ATTACK

AGA 12 is a suite of 4 documents, designated Parts 1 through 4. The four documents
address different aspects of SCADA communication protection.

AGA 12, Part 1 (AGA 12-1) summarizes cyber security policies, the background of the cyber
security problem, and a procedure for testing cryptographic protection systems. This
document educates SCADA operators on the need to do a risk assessment and
recommends an approach for those utilities whose risk assessment reveals a need to
protect their systems with cryptography.

AGA 12-2 is a detailed technical specification for building interoperable cryptographic modules
to protect SCADA communications for low-speed legacy SCADA systems and dial-up
maintenance ports.

AGA 12-3 will describe how to protect high speed communication SCADA systems.

AGA 12-4 will describe how to build next generation SCADA systems so that their cryptography
will be compatible with the legacy systems; this will ease the transition to the newer
designs.

Parts 1 and 2 are close to completion. Parts 3 and 4 are in the planning stage.
