Control System Security
Prevention of intentional or unintentional interference with the proper operation of industrial automation and control system through the use of computers,networks,operating systems,applications and other programmable configurable components of the system.
Some examples- SCADA security Industrial automation and control system security Control system cyber security Industrial network security Electronic security for industrial automation and control systems
Why control System security is important?
These systems control the services that we consider essential for our way of life.electricity,petroleum production,water,transportation and communication
Recent events have demonstrated the vulnerability of these systems to cyber incidents.
The US and other government have passed regulation protection for control systems operating critical infrastructure.
Standards for industrial Cyber security
ISA - www.isa.org -ISA99 industrial automation and control systems security. -ISA security compliance institute (ISCI)
IEC - www.iec.ch IEC 62443 series of standards equivalent to ISA
WIB- www.WIB.nl -Plant security working group
ISA99 working group 7(WG 7)
Safety and security of industrial automation and control systems
Joint effort with ISA84 and other industry group
Initial Tasks - 1.Completing a security assurance level methodology for cyber security,similar to that of the current safety integrity level (SIL) defined in ISA84 2.Defining and developing processes for identifying intentional and systematic threats that can expose process hazards.
