Security for industrial automation and control systems - Part 4-2: Technical security requirements for IACS components
As defined in IEC TS 62443-1-1 there are a total of seven foundational requirements (FRs):
a) identification and authentication control (IAC),
b) use control (UC),
c) system integrity (SI),
d) data confidentiality (DC),
e) restricted data flow (RDF),
f) timely response to events (TRE), and
g) resource availability (RA).
These seven FRs are the foundation for defining control system security capability levels. Defining security capability levels for the control system component is the goal and objective of this document as opposed to SL-T or achieved SLs (SL-A), which are out of scope.
