Scope

This document provides detailed technical control system component requirements
(CRs) associated with the seven foundational requirements (FRs) described in IEC TS
62443-1-1 including defining the requirements for control system capability security
levels and their components, SL-C (component).
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.
NOTE 1.Refer to IEC 62443-2-1 for an equivalent set of non-technical, program-related, capability
requirements necessary for fully achieving a SL-T(control system).
NOTE 2.The trademarks and trade names mentioned in this document are given for the
