Beskrivelse

This part of the IEC 62443 series provides detailed technical control system component
requirements (CRs) associated with the seven foundational requirements (FRs) described in
IEC 62443‑1‑1 [1] including defining the requirements for control system capability security
levels, SL-C(component). These requirements would be used by various members of the
industrial automation and control system (IACS) community along with the defined zones and
conduits for the system under consideration (SuC) while developing the appropriate control
system target SL, SL-T(control system), for a specific asset.
As defined in IEC 62443‑1‑1 there are a total of seven 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 requirements are the foundation for control system capability SLs,
SL-C(component). Defining security capability at the control system component level is the
goal and objective of this standard as opposed to SL-T or achieved SLs (SL-A), which are out
of scope.
NOTE – Refer to IEC 62443‑2‑1 [5] for an equivalent set of non-technical, program-related capability SRs
necessary for fully achieving an SL-T(control system).
