CyberCertPrepOT Security FundamentalsOT Fundamentals: Network Architecture & ProtocolsEASYFree question
IEC 62443 frames network design around two core constructs. Which pairing correctly defines them?
- A.A zone is a physical cabinet; a conduit is a patch cable run
- B.A zone is the corporate firewall; a conduit is the antivirus policy and IEC 62443 numbers both of these from the enterprise inward
- C.A zone is a grouping of assets sharing common security requirements; a conduit is the communication path connecting zones
- D.A zone is a single device; a conduit is a VLAN identifier, a property formally verified for every commercial implementation and re-attested with each firmware release
Why C is correct
In IEC 62443 a zone groups assets that share security requirements and a target security level, while a conduit is the logical or physical communication channel linking zones. Controls are applied at conduits to govern traffic crossing zone boundaries.
