IEC 62443 Details
What It Is
IEC 62443 is the ISA/IEC series of standards for securing Industrial Automation and Control Systems (IACS). This consensus-based framework addresses OT cybersecurity across governance, risk assessment, system architecture, and product development. Its risk-based approach uses zones/conduits and security levels (SL 0-4) to tailor protections to industrial constraints like availability and safety.
Key Components
- Four groupings: General (-1), Policies (-2), System (-3), Components (-4).
- Seven **Foundational Requirements (FR1-7)IAC, UC, SI, DC, RDF, TRE, RA.
- ~140 component requirements in 4-2; CSMS with maturity levels in 2-1.
- ISASecure certifications: SDLA (4-1), CSA (4-2), SSA (3-3).
Why Organizations Use It
Reduces cyber risks in critical infrastructure; enables supplier qualification and procurement specs. Builds trust via certifications; supports regulatory baselines (horizontal standard). Strategic benefits: safe IIoT, lower insurance, market edge.
Implementation Overview
Phased: CSMS setup (2-1), risk assessment/zoning (3-2), controls (3-3/4-2). For OT sectors globally; multi-year for brownfield sites. Involves audits, certifications for assurance.
FSSC 22000 Details
What It Is
FSSC 22000 (Food Safety System Certification 22000) is a GFSI-benchmarked certification scheme for Food Safety Management Systems (FSMS). It applies across food chain categories like manufacturing, packaging, and logistics. The scheme uses a risk-based approach integrating ISO management principles with HACCP logic.
Key Components
- **Three pillarsISO 22000:2018 (FSMS clauses 4-10), sector-specific PRPs (e.g., ISO/TS 22002 series), FSSC Additional Requirements (e.g., food defense, fraud, allergens).
- Over 100 requirements across governance, operations, and verification.
- Built on PDCA cycle; requires certification audits per ISO 22003-1.
Why Organizations Use It
- Meets retailer mandates and enables global market access.
- Reduces recalls, enhances supply-chain trust via public register.
- Manages risks like adulteration, improves quality and culture.
- Builds competitive edge through GFSI recognition and 40,000+ certifications.
Implementation Overview
- Phased: gap analysis, FSMS design, training, audits.
- Suits all sizes in food sector worldwide.
- Involves CB audits (Stage 1/2), surveillance; 6-12 months typical.
