ISO 20000 Details
What It Is
ISO/IEC 20000-1:2018 is the certifiable international standard defining requirements for a service management system (SMS). It establishes auditable processes for planning, designing, transitioning, delivering, and improving services across the full lifecycle. Built on Annex SL High-Level Structure (HLS) and PDCA methodology, it emphasizes risk-based thinking and leadership accountability.
Key Components
- Clauses 4-10 cover context, leadership, planning, support, operation, evaluation, improvement.
- Clause 8 details operational domains: service portfolio, relationships, supply/demand, design/transition, resolution, assurance.
- Core processes include incident/problem management, change/release, configuration, availability/continuity, security.
- Certifiable via accredited bodies with Stage 1/2 audits, surveillance, recertification.
Why Organizations Use It
- Drives service reliability, customer trust, risk reduction (e.g., 50% certificate growth).
- Enables market differentiation, procurement wins, integration with ISO 9001/27001.
- Voluntary but supports regulatory compliance, supplier governance, operational efficiency.
Implementation Overview
- Phased: gap analysis, design, deployment, audits (6-18 months typical).
- Applies to all sizes/industries delivering IT/business services.
- Requires tools, training, evidence for certification sustainability.
FedRAMP Details
What It Is
FedRAMP (Federal Risk and Authorization Management Program) is a U.S. government-wide framework standardizing security assessment, authorization, and continuous monitoring for cloud services used by federal agencies. Its primary purpose is enabling "assess once, use many times" to reduce duplication, based on risk-based NIST SP 800-53 controls tailored to FIPS 199 impact levels (Low, Moderate, High).
Key Components
- Baselines with ~150-410 controls across Low/Moderate/High impact levels, plus LI-SaaS.
- Core artifacts: SSP, SAR, POA&M, continuous monitoring plans.
- Built on NIST SP 800-53 Rev 5; involves 3PAOs for independent assessments.
- Compliance via Agency or Program Authorizations, listed on FedRAMP Marketplace.
Why Organizations Use It
- Unlocks federal contracts worth $20M+; required for CMMC-compliant vendors.
- Demonstrates robust security for commercial clients; reduces agency review duplication.
- Enhances risk management, trust, and competitive edge in government procurement.
Implementation Overview
- Multi-phase: sponsor, preparation (SSP drafting), 3PAO assessment, monitoring.
- Targets CSPs; high complexity for federal cloud sales; requires audits and ongoing quarterly reporting.
