ISA 95
International standard for enterprise-manufacturing integration frameworks
ISO 27017
International standard for cloud security controls.
Quick Verdict
ISA 95 provides integration models for manufacturing operations, while ISO 27017 offers cloud security controls within ISMS. Manufacturers adopt ISA 95 for ERP-MES harmony; cloud users choose 27017 for shared responsibility and compliance assurance.

ISA 95 Details
What It Is
ANSI/ISA-95/IEC 62264 is a technology-agnostic framework standardizing enterprise-control system integration. It defines models for information exchange between business (Level 4) and manufacturing operations (Level 3), using a hierarchical Purdue model (Levels 0-4) and semantic approaches to reduce integration risks.
Key Components
- Eight parts: models/terminology (Part 1), objects/attributes (Parts 2/4), activities (Part 3), transactions (Part 5), messaging/aliasing/profiles (Parts 6-8).
- Core principles: equipment hierarchies, activity models, consistent object semantics.
- No formal product certification; compliance via architectural alignment and training programs.
Why Organizations Use It
Drives semantic consistency, cuts integration costs/errors, enables IT/OT collaboration. Supports regulatory traceability, OEE improvements, Industry 4.0 scalability. Builds trusted data for analytics, reduces silos in manufacturing transformations.
Implementation Overview
Phased: governance, gap analysis, canonical modeling, pilots, rollouts. Applies to manufacturing firms globally; involves cross-functional teams, data stewardship. Focuses on pilots (3-6 months), full programs 12-36 months.
ISO 27017 Details
What It Is
ISO/IEC 27017:2015 is a code of practice extending ISO/IEC 27002 for information security controls in cloud services. It provides guidance for CSPs and CSCs, focusing on cloud-specific risks like multi-tenancy and shared responsibilities via a risk-based approach within an ISO 27001 ISMS.
Key Components
- Guidance on 37 ISO 27002 controls adapted for cloud.
- 7 additional CLD controls (e.g., segregation, VM hardening, asset removal).
- Built on ISO 27001 ISMS framework.
- Assessed via ISO 27001 audits; no standalone certification.
Why Organizations Use It
- Addresses cloud gaps in generic standards.
- Meets procurement, regulatory (GDPR/CCPA) demands.
- Enhances risk management, trust, and competitive edge.
- Builds stakeholder confidence through auditable controls.
Implementation Overview
- Integrate into existing ISO 27001 via risk assessment and control mapping.
- Key activities: define shared responsibilities, configure virtualization, enable monitoring.
- Applies to all sizes/industries using cloud; global scope.
- Requires certification body audit inclusion (9-12 months for joint).
