TISAX Details
What It Is
TISAX (Trusted Information Security Assessment Exchange) is an industry-specific certification framework developed by the ENX Association and VDA for the automotive supply chain. It standardizes assessments of information security, focusing on protecting sensitive data like prototypes, IP, and personal information. Rooted in ISO 27001, it uses a risk-based approach with the VDA ISA catalog for tailored controls across confidentiality, integrity, and availability.
Key Components
- **7 control groupsPolicy, organization, personnel, physical security, access, cryptography, operations.
- 70+ controls in VDA ISA v5.0.4/6.0, plus prototype protection modules.
- 3 assessment levels (AL1-AL3) with maturity scoring (0-5).
- ENX portal for label exchange; 3-year validity.
Why Organizations Use It
OEMs mandate TISAX contractually, preventing revenue loss and market exclusion. It reduces duplicate audits (70-90% savings), mitigates breaches (€4.5M avg cost), builds trust, and enables premium contracts in €2.5T chain.
Implementation Overview
Phased: preparation/gap analysis (1-3m), remediation/tabletops (3-9m), audit (2-4m), sustainment. Scalable for SMEs to globals; ENX-accredited audits required. Targets automotive suppliers, OEMs, service providers globally.
ISO 27017 Details
What It Is
ISO/IEC 27017:2015 is a code of practice extending ISO/IEC 27002 for cloud services. It provides guidance for implementing information security controls in cloud environments, focusing on shared responsibilities between cloud service providers (CSPs) and customers (CSCs). Its risk-based approach integrates with ISO 27001 ISMS, adding cloud-specific adaptations.
Key Components
- Guidance on 37 ISO 27002 controls tailored for cloud.
- 7 additional cloud-specific controls (CLD series) covering shared roles, multi-tenancy segregation, VM hardening, admin operations, monitoring, asset removal, and network alignment.
- Built on ISO 27001 framework; not standalone certification.
- Dual-perspective guidance for CSPs and CSCs.
Why Organizations Use It
- Addresses cloud risks like multi-tenancy and shared responsibility.
- Enhances ISO 27001 compliance for cloud-heavy operations.
- Builds trust with customers and regulators (e.g., GDPR alignment).
- Provides competitive edge in procurement via auditable cloud controls.
Implementation Overview
- Integrate into existing ISO 27001 ISMS via risk assessment and control mapping.
- Key activities: define shared responsibilities, configure segregation/monitoring, update contracts.
- Suited for CSPs, CSCs across sizes/industries; global applicability.
- Audited as part of ISO 27001 certification (joint audits 9-12 months).
