ISC2 Certified Cloud Security Professional (CCSP) Practice Question
During due diligence for a new SaaS contract, a security engineer is asked to recommend language that will reduce the risk of vendor-lock-in if the company later decides to change providers. Which of the following clauses BEST addresses the functional requirement for portability and interoperability?
The provider must submit to annual ISO/IEC 27001 certification audits at its own expense.
The provider reserves the right to change APIs and data models with 60 days' notice.
The provider shall deliver all customer data, schemas, and metadata within 30 days of termination in a documented, industry-standard, machine-readable format via secure transfer.
The provider guarantees 99.9% service availability measured monthly, with service credits for violations.
Portability and interoperability focus on the customer's ability to retrieve applications, data, and associated metadata in a format that can be used on another platform without major re-engineering. Requiring the provider to return all customer information-including schemas and metadata-in an industry-standard, machine-readable format within a defined time frame directly supports this goal and helps prevent vendor lock-in. Audit certifications (ISO/IEC 27001) and availability SLAs are important but unrelated to portability. Allowing the provider to change APIs with limited notice actually increases lock-in risk rather than mitigating it.
