The telecom ISMS guide TR 27015 has been published identically as ITU-T X.1051 and which ISO/IEC standard?

• A. ISO/IEC 27011
• B. ISO/IEC 27016
• C. ISO/IEC 27015
• D. ISO/IEC 27019

Answer: (A)

Telecom information security management relies on a sector-specific standard that tailors the general ISMS approach to telecom risks and terminology. ISO/IEC 27011 provides that telecom-focused guidance, building on the core ISMS framework found in ISO/IEC 27001 and 27002. ITU-T X.1051 is the ITU-T counterpart that mirrors the same telecom-oriented content. Because the telecom environment has unique concerns—like network infrastructure, service delivery, and customer data protection—the materials are published identically so organizations in the telecom sector can reference a single, consistent baseline across international standards. That alignment explains why the telecom ISMS guide TR 27015 is published identically as ITU-T X.1051 and ISO/IEC 27011. The other standards are not telecom-specific, so they don’t serve as the matching counterpart for TR 27015.
