Which document is the telecom ISMS implementation guide?

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

Answer: (A)

The question tests knowledge of which ISO/IEC technical report provides telecom-specific guidance for implementing an ISMS. The telecom sector has unique networks, regulatory requirements, and operational risks, so a guide that tailors ISO/IEC 27001 to those realities is necessary. ISO/IEC TR 27015 is designed exactly for this purpose: it offers sector-specific guidance on applying an ISMS in telecom environments, helping organizations align security controls, risk assessment, governance, incident management, and service continuity with telecom practices. The other technical reports address different contexts or generic information security management topics, not the telecom-focused implementation guidance, so they don’t fit as well.
