ISO/IEC 27011 is specifically tailored for the telecommunications industry and serves as an implementation guide for an Information Security Management System (ISMS) within that context. This standard provides a framework that helps telecom organizations to establish, implement, maintain, and continually improve the security of their information assets. The guidance offered by ISO/IEC 27011 aligns closely with the general principles of ISO/IEC 27001, which focuses on establishing an effective ISMS, but with a clear emphasis on the unique challenges and requirements that telecom companies face.

While ISO/IEC 27001 lays out the overall best practices for an ISMS applicable to any sector, and ISO/IEC 27002 provides a code of practice for information security controls, neither is specific to the telecom industry. ISO/IEC 27005, on the other hand, relates to information security risk management rather than ISMS implementation. Therefore, ISO/IEC 27011 stands out as the most relevant standard for organizations in the telecommunications sector looking to enhance their information security management practices.
