Summary

Identity authentication serves as the first line of defence to ensure business security and is one of the most fundamental security services that many other security services depend on. If an identity authentication system is compromised, the effectiveness of other security measures could also be significantly reduced. However, many enterprises, particularly small and medium-sized enterprises, have not yet been able to establish their own comprehensive identity authentication systems with full consideration of security and protection requirements. As a result, they are vulnerable to threats such as credential leakage, malicious login attempts, and password brute-force attacks.

Telecommunication operators have extensive communication network infrastructures and security management technology protection systems. In addition to providing large-scale connectivity services, telecommunication operators also offer a wide range of information services. Furthermore, mobile phone numbers and SIM cards issued by telecommunication operators provide users with convenient and unique identity labels.

Therefore, there is a need for integrated authentication service standards for telecommunication operators to support the development of secure and reliable authentication services, enhance the quality of authentication services, and ensure the security of account systems. Recommendation ITU-T X.1287 specifies a framework for an integrated authentication service provided by telecommunication operators and outlines the security technical requirements for the infrastructure, functions, management systems, and network architecture of the integrated authentication service provided by telecommunication operators. It also provides guidance for the development, deployment, and assessment of secure authentication capabilities within the systems of the integrated authentication service of telecommunication operators.
