Security in Telecommunications and Information Technology 2012
An overview of issues and the deployment of existing ITU-T Recommendations for secure telecommunications
The purpose of the ITU-T Manual on Security in Telecommunications and Information Technology is to provide a broad introduction to the security work of ITU-T. It is directed towards those who have responsibility for, or an interest in, information and communications security and the related standards, and those who simply need to gain a better understanding of ICT security issues and the corresponding ITU-T Recommendations.

Security architectures
Security architectures, and related models and frameworks, provide a structure and context within which related technical standards can be developed in a consistent manner. In the early 1980s, the need for a framework in which security could be applied in a layered communications architecture was identified. This led to the development of the Recommendation ITU-T X.800. This was the first of a suite of architectural standards to support security services and mechanisms. This work, most of which was done in collaboration with ISO, led to further standards, including security models and frameworks that specify how particular types of protection can be applied in particular environments.
