ISO/IEC 13335-1:2004 Information technology -- Security techniques -- Manage-

ment of information and communications technology se-curity -- Part 1: Concepts and models for information and communications technology security management

ISO/IEC 13335-1:2004 presents the concepts and models fundamental to a basic understanding of ICT security, and addresses the general management issues that are essen-tial to the successful planning, implementation and opera-tion of ICT security.

Part 2 of ISO/IEC 13335 (currently 2nd WD) provides oper-ational guidance on ICT security. Together these parts can be used to help identify and manage all aspects of ICT se-curity.
