Canadian Standards Association

Preface Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the SCC Mirror Committee (SMC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T). For brevity, this Standard will be referred to as \"CAN/CSA-ISO/IEC 27033-1\" throughout. This Standard supersedes CAN/CSA-ISO/IEC 27033-1:10 (adopted ISO/IEC 27033-1:2009). At the time of publication, ISO/IEC 27033-1:2015 is available from ISO and IEC in English only. CSA Group will publish the French version when it becomes available from ISO and IEC. Scope This part of ISO/IEC 27033 provides an overview of network security and related definitions. It defines and describes the concepts associated with, and provides management guidance on, network security. (Network security applies to the security of devices, security of management activities related to the devices, applications/services, and end-users, in addition to security of the information being transferred across the communication links.) It is relevant to anyone involved in owning, operating or using a network. This includes senior managers and other non-technical managers or users, in addition to managers and administrators who have specific responsibilities for information security and/or network security, network operation, or who are responsible for an organization\'s overall security program and security policy development. It is also relevant to anyone involved in the planning, design and implementation of the architectural aspects of network security. This part of ISO/IEC 27033 also includes the following: provides guidance on how to identify and analyse network security risks and the definition of network security requirements based on that analysis provides an overview of the controls that support network technical security architectures and related technical controls, as well as those non-technical controls and technical controls that are applicable not just to networks introduces how to achieve good quality network technical security architectures, and the risk, design and control aspects associated with typical network scenarios and network \"technology\" areas (which are dealt with in detail in subsequent parts of ISO/IEC 27033), and briefly addresses the issues associated with implementing and operating network security controls, and the on-going monitoring and reviewing of their implementation. Overall, it provides an overview of this International Standard and a \"road map\" to all other parts.
