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).

Scope:

This part of ISO/IEC 27033 gives guidance for securing communications between networks using security gateways (firewall, application firewall, Intrusion Protection System, etc.) in accordance with a documented information security policy of the security gateways, including:
a) identifying and analysing network security threats associated with security gateways;
b) defining network security requirements for security gateways based on threat analysis;
c) using techniques for design and implementation to address the threats and control aspects associated with typical network scenarios; and
d) addressing issues associated with implementing, operating, monitoring and reviewing network security gateway controls.
