scope:

This part of ISO/IEC 18028 provides an overview of different techniques of security gateways, of components and of different types of security gateway architectures. It also provides guidelines for selection and configuration of security gateways. Although Personal Firewalls make use of similar techniques, they are outside the scope of this part of ISO/IEC 18028 because they do not serve as security gateways. The intended audiences for this part of ISO/IEC 18028 are technical and managerial personnel, e.g. IT managers, system administrators, network administrators and IT security personnel. It provides guidance in helping the user choose the right type of architecture for a security gateway which best meets their security requirements.
