ISO/IEC 18028-1 provides direction with respect to networks and communications, including on the security aspects of connecting information system networks themselves, and of connecting remote users to networks. It is aimed at those responsible for the management of information security in general, and network security in particular. This direction supports the identification and analysis of the communications related factors that should be taken into account to establish network security requirements, provides an introduction on how to identify appropriate control areas with respect to security associated with connections to communications networks, and provides an overview of the possible control areas including those technical design and implementation topics dealt with in detail in ISO/IEC 18028-2 to ISO/IEC 18028-5.
