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.
