ISO/IEC 27033-1:2015概述了网络安全和相关定义。它定义和描述了与网络安全相关的概念，并提供了有关网络安全的管理指导。（网络安全适用于设备的安全、与设备、应用程序/服务和最终用户相关的管理活动的安全，以及通过通信链路传输的信息的安全。） 它与任何参与拥有、运营或使用网络的人相关。这包括高级经理和其他非技术经理或用户，以及负责信息安全和/或网络安全、网络运营或负责组织整体安全计划和安全策略制定的经理和管理员。它还与参与网络安全体系结构方面的规划、设计和实施的任何人相关。 ISO/IEC 27033-1:2015还包括以下内容: -就如何识别和分析网络安全风险以及基于该分析的网络安全要求定义提供指导， -概述了支持网络技术安全体系结构和相关技术控制的控制，以及不仅适用于网络的非技术控制和技术控制， -介绍如何实现高质量的网络技术安全体系结构，以及与典型网络场景和网络“技术”领域相关的风险、设计和控制方面（ISO/IEC 27033后续部分将详细介绍），并简要介绍与实施和操作网络安全控制相关的问题，以及对其执行情况的持续监测和审查。 总的来说，它提供了本国际标准的概述和所有其他部分的“路线图”。

ISO/IEC 27033-1:2015 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. ISO/IEC 27033-1:2015 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.
