ISO/IEC 27033-4:2014根据安全网关的文件化信息安全政策，给出了使用安全网关（防火墙、应用程序防火墙、入侵保护系统等）保护网络间通信的指南，包括:
1） 识别和分析与安全网关相关的网络安全威胁
2） 基于威胁分析定义安全网关的网络安全要求
3） 使用设计和实施技术解决与典型网络场景相关的威胁和控制问题； 和
4） 解决与实施、操作、监控和审查网络安全网关控制相关的问题。

ISO/IEC 27033-4:2014 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:
1) identifying and analysing network security threats associated with security gateways;
2) defining network security requirements for security gateways based on threat analysis;
3) using techniques for design and implementation to address the threats and control aspects associated with typical network scenarios; and
4) addressing issues associated with implementing, operating, monitoring and reviewing network security gateway controls.
