防火墙 / 网络分段
管理网络边界、网络分段和流量过滤。
防火墙 / 网络分段由以下 NIST CSF 2.0 成果定义：PR.IR-01 (Networks and environments are protected from unauthorized logical access and usage); ID.AM-03 (Representations of the organization's authorized network communication and internal and external network data flows are maintained)。 对照映射 通过 ISO 27001, CIS v8.1, PCI DSS, CMMC, 800-53 和 NIS2 中已发布的对照表完成映射。 编辑说明 在 SOC 2, DORA 和 Cyber Essentials 中经编辑映射。 在 HIPAA 中仅弱相关。 本站数据中无映射 本站数据中 GDPR, Essential Eight 和 CPS 234 无映射。

关于防火墙 / 网络分段
防火墙和网络分段是基础性的网络安全控制措施，通过限制网络区域之间的流量，缩小入侵事件的影响范围，并阻止横向移动。实施内容包括部署边界防火墙、内部分段防火墙以及微分段，以隔离持卡人数据环境、生产系统和管理网络等敏感环境。防火墙规则应采用默认拒绝原则，至少每半年审查一次，并为每条允许的流量记录业务理由。
