邮件安全
防范通过邮件传播的威胁。
邮件安全由以下 NIST CSF 2.0 成果定义：DE.CM-09 (Computing hardware and software, runtime environments, and their data are monitored to find potentially adverse events); PR.DS-02 (The confidentiality, integrity, and availability of data-in-transit are protected)。 对照映射 通过 ISO 27001, CMMC, 800-53 和 NIS2 中已发布的对照表完成映射。 编辑说明 在 CIS v8.1, SOC 2, PCI DSS 和 Essential Eight 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, DORA, CPS 234 和 Cyber Essentials 无映射。

CIS 9.6: Block unnecessary file types; not in CIS's own crosswalk to CSF 2.0, which covers 49 of 153 safeguards. CIS 9.7: Email server anti-malware; not in CIS's own crosswalk to CSF 2.0, which covers 49 of 153 safeguards. CIS 9.1: Editorial (CIS's published crosswalk covers 49 of 153 safeguards): only fully supported browsers and email clients. CIS 9.4: Editorial (CIS's published crosswalk covers 49 of 153 safeguards): restrict browser and email client extensions. |
| SOC 2 | CC6.8 | Preventing or detecting unauthorized or malicious software | 编辑说明 | CC6.8: AICPA's TSC mappings are not openly licensed; ControlMapping editorial mapping (criterion summaries are ours, not AICPA text). |
| PCI DSS | 5.4.1 | Mechanisms to detect and protect against phishing | 编辑说明 | 5.4.1: Anti-phishing mechanisms; not in NIST's PCI references for these subcategories. |

| 800-53 | SI-3SI-8 | Malicious Code Protection; Spam Protection | 对照映射 | SI-3: via PR.DS-02 SI-8: Spam protection; NIST's CSF 2.0 references don't link SI-8 to these subcategories. |

| GDPR | — | 无要求 | 本站数据中无映射 | 本站数据中没有 GDPR 要求映射到此主题。 |
| NIS2 | 6.9 | Protection against malicious and unauthorised software | 对照映射 | 6.9: via DE.CM-09 |
| Essential Eight | ISM-1488 | Microsoft Office macros in files originating from the internet are blocked | 编辑说明 | ISM-1488: ASD assigns these ISM controls to the Essential Eight; ASD publishes no crosswalk to NIST or ISO, so linking them to topics is ControlMapping editorial. |

关于邮件安全
邮件安全控制用于防御钓鱼攻击、商务邮件欺诈（BEC）、恶意软件投递和垃圾邮件。这些威胁仍是网络入侵最常见的初始攻击途径。实施时包括部署邮件过滤网关；配置SPF、DKIM和DMARC记录以防止域名仿冒；对附件进行沙箱检测；并启用URL重写，以便在点击时检查链接。组织应将技术控制与定期的钓鱼模拟演练相结合，并为员工制定清晰的流程，便于其向安全团队报告可疑邮件。
