Encryption at Rest静态加密
Encryption at rest, when used in conjunction with transport encryption and security policies that protect relevant accounts, passwords, and encryption keys, can help ensure compliance with security and privacy standards, including HIPAA, PCI-DSS, and FERPA.当静态加密与保护相关帐户、密码和加密键的传输加密和安全策略结合使用时，可以帮助确保符合安全和隐私标准，包括HIPAA、PCI-DSS和FERPA。

TLS/SSL (Transport Encryption)（传输加密）
MongoDB supports TLS/SSL (Transport Layer Security/Secure Sockets Layer) to encrypt all of MongoDB's network traffic. TLS/SSL ensures that MongoDB network traffic is only readable by the intended client.MongoDB支持TLS/SSL（传输层安全/安全套接字层）来加密MongoDB的所有网络流量。TLS/SSL确保MongoDB网络流量仅可由预期客户端读取。
