Transport layer security (TLS) and data encryption at rest

Transport layer security (TLS) is a protocol that provides privacy and data integrity between two communicating applications. Data encryption at rest is the process of encoding and securing data stored in databases, filesystems, or disk storage. In contrast, data in motion is generally protected by networking protocols, such as TLS.

TLS

TLS is a cryptographic protocol that ensures secure communication over a computer network. It is widely used to secure data transmission between a client and a server, protecting it from eavesdropping, tampering, and forgery.

One important use case of TLS is in microservices, where TLS is crucial for securing communication between services over the network. It establishes a secure channel by encrypting data during transmission.

To implement TLS, each microservice can be configured to support HTTPS, the secure version of HTTP. TLS certificates are used to encrypt the communication...
