How is security ensured on REST and Kafka? What is HTTPS/TLS?

Security in REST and Kafka is ensured by different methods, considering the features of the protocols.

REST:

• Use of HTTPS (HTTP over TLS) for encrypting data during transmission, which protects against interception and MITM attacks.
• Authentication and authorization via tokens (e.g., JWT), API keys, or OAuth.
• Validation and filtering of incoming data to prevent attacks.

Kafka:

• TLS for encrypting traffic between clients and brokers.
• Authentication via SASL (e.g., SCRAM, Kerberos).
• Authorization at the topic and operation level.

HTTPS/TLS: TLS (Transport Layer Security) is a cryptographic protocol that ensures confidentiality and data integrity during transmission over the network. HTTPS is HTTP over TLS, a secure version of HTTP that prevents eavesdropping and data tampering.

Example of HTTPS setup in Go:

http.ListenAndServeTLS(":443", "cert.pem", "key.pem", nil)
