Explanation

By default, Kafka brokers use the PLAINTEXT protocol for network communication. This means: No encryption - data is sent in plain text. No authentication - any client can connect without verifying identity. No authorization - there are no access control checks by default. Security features like TLS, SASL, and ACLs must be explicitly configured.
