What are the security features of Kafka?

Kafka’s security features encompass several aspects:

1. Authentication: Kafka supports multiple authentication mechanisms such as SSL, SASL, OAuth, etc., to verify the identity between clients and servers.
2. Authorization: Kafka can control users’ read and write permissions to topics through ACLs (Access Control Lists), thus ensuring the security of data.
3. Encryption: Kafka supports encrypted data transmission, which can be secured using SSL/TLS to protect data during network communication.
4. Security logs: Kafka is able to log all access logs and control events, allowing administrators to monitor and audit the security of the system.
5. Security plugins: Kafka offers some security plugins, such as Kerberos authentication plugin and LDAP authentication plugin, to help users implement more flexible and secure authentication mechanisms.

Overall, Kafka offers a range of security features that can assist users in establishing a secure and reliable message transmission system.
