- About MATRIXX Security
- Introduction to MATRIXX Cloud Native Security
  The information in MATRIXX Security is best-practice information and identifies MATRIXX-specific security considerations and implementations. For container-specific and Kubernetes security information, see the third-party documentation.
- Cloud Native Security
  The information here addresses cloud native security and includes recommendations for securing your cloud native implementation.
- Managing Certificates
  MATRIXX uses certificates signed by a trusted certificate authority, or validated by other means, to establish secure communications with another party with the corresponding private key.

Enable TLS for Event Streaming Framework

Enable Transport Layer Security (TLS) connections for Event Streaming Framework so that it can communicate with a TLS-enabled Kafka cluster.

About this task

These steps assume a non self-signed certificate that accepts a host name alias with a host name that resolves to the IP address of the server running Event Streaming Framework.

Important: Only use certificates obtained from a reputable and trusted certificate authority.

Procedure

In server.properties, add the following TLS configuration:

listeners=SSL://kafka.alias.com:9093 
ssl.keystore.location=path/keystore/keystore.p12
ssl.keystore.password=keystore-password

Start the Zookeeper server.
Start the Kafka server.
In the stream configurations YAML file for Event Streaming Framework, change the bootstrap.servers port to require the Kafka-hosted certificate, and specify that the port is using TLS:
```
settings:
  bootstrap.servers: kafka.mtxssl.com:9093
  security.protocol: SSL
```
