Configuring TLS Security for Cloudera Manager Enterprise Edition
Transport Layer Security (TLS) provides encryption and authentication in the communications between the Cloudera Manager Server and Agents. Encryption prevents snooping of communications, and authentication helps prevent malicious Servers or Agents from causing problems in your cluster.
Cloudera Manager supports three levels of TLS security:
- Level 1 (Good): Encrypted communications between the Server and Agents only; no authentication of Server and Agents. See Configuring TLS Encryption for Cloudera Manager below.
- Level 2 (Better): Encrypted communications and authentication of Server to Agents and users; no authentication of Agents to Server. See Configuring TLS Authentication of Server to Agents and Users below.
- Level 3 (Best): Encrypted communications, authentication of Server to Agents, and authentication of Agents to Server. See Configuring TLS Authentication of Agents to Server below.
