What is one method to increase security when enabling JMX on Tableau Server?

Enabling JMX (Java Management Extensions) on Tableau Server allows for the monitoring and management of the server, but it also introduces potential security risks if not properly configured. To increase security when JMX is enabled, one effective method is to block off all other hosts from accessing the range of JMX ports. This ensures that only trusted systems can communicate with the JMX server, significantly reducing the attack surface and preventing unauthorized access.

By restricting access to the JMX ports, you maintain tighter control over who can interact with the management interfaces. This proactive approach helps safeguard sensitive configurations and monitoring data from external threats and unauthorized users, making it a crucial step in strengthening the security posture of your Tableau Server environment.

While the other methods mentioned can also contribute to overall security, such as enabling SSL for encrypted communication, requiring strong passwords, or using a private network, blocking access at the network level directly protects against unauthorized attempts to access these management endpoints.
