1. 1. Disable JMX functionality: You can disable JMX functionality by setting a system property when the application starts, for example by adding the parameter -Dcom.sun.management.jmxremote=false to the startup command.
Enable JMX authentication and authorization: Restrict access to JMX functionality by configuring authentication and authorization. Specify the authentication and authorization configuration file by setting system properties during application startup, such as adding the parameter -Djava.security.auth.login.config=jmx-auth.conf to the startup command.
Configure Firewall: By configuring the firewall, access to the JMX port can be restricted to only allow specific IP addresses or a range of IP addresses to access the JMX port.
Update Java version: Timely updating the Java version can fix the known JMX unauthorized access vulnerability to ensure system security.
Regularly inspect and monitor JMX access logs to promptly identify any abnormal access behavior and take appropriate measures to strengthen security protection.
