Hey @文文 林,

To prevent unauthorized access to your MATLAB Job Scheduler (MJS) cluster, you can implement several security measures:

1. Set Security Levels: Use the "SECURITY_LEVEL" parameter in the "mjs_def" file to set the desired security level. Higher security levels provide better protection.
2. Enable Encrypted Communication: Set "USE_SECURE_COMMUNICATION = true" and "ALL_SERVER_SOCKETS_IN_CLUSTER = true" in the "mjs_def" file to ensure encrypted communication using TLSv1.3.
3. Password Protection: Use password protection for jobs and tasks. Only authorized users with the correct password can access the jobs.
4. LDAP Authentication: Set up LDAP server authentication for user logins to add an extra layer of security.
5. Client Certificates: Use client certificates to verify the identity of users accessing the cluster3

By implementing these measures, you can significantly reduce the risk of unauthorized access to your MJS cluster. For more information regarding the cluster security while using MATLAB Job Scheduler, please refer to the following documentation: https://www.mathworks.com/help/matlab-parallel-server/set-matlab-job-scheduler-cluster-security.html

I hope this helps!
