Issue/Introduction

Can minion console access be blocked?

Environment

• Carbon Black Response Server: All Versions
• Clustered

Resolution

Yes, minion UI access can be blocked when using a custom WebUI port. The port should be blocked for outside access while leaving communication to master and other minions 

Additional Information

This only works with those using custom WebUI ports separate from the sensor communication port. Blocking outside access to the sensor port will result in sensors being unable to send data
