Nebula - How to protect your network devices using Nebula Switches?

Users have reported to us receiving alerts indicating unfamiliar devices attempting to access their network equipment. This includes their Nebula switches. Creating firewall policies have safeguarded their router, however, the Nebula switches still encounter attempted undesired access. This is because network switches are usually located under gateways/routers/firewalls. This makes switches more accessible than most devices. For users who are not familiar with setting a management VLAN, they can use the Nebula switch's ACL to protect their network devices by black-listing devices attempting to access their network equipment.

 

SETUP/STEP BY STEP PROCEDURE:

  • Set static IP addresses for your network equipment. This includes the administrator's PC/laptop/notebooks.
  • Sign in to Nebula CC and go to: 
Site-wide -> Configure -> Switches -> ACL          
  • Set up an ACL to accommodate the traffic you want to block

 

VERIFICATION:

  • Connect a device set with an IP address of the device attempting access.
  • The device should not be able to access the respective ports of network equipment(s).
