Allowing local access to a Unitrends appliance on the local network leaves users open to attacks if an attacker were to gain access to an admin's credentials.
Disabling local network access significantly reduces the attack surface of your Unitrends software.
UniView, VSA, and IT Complete offer highly secure, granular control for access and administration of the Unitrends Recovery Series, Ion, and Max line, without requiring access to the device on the local network.
With the 'manage' feature within UniView a user to disable local access to the Web interface, SSH and Postgres. Once disabled all management would be performed through the Uniview 'manage' feature.
If, for some reason, a device cannot access UniView once enabled a user can re-enable access via physical access to the appliance or virtual console (VMware, Hyper-V for virtual appliances, devices w/ iDrac, or IPMI that support virtual console).
Enabling/Disabling local access:
For increased appliance security, the UniView Portal has a feature that blocks users from logging in directly to the appliance UI. Once local network access has been disabled, users must connect to the appliance from UniView (as described in Connecting to an appliance).
Consider the following before disabling local network access:
- To enable or disable local network access, you must log in to UniView as a Superuser, Admin, or Manage user. (UniView users with Monitor access cannot enable or disable local network access.)
- Hot backup copy to a Unitrends appliance target – To add a self-hosted backup copy target to the appliance, local network access must be enabled on the backup copy target appliance. If needed, use the procedure below to enable local network access on the target appliance before adding the hot backup copy target. Once the target has been added, use the procedure below to disable local network access.
- iSeries protection – To protect your iSeries platform, you must log in to the appliance directly from the local network. Do NOT disable local network access if your appliance is protecting an iSeries environment.
1) First, add the backup appliance to the UniView portal following the steps under Working with appliances in the UniView Backup Portal Guide.
2) Navigate to the 'Status' section in UniView
3) Click on the name of the appliance you want to toggle the local access on to bring up that appliance's details
4) Click the slider to enable/disable local access
5) Once you disable local access, you can manage the appliance by clicking 'Manage'
