Linear recommends that customers follow network best practices.
- Install TE units on a segmented network separate from the general corporate network.
- Ensure that the TE network does not have a direct public internet connection.
- Close or block any open ports that are not necessary.
- Remotely connect to TE should be done through a firewall with a secure encrypted tunnel (VPN for example).
What if TE is not functioning as expected?
- The first step is to secure the network. Follow standard network best practices to prevent unauthorized users from regaining access to the device.
- The next step is to recover the device. Contact Linear Technical Services to learn about the TE Recovery Kit
