Here are six tips to keep your network and imaging devices secure:

  1. Digital certificates — Certificate authority (CA) certificates allow a device to trust and validate the credentials of another system on the network.
  2. Port Filtering — Filtering increases control over network device activity and is used to configure devices and filter out traffic on specific network ports.
  3. IP address Filtering — Network devices are configured to allow TCP/IP connections only from a specific list of TCP/IP addresses.
  4. Role based access control — Individual users and groups use network name and password credentials to access devices, and the device determines if a user has appropriate access.
  5. Contact and contactless card authentication – Imaging devices should support a number of contact and contactless card solutions for basic badge authentication when a user’s identity is linked to an ID badge.
  6. Firmware updates — Firmware updates should be transmitted over the network so devices can be updated together and simultaneously.
