Printers Are Network Access Devices Too
August 10, 2022
Essentially, a modern day printer is another computer device connected to your network. That means it’s a potential access point to your network and should be protected just like a user’s workstation or server. CSO has a post identifying eight tips to secure your network attached printers.
- Limit access privileges to printers
- Disable unused protocols
- Review printer firmware level
- Beware of automatic reports of printer activity
- Know what information your printers process
- Properly manage printer log files
- Confirm security controls
- Review latest guidance for smart card authentication
Management of your printer is typically done through a web browser accessing the device. Basically, the printer is running a website that manages the configuration. If an attacker can gain access to the printer’s “website,” access to network data and other devices is possible. I’m sure there are exceptions, but I have yet to see a printer access that can be protected with MFA. Some don’t even let you change the admin user ID. That means using a complex password is your only defense. I would recommend turning off the internal web access and configuring the printer manually through the control panel. Your copier is nothing more than a really fancy printer, so secure it accordingly.
