Printer Security Tips to Prevent Cyberattacks Against your Business

This article is written by Webit.

Business leaders invest a lot of time and resources into cybersecurity because they understand that protecting sensitive data is a necessity in the digital age. One business component that often gets overlooked are business printers. They are also vulnerable to cyberattacks, so make sure to follow these tips to ensure your company stays protected.

What makes business printers vulnerable to cyberattacks?

When assessing network security threats, companies primarily focus on servers and computers not only because these are the most exposed to external threats, but also because they get the bulk of cyberattacks. Printers are often at the bottom of the list since they are not prime targets. What’s more, their functions seem to be internal at first glance, as they don’t interact with external systems.

But it’s exactly because of their primary functions, namely printing and scanning, that make print devices perfect cybercriminal targets. Businesses run important documents such as tax forms, employee information, medical records, and financial statements through print devices — information that hackers would definitely love to get their hands on.

And they can, easily.

Network printers store previous print jobs in their hard drive, sometimes including those that have been canceled. If anyone accesses the printer — even remotely — they may be able to see those documents by hacking into the printer using a specialized tool.

Files can also be intercepted during wireless transmission, as modern printers can now be connected to the web. Not only can hackers exploit printers’ open network ports to view data, but they can also take over vulnerable printers and transmit their own data through these machines.

Lastly, hackers can exploit vulnerable printers to bypass your cybersecurity system. Once they find a way in through your printers, crooks can then launch broader cyberattacks from within your network, which can be difficult to contain.

What can you do to protect your business printers?

Business printers should not be disregarded when planning a cybersecurity strategy. Keep your print devices secure by following these best practices:

• Monitor your network surreptitiously and always promptly install printer software updates and patches. Printer manufacturers often release software support or updates, so always be on the lookout for those.
• Change the default password and administrator login credentials of printers with web management capabilities.
• Allow only company-owned devices to connect to your printers.
• Always connect to your printers using secure connections. Conversely, avoid accessing your printers through a public internet connection.
• Restrict printer access by using a firewall.
• If your wireless printer has a feature that requires users to enter a PIN before they can print documents, enable it to prevent unauthorized access.
• If you don’t use your printer for fax and email, isolate your printer from your main company network and disable out-of-network printing.
• If you handle classified data, do not connect your printer to any network. Instead, connect it directly to your computer using data cables or print from a thumb drive.
• Secure your printouts by enabling manual feed. This setting requires a user to manually input paper (or any material to be printed on), reducing the risks of the printed document getting stolen or being left in the printing area.

Another way to secure your printers is by partnering with a resource that can take care of your printer-related worries. From thwarting attacks to reducing management costs to keeping your printer at optimal functionality, IMEC can help.
