8 Tips to Secure Your Printer and Protect Sensitive Information
Printers remain a mainstay in most offices, but they are often overlooked when it comes to cybersecurity. With today’s printers being connected to your devices, network, and the internet, they have become a prime target for cybercriminals. Attackers can exploit printers to gain access to confidential information, control connected computers, and even infiltrate your network.
Luckily, you can secure your printer and prevent potential breaches by following these 8 tips.
Tip #1. Make Sure Your Printers Are Configured Correctly
To avoid security vulnerabilities, start by changing the default password on your printer. Remote access to printers is possible, and simple default passwords like “123456” are easy for hackers to guess.
Also, ensure you’re using your own router for remote printing and never connect to “Guest” networks. This limits potential access points for cybercriminals.
Tip #2. Inspect Print Trays Regularly
It’s a simple but often forgotten tip—check your print trays regularly and remove any unused pages that might contain sensitive information. This helps prevent accidental data leaks.
To further secure your documents, consider investing in a shredder for your office to destroy sensitive papers.
Tip #3. Install Malware and Firmware Updates
Just like your computers, printers need to be protected from malware. Many modern printers come with built-in malware protection, such as HP’s “SureStart” software, which can shut down a printer if it detects an attack.
Regularly updating your printer’s firmware ensures that it stays protected against new threats. Make it a habit to check for updates at least once every quarter.
Tip #4. Limit Access to the Network
Unprotected printers can be an easy entry point for cybercriminals. If your printer doesn’t need constant network access, consider disabling it. If network access is necessary, configure your printer settings to only accept print jobs from trusted devices or networks.
This reduces the risk of external interference and keeps your devices secure.
Tip #5. Update Your Printers
Just as you update your smartphone or computer, you should update your printers as well. Printer manufacturers regularly release updates to address vulnerabilities and enhance security features. Set a reminder to check for printer updates every few months to ensure you’re protected against known security flaws.
Tip #6. Install a Firewall
Many businesses already have firewalls in place for their computers, but it’s also important to secure your printers. Firewalls act as a barrier, blocking unauthorized access attempts.
Make sure your printer is behind a reliable firewall, whether that’s part of your overall network protection or a specialized firewall designed for office equipment.
Tip #7. Encrypt Your Storage
Printers often store data internally, including images of documents printed through them. This can be an easy target for hackers. To secure your data, enable encryption for both your print jobs and the sensitive data stored on your printer’s internal drive.
Many modern printers offer built-in encryption tools. Use them to create secure passwords, remove user IDs for former employees, and ensure documents are deleted from the printer’s queue once they’re printed.
Tip #8. Educate Your Employees
Your employees play a significant role in maintaining the security of your printers. Ensure they are aware of the potential risks and responsibilities that come with using the printer.
Train them to avoid phishing scams, educate them about the dangers of using mobile devices to print, and remind them to always check for sensitive information in print trays. The more they know, the better they can protect your company’s privacy.
By following these tips, you can keep your printer and confidential information safe from cybercriminals, giving you peace of mind that your business remains secure.
