How to secure your office printer

Secure your office printer

Office printers are more than just peripheral devices; they are networked gateways that handle sensitive information daily. Whether you’re printing, scanning, or trying to fax for free, these machines process a lot of data. With cyber threats on the rise, securing your office printer is critical for protecting confidential information and ensuring business continuity.

This article explores the risks of unsecured printers, outlines best practices to safeguard your devices, and recommends a secure, high-performance office printer.

The vulnerability of networked printers

Modern office printers connect to corporate networks and often feature wireless, mobile, and cloud printing. While these features boost productivity, they also create potential entry points for cyber attackers. Hackers can exploit these vulnerabilities to gain unauthorized access, intercept sensitive documents, or launch malware attacks through compromised printer firmware.

Potential consequences

Unsecured printers can expose your organization to several risks:

  1. Data breaches: Sensitive information from printed documents can be intercepted.
  2. Ransomware attacks: Compromised printers can become vectors for malware, leading to costly operational disruptions.
  3. Network intrusions: Hackers can use a printer as a stepping stone to infiltrate your broader network.

Best practices to secure your office printer

Below, we’ll explore the best practices to secure your office printer:

Update firmware and software regularly

Regular firmware updates are essential for patching known vulnerabilities. Always download updates from the official manufacturer’s website to ensure authenticity.

  1. Action tip: Set up automatic notifications or scheduled checks for firmware updates.

Implement strong network security

Secure your network to ensure only authorized devices can access the printer:

  1. Use a dedicated VLAN: Isolate the printer on a separate virtual network to limit the impact of a potential breach.
  2. Secure Wi-Fi: Use strong, encrypted Wi-Fi protocols (like WPA3) and complex passwords.
  3. Firewall configurations: Configure your firewall to restrict unnecessary incoming and outgoing traffic to the printer.

Enable printer-specific security features

Many modern printers have built-in security features to protect against cyber threats:

  1. User authentication: Require login credentials to access printer functions.
  2. Secure print release: Hold print jobs until the user authenticates at the device itself.
  3. Encryption: Enable encryption for data transmitted over the network.
  4. Audit trails: Monitor and log printing activities to detect unusual behavior early.

Limit physical access

Physical security is just as important as digital protection:

  1. Access control: Place printers in secure areas with restricted access.
  2. Lockable cabinets: For devices handling highly sensitive documents, consider using locking cabinets.

Educate employees

Human error is often the weakest link in security:

  1. Training Sessions: Conduct regular training on secure printing practices and how to recognize phishing attempts.
  2. Clear Policies: Implement and enforce policies for handling and disposing of printed documents.

Use multi-factor authentication (MFA)

Implement MFA for accessing printer functions, particularly for sensitive operations like viewing confidential scans or releasing secure print jobs.

Conduct regular security audits

Schedule routine security audits to assess vulnerabilities in your printing network. This can include:

  1. Penetration Testing: Engage security experts to test the resilience of your printer’s network.
  2. Log Reviews: Regularly review access logs for suspicious activity.

Integrate with enterprise security solutions

Ensure your printer integrates with your organization’s broader security framework:

  1. Endpoint Security Software: Make sure all devices connected to the printer are protected with up-to-date security software.
  2. Unified Threat Management (UTM): Consider solutions that offer comprehensive monitoring and protection across all network endpoints, including printers.

The future of printer security

As cyber threats evolve, so must your security approach. Future printers are expected to include more sophisticated security measures, like AI-driven anomaly detection and automated threat responses. Investing in secure, modern printing technology is key to protecting your business and maintaining compliance with data protection regulations.
