The Silent Threat: Why Printer Security is the Missing Link in Your Cybersecurity Strategy

Printers, once considered simple and benign office tools, have transformed into sophisticated devices with their own operating systems and network connectivity. According to Quocirca’s Global Print Security Landscape Report 2023, a staggering 61% of IT decision-makers reported data losses due to unsecured printers. 

It's crucial for large corporations, small businesses, and individuals alike to recognize that the everyday devices they rely on can become gateways for cybercriminals. Understanding this risk is the first step towards implementing effective measures to secure these devices and prevent potential breaches. 

By addressing printer security, organizations can close a significant gap in their cybersecurity defenses, ensuring that sensitive information remains protected from prying eyes. Let's dive deeper into why printer security is the missing link in your cybersecurity strategy and how you can strengthen this often-overlooked aspect of your overall protection plan.

Understanding Printer Security Threats 

Printers can be a gateway for various security threats. Unauthorized access to sensitive documents is a significant risk, especially in environments where multiple users share printers. Data breaches can occur if printer data is not encrypted, allowing cybercriminals to intercept and access confidential information. Additionally, compromised printer firmware can be exploited to launch malware attacks, causing widespread damage to an organization's network.

According to HP’s 2023 State of Printer Security report, a survey of 440 organizations revealed that over 50% had experienced an IT security breach, including print security, within the last 12 months. Here are a few common types of printer attacks: 

• Man-in-the-Middle (MITM): Attackers intercept and alter communications between the printer and other devices.
• Firmware Exploitation: Hackers exploit vulnerabilities in the printer's firmware to gain unauthorized access.
  
• Default Password Exploitation: Many printers come with default passwords that are easy to guess, making them vulnerable to attacks.

Thankfully, there are plenty of ways to protect yourself, your company, your employees, and your customers. The bottom line is that organizations can no longer afford to overlook print devices in their overall IT cybersecurity strategy.

Common Misconceptions About Printer Security 

When it comes to cybersecurity, printers are often the overlooked components. Many organizations focus on securing their networks, computers, and mobile devices, but overlook the potential vulnerabilities posed by their printers. 

Let's dive into some of the most common misconceptions about printer security and why they can be dangerous.

Printers are "Dumb" Devices

Many think printers don't need security like computers or servers. However, modern printers are sophisticated and have their own operating systems, making them vulnerable to similar threats. 

Network Security Covers Everything 

Some believe that a secure network means secure printers. In reality, printers need their own security measures, such as updated firmware and strong passwords. 

Physical Security is Enough

Locking a printer in a secure room helps, but it doesn't protect against remote attacks. Networked printers can be accessed from anywhere on the network if not properly secured. 

Default Settings are Safe

Many printers come with default settings that are not secure. It's crucial to change default passwords and configure security settings to protect against unauthorized access. 

Old Printers are Safe

Older printers might not receive firmware updates, leaving them vulnerable to new threats. It's important to update or replace outdated printers to ensure they are secure. 

Print Jobs are Always Secure

People often assume that once a document is sent to the printer, it's safe. However, print jobs can be intercepted or tampered with if the printer or network is compromised.

Integrating Printer Security into a Broader Cybersecurity Strategy

To ensure comprehensive protection, it's essential to integrate printer security into your broader cybersecurity strategy. Here are seven tips to help you enhance your printer security and improve your overall cybersecurity strategy:

1. Policy Development

Establish comprehensive security policies that include printers. This ensures that printers are subject to the same security standards as other network devices.

2. Regular Updates and Patching

Ensure that printer firmware is regularly updated to protect against known vulnerabilities. This is a critical step in maintaining overall network security.

3. User Training

Educate employees about the importance of printer security and best practices, such as not leaving sensitive documents unattended and recognizing potential security threats.

4. Access Controls

Implement role-based access controls to limit who can use the printer and what functions they can access. This reduces the risk of unauthorized use.

5. Network Segmentation

Place printers on a separate network segment to limit the potential damage if they are compromised. This helps contain any security breaches and prevents them from spreading to other parts of the network.

6. Monitoring and Auditing

Regularly monitor printer usage and maintain audit logs to detect and respond to suspicious activities. This helps in identifying potential security breaches early.

7. Encryption

Use encryption for data in transit and at rest to protect sensitive information from being intercepted or accessed by unauthorized users.
