While concerns about computer hacking are prevalent, many individuals overlook the potential breach risks associated with their wireless printers. These devices are often used sporadically for specific tasks, such as printing tax forms or mailing labels, and subsequently fade into the background until they are needed again, typically when running out of ink.
However, hackers maintain a keen interest in printers. Unsecured printers serve as a classic method for criminals to exploit and gain access to home networks. In a notable demonstration, Cybernews intentionally targeted printers, successfully breaching nearly 28,000 vulnerable devices worldwide with a 56% success rate. Interestingly, once infiltrated, the compromised printers printed out a guide on printer security. If you’re concerned about the vulnerability of your network through your printer, continue reading for valuable security tips that can enhance your network’s protection and safeguard the data on all your devices.
1. Change the Default Login Credentials
When purchasing a new printer, it often comes with default information provided by the manufacturer for initial setup and connection. This default login information poses a potential security risk. Hackers maintain a master list of these defaults, utilising automated scripts to systematically try each one until they find a successful entry point. To safeguard your printer and network, it is crucial to immediately change this default information during the setup process. Additionally, creating a strong password adds an extra layer of protection against unauthorised access.
2. Keep Printer Firmware Updated
Maintaining the security of your printer goes beyond securing software and applications; it also requires regular firmware updates. Similar to computers, software, and apps, hardware necessitates updates to ensure optimal performance and address security vulnerabilities. Firmware updates, although less conspicuous than software updates, often contain crucial security patches.
3. Use a Network Firewall
Implementing a network firewall plays a crucial role in ensuring the continuous monitoring of network traffic. By effectively blocking suspicious activities, firewalls act as a vital defence mechanism against unauthorised access from hackers
4. Put Your Printer on a Guest Network
In modern home networking, the majority of routers offer the option to establish a guest network. This separate Wi-Fi network operates from the same router used for your main network. Implementing a guest network presents several advantages, primarily in terms of mitigating the risk of hackers traversing between networks and compromising your security.
5. Disable Unused Ports or Services
IoT devices, including printers, typically offer multiple connectivity options. However, it’s important to evaluate whether you truly require all the available ports and services provided by your printer.
These ports can potentially serve as entry points for hackers, making it crucial to disable any unnecessary ports and sharing features. By doing so, you can effectively reduce the risk of a breach and enhance the security of your IoT device.
6. Unplug It When Not in Use
Many individuals may only need to use their printers sporadically, such as once a month or a few times a year. To safeguard against potential security breaches, it is advisable to unplug the printer when it is not in use.
By disconnecting the device, you effectively sever a hacker’s access and eliminate any potential vulnerabilities.
7. Teach Your Family Cybersecurity Best Practices
By following standard best practices for cyber security, not only can everyone’s data be kept more secure, but the risk of identity theft breaches and unauthorised access to devices like baby monitors can also be mitigated.
- Use strong passwords (at least 10-12 characters with a mix of letters, numbers, and symbols).
- Keep software and firmware on devices updated.
- Employ multi-factor authentication whenever possible.
- Enable device firewalls and other protections.
- Install reliable antivirus software on all devices.
- Avoid logging in to accounts through links received via email or text.
- Develop the ability to identify phishing attempts and seeking a second opinion before clicking.
- Schedule regular security checkups with professionals every one to two years.
