We all know that we should secure our computers and smartphones but our printers and MFP’s should also be secured.
If a cybercriminal can access your printer, they can access documents stored on your printer, send jobs to the printer, launch DDoS attacks and perform other malicious activities.
Here are some steps you can take to secure your device.
Change the Password
Change the default administrator username and password. Choose a unique, strong password. Many printers and MFP’s also have a setting that requires you to provide the login credentials when making changes to the device. Enable that feature.
Use a password manager to save your login information. See my post on Using a Password Manager
Update the Firmware
Manufacturers regularly release firmware updates for the devices they produce. These updates address security and performance issues.
Some printers and MFP’s will notify you when there is an update. You can also log into the printer using a web browser or by using the software provided by the manufacturer. Consult the device manual for instructions on how to update the firmware. You can setup a calendar reminder to notify you every few months to check for updates.
Unnecessary Services
Many printers have insecure protocols enabled by default (Telnet, HTTP, FTP, SNMP and AppleTalk) If you are not using these disable them. You can also disable any ports you are not using. Consult your user manual for instructions.
Use a Firewall
A firewall adds an additional layer of protecting that makes it harder for cybercriminals to access your printer remotely from outside of your network. Windows comes with a built in Firewall be sure it is enabled.
If You Don’t Need Network Access Don’t Use It
If you don’t need network access to the printer don’t use it. Connect the printer directly to your computer via USB.
Secure your Network
If you home network is not secure nothing else connected to it is either. Be sure you have enabled all possible security settings on your router. See my post on Secure your Wireless Network
And Is your Old Router a Security Risk
Turn it Off
Unplug or turn off your printer when you are not using it. Hackers cannot gain access to a device that is powered off. I unplug my printer when it is not being used. This not only prevents access, but it also saves on energy costs. Even when a device is powered off it still consumes energy.
