Printers. Every office has one, but do you think any more about it unless it isn’t currently working? Should you?
The answer is yes. Printers can be one of the biggest risks to your network security. Per HP, “There are hundreds of millions of business printers in the world and less than 2% of them are secure”, which is a great thing for anyone wanting to wreak havoc in your organization. Listed below are some of the main threats and vulnerabilities found in printers and some ways to mitigate them.
Unauthorized viewing of important documents is one of the most overlooked things in any organization. People can walk over to a printer and pick up documents that are confidential and see more than they should. If your printer doesn’t allow for secure print, those financials, employee information or other sensitive material are out in the open.
If your printer has the ability securely print, set it up. If it does not, place the printer in a public area where it is highly visible. Securing your print job will cut down on people snooping through documents that aren’t theirs, due to the ability to be caught. If you are printing lots of sensitive material, it might be wise to purchase a printer for yourself and install it in your office, or a management only area, where most employees can’t access.
- Internal Storage
If your printer has an internal storage feature, be sure to wipe it clean before you throw it away or donate it to someone else. Internal storage can save print jobs, scans, faxes and copies created on it. All information should be purged from the machine, just like you would do with a computer.
Always do a thorough wipe of any technology that is being donated or recycled. Cleaning your technology will ensure that your data stays private.
If you have an older model of printer or one that doesn’t have a password-protected feature, it can be very easy for a hacker to access your entire network. If that printer connects to the internet, the ability of hackers to get your business’s information is limitless; transmitting faxes, reroute print jobs elsewhere, retrieve saved copies of documents, or installing malware on your printer to infect your entire network are just some of the examples of problems hackers can cause.
First, always keep your machines updated. Firmware and drivers should be checked regularly to ensure the most updated version is on them. These updates guarantee the latest security features load on your equipment and any holes become fixed.
Second, check your internet connection. If you don’t use this feature, just disable/disconnect it. If you do use it, make sure that you are using an encrypted connection (think https:// instead of just http:// if you access a website from your printer).
HP has a new printer campaign out that shows how easy it is for your printers to get hacked, how they do it, and what information they can gain from it.
