Most digital copiers have hard drives that contain an imagine of every copy the copier makes. As I have previously mentioned in this article, digital copiers may contain sensitive information.
In an effort to make the public aware of this danger, the FTC has released a paper that details the risks.
Some of the highlights of the paper include:
Commercial copiers have come a long way. Today’s generation of networked multifunction devices — known as “digital copiers” — are “smart” machines that are used to copy, print, scan, fax and email documents. Digital copiers require hard disk drives to manage incoming jobs and workloads, and to increase the speed of production.
Copiers often are leased, returned, and then leased again or sold. It’s important to know how to secure data that may be retained on a copier hard drive, and what to do with a hard drive when you return a leased copier or dispose of one you own.
It’s wise to build in data security for each stage of your digital copier’s life-cycle: when you plan to acquire a device, when you buy or lease, while you use it, and when you turn it in or dispose of it.
Their advice if you buy or lease a digital copier:
When you buy or lease a copier:
Evaluate your options for securing the data on the device. Most manufacturers offer data security features with their copiers, either as standard equipment or as optional add-on kits. Typically, these features involve encryption and overwriting.
Encryption is the scrambling of data using a secret code that can be read only by particular software. Digital copiers that offer encryption encode the data stored on the hard drive so that it cannot be retrieved even if the hard drive is removed from the machine.
Overwriting — also known as file wiping or shredding — changes the values of the bits on the disk that make up a file by overwriting existing data with random characters. By overwriting the disk space that the file occupied, its traces are removed, and the file can’t be reconstructed as easily.
When you use the copier:
Take advantage of all its security features. Securely overwrite the entire hard drive at least once a month.
When you finish using the copier:
Check with the manufacturer, dealer, or servicing company for options on securing the hard drive. The company may offer services that will remove the hard drive and return it to you, so you can keep it, dispose of it, or destroy it yourself. Others may overwrite the hard drive for you. Typically, these services involve an additional fee, though you may be able to negotiate for a lower cost if you are leasing or buying a new machine.
One cautionary note about removing a hard drive from a digital copier on your own: hard drives in digital copiers often include required firmware that enables the device to operate. Removing and destroying the hard drive without being able to replace the firmware can render the machine inoperable, which may present problems if you lease the device. Also, hard drives aren’t always easy to find, and some devices may have more than one. Generally, it is advisable to work with skilled technicians rather than to remove the hard drive on your own.
I applaud the FTC for publishing this paper. It is obvious that digital copiers are a real risk to security and could cause security breaches. The more the public is aware of the risk the more they can do to prevent it.
