In cryptographic erasure, you’re using a program to reshuffle data on the disk and jumble up the data in a random pattern. You may already know that if you press ‘delete’ on data, it doesn’t remove it from a platter or discharge from logic in HDD and SSD devices respectively. Let’s take a look at non-physical erasure and where you can use it. This is why if you like it or not, you’ll need defined processes that are explicitly documented and signed-off. That’s because your data is only safe in your hands and no others. If you hand this process off to an accredited company, you’ll still need to conduct your storage sanitization prior. You can think of this process as a way to reduce your liability should a claim be made that you took the data and used it nefariously. You’ll have to do this in front of a second party and paperwork produced for each device with a customary sign-off present from the voyeur. Before this, you’ll likely have to work to a company policy that requires either cryptographic erasure or sanitization to occur. You’ll likely implement physical destruction for devices being disposed of. Let’s take a look at each one and some usage cases. These processes are used independently or together, which depends on what exactly is happening to the device. It’s important to use a technique that purges all data from the drive.ģ main types of storage sanitization exist physical destruction, cryptographic erasure, and data erasure.
Devices could be hard drives, flash memory, compact disks, or anything else. Storage or data sanitization is the process of irreversibly destroying data stored on a storage device. īefore we get to the tools you’ll need, let’s take a look at what storage sanitization is! What is Storage Sanitization? This doesn’t mean using hand sanitizer and a cloth, but thoroughly wiping data clean so it can never be recovered. Due to this, it might be good to revisit the kinds of tools and processes you can use for sanitizing a drive. In our own business, we recently had to decommission two business desktop PCs and one personal laptop. If a client finds their data isn’t as safe as they thought, word quickly spreads and a business can quickly become kryptonite. One of the greatest challenges within the IT community now is data-leaks from junked hardware. Having your sensitive business data fall into the wrong hands could spell disaster for your company.
