Disk encryption is a technology that encrypts the data stored on a hard drive. Data on an encrypted hard drive cannot be read by anyone who does not have access to the appropriate key or password. This can help prevent access to data by unauthorized persons and provides a layer of security against hackers and other online threats.
There are multiple approaches available. They are divided into three main categories: software-based, hardware-based within the storage device, and hardware-based elsewhere. Hardware-based full disk encryption within the storage device are called self-encrypting drives and have no impact on performance whatsoever. Furthermore, the media-encryption key never leaves the device itself and is therefore not available to any virus in the operating system.
Device encryption is available in Pro versions of Windows operating systems. Another popular choice is BitLocker. At Orillia ProNet, Inc we help provide the best single or multiple solution for protecting data.
