In this modern world, data security plays a major role and it has been a pressing issue for days. We moved from Floppy Disks to Compact Disks and now to USB drives commonly known as Pen Drives. Data stolen from Pen Drives has been reported on large scale.
People will not take much care for USB drives than the care they took for laptops due to the size and the cost but the data that resides is surely of high cost.
Pen drive lost is common and when the pen drive has been stolen or lost the data in it is also stolen or lost. Many company data has been stolen and lost due to this USB drives.
It is time to know how to secure the data that resides in the computer. For that a tool can be used to encrypt the data in the drive.
User may think there are many tools that are available now on market but the limitation with the tools is that the same software which encrypts the data is required to decrypt the data in the drive.
Linux has a utility named #Cryptsetup. The utility can be used to encrypt the data that resides in the drive. The utility can be downloaded and installed from the software center.
After the installation the drive can be encrypted and the pass phrase or password serves as the key for the encryption and decryption key pair. When the drive has been encrypted with this utility without the pass phrase the data can not be accessed.
The only drawback with this utility is that after encryption the drive can only be opened in Linux operating system and not in any operating system.
P.S : The post is to create awareness and not to be misused.
