Darik's Boot and Nuke, also known as DBAN / ˈ d iː b æ n /, is a free and open-source project hosted on SourceForge. [2] The program is designed to securely erase a hard disk until its data is permanently removed and no longer recoverable, which is achieved by overwriting the data with pseudorandom numbers generated by Mersenne Twister or ISAAC.

The most common data recovery scenarios involve an operating system failure, malfunction of a storage device, logical failure of storage devices, accidental damage or deletion, etc. (typically, on a single-drive, single-partition, single-OS system), in which case the ultimate goal is simply to copy all important files from the damaged media to another new drive.
The user may choose to keep files, applications or some settings on their Tails drive in "Persistent Storage". Though the Persistent Storage is encrypted by default, it is not hidden and detectable by forensic analysis. [22] While shutting down, Tails overwrites most of the used RAM to avoid a cold boot attack. [23]
Multiboot is environmental technology since it requires only a single storage device to boot multiple files. " Persistence " is the ability, for a Linux Live distribution, to save the changes (to e.g. software, documents, parameters, etc) in the live USB across reboots.
This list is for operating systems distributions that are specifically designed to boot off a (writable) USB flash drive, often called a USB stick. (This does not include operating system distributions with a simplified "installer" designed to boot from a USB drive, but the full OS is intended to be installed on a hard drive). Tin Hat Linux
A common purpose of cold boot attacks is to circumvent software-based disk encryption. Cold boot attacks when used in conjunction with key finding attacks have been demonstrated to be an effective means of circumventing full disk encryption schemes of various vendors and operating systems, even where a Trusted Platform Module (TPM) secure cryptoprocessor is used.
Permanent data erasure goes beyond basic file deletion commands, which only remove direct pointers to the data disk sectors and make the data recovery possible with common software tools. Unlike degaussing and physical destruction, which render the storage media unusable, data erasure removes all information while leaving the disk operable.
