If the computer is separated from the user, then a magnetic breakaway in the cable causes a USB hotplug removal event to execute a trigger in the app. [28] The trigger executed by the BusKill cable's removal can lock the screen, shutdown, or securely erase the LUKS header and master encryption keys within a few seconds of the cable's separation.

The program, when installed, prompts the user to create a whitelist of devices that are allowed to connect to the computer via its USB ports, which it checks at an adjustable sample rate. The user may also choose what actions the computer will take if it detects a USB device not on the whitelist (by default, it shuts down and erases data from ...
Tails also received funding from the Open Technology Fund, Mozilla, and the Freedom of the Press Foundation. [11] Laura Poitras, Glenn Greenwald, Bruce Schneier and Barton Gellman have each said that Tails was an important tool they used in their work with National Security Agency whistleblower Edward Snowden.

Data erasure can be deployed over a network to target multiple PCs rather than having to erase each one sequentially. In contrast with DOS -based overwriting programs that may not detect all network hardware, Linux -based data erasure software supports high-end server and storage area network (SAN) environments with hardware support for Serial ...
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 Gutmann method, Quick Erase, DoD Short (3 passes), and DOD 5220.22-M (7 passes) are also included as options to handle data remanence. DBAN can be booted from a CD, DVD, USB flash drive or diskless using a Preboot Execution Environment. It is based on Linux and supports PATA (IDE), SCSI and SATA hard drives. DBAN can be configured to ...
On Linux tools like shred and srm can be also used to wipe single files. [13] [14] SSDs are by design more difficult to wipe, since the firmware can write to other cells therefore allowing data recovery. In these instances ATA Secure Erase should be used on the whole drive, with tools like hdparm that support it. [15]
