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 ...

Encryption with key erasure involves encrypting all sensitive material in a way that requires a secure key to decrypt the information when it needs to be used. [14] When the information needs to be deleted, the secure key can be erased. This provides a greater ease of use, and a speedier data wipe, than other software methods because it ...
Changing the encryption key renders inaccessible all data stored on a SED, which is an easy and very fast method for achieving a 100% data erasure. Theft of an SED results in a physical asset loss, but the stored data is inaccessible without the decryption key that is not stored on a SED, assuming there are no effective attacks against AES or ...
In order not to fill the data store with useless information, there is a policy to remove tombstones completely. For this, the system checks the age of the tombstone and removes it after a prescribed time has elapsed. In Apache Cassandra, this elapsed time is set with the GCGraceSeconds parameter [1] and the process is named Compaction. [2]
In computer programming, create, read, update, and delete (CRUD) are the four basic operations (actions) of persistent storage. [1] CRUD is also sometimes used to describe user interface conventions that facilitate viewing, searching, and changing information using computer-based forms and reports .
Data remanence is the residual representation of digital data that remains even after attempts have been made to remove or erase the data. This residue may result from data being left intact by a nominal file deletion operation, by reformatting of storage media that does not remove data previously written to the media, or through physical properties of the storage media that allow previously ...
In Windows 7 and later, significant hardware changes (e.g. motherboard) may require a re-activation. In Windows 10 and 11, a user can run the Activation Troubleshooter if the user has changed hardware on their device recently. If the hardware has changed again after activation, they must wait 30 days before running the troubleshooter again.
