Data security is the means of ensuring that data is kept safe from corruption and that access to it is suitably controlled. Thus data security helps to ensure privacy. It also helps in protecting personal data.

|Data loss during storage has two broad causes: hardware and software failure. Head crashes and general wear and tear of media fall into the former category, while software failure typically occurs due to bugs in the code.
|If an uncorrectable data corruption is detected, procedures such as automatic retransmission or restoration from backups can be applied. RAID disk arrays, store and evaluate parity bits for data across a set of hard disks and can reconstruct corrupted data upon of the failure of a single disk.
|It is a growing problem primarily perpetrated by office workers with access to technology such as desktop computers and hand-held devices, since employees often spend a considerable amount of time developing contacts and confidential and copyrighted information for the company they work for they often feel they have some right to the information and are inclined to copy and/or delete part of it when they leave the company, or misuse it while they are still in employment.
