Data Security

Data Security - means protecting digital data, such as those in a database, from destructive forces and from the unwanted actions of unauthorized users, such as a cyber attack or a data breach.

Disk Encryption - refers to encryption technology that encrypts data on a hard disk drive. Disk encryption typically takes form in either software or hardware. Disk encryption is often referred to as on-the-fly encryption (OTFE) or transparent encryption.

Backups - are used to ensure data which is lost can be recovered from another source. It is considered essential to keep a backup of any data in most industries and the process is recommended for any files of importance to a user.

Data Masking - of structured data is the process of obscuring (masking) specific data within a database table or cell to ensure that data security is maintained and sensitive information is not exposed to unauthorized personnel. This may include masking the data from users (for example so banking customer representatives can only see the last 4 digits of a customers national identity number), developers (who need real production data to test new software releases but should not be able to see sensitive financial data), outsourcing vendors, etc.

Data Erasure - is a method of software-based overwriting that completely destroys all electronic data residing on a hard drive or other digital media to ensure that no sensitive data is leaked when an asset is retired or reused.
