DBMS Data Security

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 Security Technologies::

Full Disk Encryption

Full disk encryption refers to disk encryption technology that encrypts all of the data on the disk or a hard disk drive. Full disk encryption typically takes form in either software (see disk encryption software or hardware (see disk encryption hardware). Full Disk Encryption is often referred to as "FDE," and the combination of hardware and software full disk encryption is often referred to as "end-point full disk encryption," or "end-based full disk encryption.

Strong User Authentication

Single sign-on refers to authentication allowing users to log onto programs, files, folders, and computers once and without being requested to do so again. Single sign-on technology typically is adopted within a "strong user authentication" sense. That is, users are asked to sign-on with multiple factors of authentication. For example:
#password
#smartcard
#fingerprint
#One-time password

International Laws and Standards

  In the UK, the Data Protection Act is used to ensure that personal data is accessible to those whom it concerns, and provides redress to individuals if there are inaccuracies. This is particularly important to ensure individuals are treated fairly, for example for credit checking purposes. The Data Protection Act states that only individuals and companies with legitimate and lawful reasons can process personal information and cannot be shared.


International Standards

The International Standard ISO/IEC 17799 covers data security under the topic of information security, and one of its cardinal principles is that all stored information, i.e. data, should be owned so that it is clear whose responsibility it is to protect and control access to that data.

The Trusted Computing Group is an organization that helps standardize computing security technologies.
