TermTypeDefinitionClassificationsUpdated
data classificationnounMWEThe assignment of a level of sensitivity to data (or information) that results in the specification of controls for each level of classification. Levels of sensitivity of data are assigned according to predefined categories as data are created, amended, enhanced, stored or transmitted. The classification level is an indication of the value or importance of the data to the organization.verified

data lossnounMWEThe exposure of proprietary, sensitive, or classified information through either data theft or data leakage.verified
data loss preventionnounMWEA set of procedures and mechanisms to stop sensitive data from leaving a security boundary.verified
Data loss prevention (DLP) programnounMWEA comprehensive approach (covering people, processes, and systems) of implementing policies and controls designed specifically to discover, monitor, and protect confidential data wherever it is stored, used, or in transit over the network and at the perimeter.verified
data miningnounMWEThe process or techniques used to analyze large sets of existing information to discover previously unrevealed patterns or correlations.verified
Data mirroringnounMWEA back-up process that involves writing the same data to two physical disks or servers simultaneously.verified
Data MultiplexernounMWEa multiplexer that permits two or more data sources to share a common transmission mediumverified
Data Origin AuthenticationnounMWEThe process of verifying that the source of the data is as claimed and that the data has not been modified.verified
