Twelfth Night is a reference to the twelfth night after Christmas Day, called the Eve of the Feast of Epiphany. It was originally a Catholic holiday and therefore, like other Christian feast days, an occasion for revelry.
From Wikipedia, the free encyclopedia. A data breach is the intentional or unintentional release of secure information to an untrusted environment. Other terms for this phenomenon include unintentional information disclosure, data leak and also data spill. Incidents range from concerted attack by black hats with the backing of organized crime or national governments to careless disposal of used computer equipment or data storage media.
The terms data loss and data leak are closely related and are often used interchangeably, though they are somewhat different. Data loss incidents turn into data leak incidents in cases where media containing sensitive information is lost and subsequently acquired by unauthorized party. However, a data leak is possible without the data being lost in the originating side.
