Data Leakage is the unauthorized movement of information, usually outside an organization. It can be deliberate (data theft) or accidental (data loss).

Data leakage prevention is a top concern for organisations, with scandals frequently dominating the headlines. Many corporate and government organisations have failed to protect their confidential information, including identities of their workforce, their customers and the general public.

Users routinely use and share data without giving sufficient thought to confidentiality and regulatory requirements.

A variety of techniques can e used to prevent data leakage. These include ant-virus software, encryption, firewalls, access control, written policies and improved employee training.
