Data Leakage/Loss Prevention Systems (DLP)

Sensitive and confidential data are a requisite for most companies, so protection for this data takes great attention by company´s top management, administrators and IT managers. Data leakage causes negative impact on companies. The traditional security approaches, such as firewalls, can´t protect data from leakage. Data leakage/loss prevention (DLP) systems are solutions that protect sensitive data from being in non-trusted hands. This paper is an attempt to survey and study DLP systems that will be conducted as well as a comparison with other security and data protection approaches.
