The confusion related to “DLP” is fueled by the fact there are two definitions of the same acronym, Data Leakage Prevention and Data Loss Protection, which are often interchanged as Data Leakage Protection and Data Loss Prevention. Whatever definition you use, the purpose of DLP is to restrain data outflow in four ways:
1. Web Control: Prevent users from visiting sites purporting guns, drugs, etc.
2. Application Control: Avoid accessing some applications like CRM, file share, dropbox.
3. Peripheral Control: Manage external connections typically via USB ports like to a printer or external hard drive.
4. Content Control: Monitor documents and email to flag or block content with sensitive data like wire transfer detail or SS number.
