Data Leak Prvention
DLP (Data Leak Prevention) systems monitor the "exit points" of a company's computing environment for critical, confidential, or sensitive information to prevent it from leaking to the outside world. The exfiltration of this information represents a high risk for the company, and could impact its public image, its competition in the market, and even its income.
Sensitive information can take many forms, such as credit card numbers (PCI), personal information about employees, market strategies and plans, or last year's balance sheet data. It is commonly identified by regular expressions, keyword dictionaries, or file fingerprints (a kind of fingerprint). Many systems combine these methods with OCR modules to recognize text in images.
