Security 101: Protecting your email from DHAs

Computerworld Philippines staff | Sept. 5, 2013

Rounding out a comprehensive email security arsenal is data leak prevention (DLP) , which prevents valuable data and sensitive personally identifying information from exiting the network via email, either in the body of the message or as an attachment.
