IT executives, CEOs and CIOs should spend some time discussing the definitions given to various security approaches before even thinking about purchases. Some names refer to specific technologies, while others are umbrella terms over a group of point products. Even when there is general agreement on this key question, definitions often subtly vary from vendor to vendor. That lack of precision is one takeaway — perhaps unintended — from a story about Bloor Research's Endpoint Data Protection market update. The writer says endpoint protection is comprised of hard disk encryption, removable storage encryption, internal/external PC port and device connection control, external device control, multi-factor authentication, mobile encryption and control and file-level control.
