Dark Traffic E-mail Report

Overview

Dark Traffic currently represents up to 70 percent of all inbound e-mail traffic. It is made up of spam, Directory Harvest Attacks (DHA), e-mail Denial of Service (DoS) attacks, malformed SMTP packets, invalid recipient addresses, and other requests and communications unrelated to the delivery of valid e-mail messages. With most solutions available today, it is difficult to identify and block these kinds of e-mail security threats. And the deeper these messages get into an organization’s e-mail network, the greater the cost and higher the security risk. The Dark Traffic Report defines and analyzes e-mail security information gathered through a combination of research interviews with enterprise IT and e-mail administrators, and taps of raw e-mail network data aggregated from traffic monitors positioned in top enterprises throughout the US.
