Email Security Threats: Not Just From the Outside

Security and risk (S&R) pros have the challenging task of using finite resources (including budget, time, and people) to protect their businesses from every possible attack type. On top of this, S&R pros don't just need to watch out for threats coming from outside their walls, but must keep an eye on internal threats as well. S&R decision-makers face threats from three groups of insiders – compromised accounts (internal accounts that have been compromised by external attacks), careless misuse (internal policy violators and those who accidentally leak or expose data or systems), and malicious insiders (insiders who purposefully take or misuse data or exploit systems), and they must be prepared for each. In February 2017, Mimecast commissioned Forrester Consulting to evaluate the state of enterprise security readiness for internal email threats.
