Abstract
An identity profile of a user is tracked using previous message communications of the user. A message identified as potentially from the user is received. The identity profile of the user is identified and obtained. Information is extracted from a header of the received message. A security risk assessment of the received message is determined at least in part by comparing the extracted information with one or more corresponding entries of the identity profile of the user. A security action is performed based on the determined security risk assessment.
