    摘要： A first risk analysis of a message is performed. In the event the first risk analysis results in a determination that the message meets a first criteria, at least a portion of the message is modified prior to sending a modified version of the message to a specified recipient of the message, and a second risk analysis of the message is performed. The first risk analysis is performed before sending the modified version of the message and the modified version of the message is sent to the specified recipient of the message prior to a conclusion of the second risk analysis. In the event the second risk analysis results in a determination that the message meets a second criteria, content of the message that was previously prevented from being accessed by the specified recipient is provided to the specified recipient of the message.

    摘要： At least one of a measure of trust or a measure of spoofing risk associated with a sender of a message is determined. A measure of similarity between an identifier of the sender of the message and an identifier of at least one trusted contact of a recipient of the message is determined. The measure of similarity is combined with at least one of the measure of trust or the measure of spoofing risk to at least in part determine a combined measure of risk associated with the message. Based at least in part on the combined measure of risk associated with the message, a verification action is performed including by automatically providing an inquiry message that requests a response to be provided.

    摘要： Assessing a risk of a message is disclosed. A sender specified by the message is identified. A measure of authenticity that the sender specified by the message is an actual sender of the message is determined using at least one sender model associated with the sender. The sender model was at least in part automatically generated using one or more previously observed messages. The measure of authenticity is utilized to perform a risk assessment of the message.

    摘要： 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.
