Claim 14:
15. The method of claim 1, wherein the determining of the initial risk is based on scores associated with two or more of the following: trust, reputation, authenticity, and/or risk, wherein:
a score associated with the trust is determined based on a number of messages sent between an apparent sender and a recipient;
a score associated with the reputation is determined based on an extent to which a sender is recognized based on historical traffic;
a score associated with the authenticity is determined based on an analysis of a header of the electronic message, determining whether an originating server is associated with an IP address that has been previously utilized by a sender of the electronic message, whether the electronic message has a valid digital signature, or any combination thereof; and/or
a score associated with the risk is determined based on a heuristically computed score that depends on whether a sender has a Domain-based Message Authentication, Reporting & Conformance (DMARC) reject policy, whether message contents of the electronic message includes a uniform resource locator (URL), whether message contents of the electronic message include a potentially executable attachment, whether message contents of the electronic message include keywords associated with high risk, or any combination thereof.
