Claim:
1. A computer-implemented method comprising: initiating, by a first node of a networked computing environment, each of a plurality of different types of man-in-the middle (MITM) detection tests to determine whether communications between first and second nodes of a computing network have been subject to an interception by a third node, wherein each of the different types of MITM detection tests looks for an unexpected response received from a service that would otherwise respond with an expected response; determining, by the first node, that at least one of the tests indicate that the communications have been intercepted by a third node; and providing, by the first node, data characterizing the determination; wherein at least one of the MITM detection tests is a Hypertext Transfer Protocol (HTTP) compression test in which the first node periodically requests that an uncompressed known file be returned compressed and replies are checked to confirm whether the response includes a compressed version of the known file, wherein the compressed version of the known file has an expected integrity and compression state.
