Claim 8:
9. A system, comprising
at least one processor; and
one or more non-transitory media storing instructions that, when executed by the system, cause the system to perform operations comprising:
performing, at a first time, a first authentication of a first device connecting to a resource;
determining addresses of second devices exchanging data with the first device;
determining first physical locations of the second devices based on the addresses;
determining that at least one of the first physical locations of the second devices is anomalous with respect to second physical locations of third devices that were previously exchanging data with the first device; and
selecting an authentication factor based on determining that at least one of the first physical locations of the second devices is anomalous with respect to the second physical locations of the third devices that were previously exchanging data with the first devices; and
at a second time that is after the first time:
disconnecting the first device from the resource; and
based on disconnecting the first device from the resource, triggering a second authentication of the first device by transmitting, to the first device or to a fourth device, a request for the authentication factor.
