1. A computer implemented method of wireless communications access security, the method comprising steps that a computer processor of one of a plurality of client devices remote from a server computer distributing a plurality of reference sets of values to the client devices is programmed to perform, the steps comprising:
by the client device, receiving at least one of the distributed reference sets of values from the server computer, each one of the received reference sets pertaining to a respective access point and defining at least one value expected to be extracted from measurement of at least one parameter of a communication channel allocated by the access point for wireless communicating with the client device, and received by the client device, the measurement being made by the client device and during the wireless communication of the client device with the access point;
by the client device, extracting at least one value from the measurement of the at least one parameter of the communication channel as received by the client device, during the wireless communication of the client device with the access point when the access point is active;
by the client device, detecting a deviation of at least one of the at least one extracted value from at least one of the at least one expected value defined by the respective one of the received reference sets of values pertaining to the active access point that the client device is in communication with; and
by the client device and based on the detected deviation, carrying out at least one step of the group consisting of: alerting on a threat indication to a user of the client device, restricting the communication of the client device with the active access point, diverting the communication of the client device with the active access point, and suspending the communication of the client device with the active access point.
