1. A non-transitory, computer-readable storage medium comprising instructions recorded thereon that, when executed by at least one data processor of a system of a wireless telecommunications network, cause the system to:
assign a digital signature to a small cell of the wireless telecommunications network,
wherein the digital signature is based on a connectivity schedule indicating a pattern for communicating connection requests, and
wherein the digital signature and the connectivity schedule are unique among multiple small cells of the wireless telecommunications network;
receive a connection request from the small cell,
wherein the connection request includes an instance of a digital signature communicated at a point in time;
detect an anomaly when (i) the instance of the digital signature deviates from the digital signature or (ii) the point in time deviates from an expected time; and
cause performance of an action in response to the detected anomaly.
