Abstract: A method for detecting resource allocation mismatch among different nodes in a radio access network (RAN) includes: a radio intelligent controller (RIC) polling a centralized unit control plane (CU-CP), a centralized unit user plane (CU-UP), and a distributed unit (DU) to receive information regarding allocated RAN resources associated with a user equipment (UE); and correlating, by the RIC, the received information regarding the allocated RAN resources associated with the UE to determine whether the CU-CP, CU-UP and DU are in sync with respect to the allocated RAN resources associated with the UE. A discrepancy in the allocated RAN resources among the CU-CP, CU-UP and DU indicates stale RAN resource allocation by at least one of the CU-CP, CU-UP and DU.

Abstract: Live and legitimate user traffic is used with in depth knowledge of the business logic for an API specification to perform security testing on a set of APIs. The present system intercepts and analyzes application program interface (API) traffic, identifies user session data, and identifies traffic suitable to duplicate. The identified traffic is duplicated and modified by addition of malicious code. The modified code is then sent to its intended API destination, where it is processed as normal. The resulting response and other traffic as well as the API system and optionally other systems, such as datastore systems, are analyzed to determine if the malicious code resulted in a valid attack. Results from the modified code attack attempts are reported to a user.
