The COMInf network is the infrastructure part of the operation and management system used for guarding the radio access networks developed by Ericsson. This thesis investigates the Ericsson COMInf network; identifies problems covering both functional as well as security aspects of the network and its current monitoring solution, and also presents a set of requirements and recommendations for a future network surveillance solution. As this thesis shows, the COMInf network today has limited functions regarding both network and security supervision. However, implementations of such solutions are possible due to the standardized components used in the network today. To improve the COMInf network, this thesis defines requirements and recommends a network surveillance solution which fulfills these requirements. It is also recommended to update some of the hardware currently in place for the COMInf network.
