As operators expand radio networks with upgrades and new buildouts, open architectures offer clear benefits regarding flexibility and agility. Avoiding vendor lock-in and the ability to build best-of-breed capabilities are very valuable, but many overlook a key benefit that comes along with standardized interfaces and greater visibility – improved security.
Two important factors can drive improved security: improved modularity and reduced interdependencies. With open interfaces available deeper within radio access network (RAN) infrastructure, there are options for isolating controls, greater observability, and independently generated operational telemetry.
Those interfaces provide modularity, which can allow more granular security attestation. It can reduce dependencies on unique software capabilities, making it less risky to update software to apply fixes. Avoiding single vendor lock-in allows operators to put best-of-breed security capabilities to work more easily. These can strengthen operators’ control over their security posture at a time when threats on the network are expanding rapidly. Open architectures offer manifold benefits that are just starting to be realized.
