Private enterprise networks can benefit from Open RAN technology, which goes beyond macro public networks. However, just like Tier 1 operators, private networks need to prioritize security to prevent financial and reputational damage. According to Viavi Marketing Manager Owen O’Donnell, the increasing complexity of networks brings with it more complex cybersecurity challenges.

One of the key concerns with Open RAN networks is the potential increase in vulnerable threat surfaces due to open interfaces. O’Donnell emphasizes that good security practices must be implemented from the design stage to ensure network elements can withstand common threats. While 5G private networks offer improved connectivity, scalability, speed, and security compared to LAN connections and Wi-Fi, they also introduce additional complexities that need to be addressed.

O’Donnell specifically highlights the security implications of the expanded attack surface in Open RAN networks. The introduction of new components from different vendors, such as open radio units, distributed units, central units, and RAN Intelligent Controllers, increases the risk of varying security levels among these components. The interconnected nature of these components also poses a potential risk, as a single vulnerable component could compromise the security of the entire network.

In the context of private networks, the Internet of Things (IoT) plays a crucial role. As digital transformation relies on network-enabled devices, analog devices must be converted to digital for data streaming. However, many industrial IoT devices are optimized for specific tasks and lack software processing capability, making them potential targets for network hacking.

Additionally, the interconnectivity between 3G/4G and 5G networks poses a security challenge. While efforts are being made to enhance the security standards of 5G networks, older generations will still be in use for several years. Threat actors may exploit interconnected interfaces, making attacks more complex and difficult to detect.

In conclusion, Open RAN networks significantly expand the threat surface due to disaggregation, new architecture, elements, interfaces, specifications, vendors, and the use of open source code. Ensuring the security of private networks requires addressing these complexities and implementing robust security measures.
