Future Networking Technologies: AI, Zero Trust, OT, Wi-Fi 7, and 5G
The Controlware Network Day, held at the end of June 2023 in Garching near Munich, brought together industry experts to discuss the latest trends and challenges in network technology. The event was a platform for open discussions on topics ranging from Zero Trust Networks to the integration of AI and Machine Learning algorithms.
One of the key takeaways from the day was the consensus that Zero Trust Networks are the gold standard for future networks. Bernd Schwefing, Controlware's CEO, predicted that in the future, we will no longer speak of IT and OT, but only of integrated networks. Zero Trust is not a new product, but a new network and security architecture that emphasises the need for all devices in corporate networks to be clearly identifiable and only accessible to a very limited user group.
However, the discussion questioned the appropriateness of the term "Zero Trust Networks". Andreas Helling, a panel participant, raised concerns about who controls the quality of the measures taken by critical companies. Many of Helling's customers, he claimed, still work with Shell scripts, which may not align with the rigorous standards of Zero Trust Networks.
Another hot topic was the integration of AI and Machine Learning algorithms into modern network architectures. While AI technologies can relieve network administrators of routine tasks, as discussed by Christoph Krell from Cisco Germany, they are not yet ready for productive use in network management. ChatGPT was mentioned as an example of AI software that is not yet suitable for network management.
The panel also debated the NIS 2 directive of the EU, which must be implemented by autumn 2024. IT service providers must inform their customers about NIS 2, but the responsibility for implementation remains with the customers. System integrators like Controlware can help customers reduce the effort required to manage their networks by using automation tools. Meraki's cloud-based network management software offers an AI assistant for automating routine tasks.
The Controlware Network Day also shed light on the increasing number of companies with critical infrastructure. Many affected companies are still not aware of NIS 2, which could pose a significant risk. The discussion at the Controlware Network Day questioned the appropriateness of the term "Zero Trust Networks".
The event also touched upon the pros and cons of 5G and Wi-Fi technologies. Wi-Fi is a given in corporate networks, according to the discussion, but the possible replacement of WLAN infrastructure with 5G networks was also discussed. Bernd Schwefing stated that some customers operate as modern antique shops, holding on to outdated networks that are unsuitable for today's requirements.
In conclusion, the Controlware Network Day provided valuable insights into the future of network technology. It was clear that while Zero Trust Networks are the future, not everything can be automated. Taking everyone along is necessary for the acceptance of new technologies, and the time of the IT department as a silo is over. The event underscored the need for IT service providers to act as 'translators' for their customers, helping them understand and adopt new technologies in a way that makes them appealing.
