TRENDING Moiz Baig, Security Solutions at Nokia MEA Nokia´s three pillars to augment Telco’s security operation teams by detecting CPU activity spikes or unusual levels of keep-alive signaling. With Machine Learning, the effectiveness to identify communication patterns of viruses and threats would increase continuously. a range of new use cases with a variety of specific requirements. These use cases include support for an enormous density of mobile devices and the need for ultra-low latency communications, they place a high demand on the dependability of the network. Human safety and even human lives depend on the availability and integrity of the network service. “To support each use case in an optimal way, security capabilities will need to be more flexible. For example, security mechanisms used for ultra-low latency, mission-critical applications may not be suitable for massive IoT deployments where mobile devices are inexpensive sensors that have a very limited energy budget and transmit data only occasionally,” Moiz observes. Another driver for 5G security is the changing ecosystem. LTE networks are dominated by large monolithic deployments – each controlled by a single network operator that owns the network infrastructure while also providing all network services. In contrast, 5G networks may be deployed by a number of specialised stakeholders providing end-user 5G network services. According to Moiz, the new 5G architecture itself introduces new types of security threats and an increased attack surface. The potential for dynamic configurations in 5G requires new, dynamic and flexible security architectures. 5G network slices must be appropriately secured for different use cases, and as a result, telcos must focus on measurable security management and assurance. 28 INTELLIGENTCIO “Network security solutions must adapt to this new 5G architecture. To support the dynamic network requirements of 5G for example firewalls must not only be virtualised. They must also be cloud-native continuously orchestrated to meet the performance demands of virtual networks and to support other requirements, such as elastic scaling. A holistic view of the entire mobile transport network and client nodes is necessary so that network operators can apply sufficient security measures, with optimal network placement and design,” he recommends. “Telcos will need to take advantage of multi-dimensional security analytics for rapid detection of threats. A new, dynamic, massively scalable, distributed security paradigm is required to ensure integrity across and through each layer of the network, ensuring that the people, process and tools are aligned with the telco’s security strategy Nokia´s view of customer needs for complete Security lifecycle Modernise to mitigate with security analytics, Machine Learning and automation Moiz advises that telcos need to replace today’s manually-intensive approaches with security management systems built on three pillars – security analytics, Machine Learning and automation – as reflected in Nokia’s NetGuard security solution. Security analytics correlates data from across the network, devices and cloud layers to spot suspicious anomalies and provide insight into the nature of the threat, the associated business risk and recommended response. In an example of a device functioning correctly but leaking data, security analytics could spot trouble and network architecture evolution. Nokia has a wide range of services that can help operators achieve these goals,” Moiz stresses. Telcos are now moving into the 5G era. As telcos around the globe get ready for 5G (more phones, more bandwidth and more b2b use-cases), modern security tools are a must to help protect their networks and their customers, as the traditional security models are simply not enough to deal with the increased threat landscape and challenges 5G will bring to security. n www.intelligentcio.com
