5G Security Transformation: Why Businesses Need to Prepare Now![]() New 5G networks will offer faster speeds, lower latency and more reliable connections, launching a new era of wireless networking and connected solutions. As a result, it is projected that the number of 5G users will grow to more than a billion by 2023. Many of these customers will take advantage of 5G speeds to deploy new Internet of Things and connected devices that employ edge-based computing to process huge volumes of data. To address this explosive rate of growth and innovation, businesses need to begin supporting the networks, applications, users and cybersecurity demands that will be part of this evolution. Three critical service domains 5G will converge all existing wireless networking services, including mobile devices, WiFi, near field communications and Bluetooth, under a single technological umbrella. Supports of the technology envision three new domains of services:

5G technology will also enable the migration of computing power and storage from remote data centers and cloud installations to the network edge. By provisioning computing services closer to end users, 5G servers will acquire enough intelligence to act as application servers, and 5G service providers will be able to offer additional base station capacity to third parties seeking to deliver new applications and services to end users. These new services will likely include a mix of established mobile computing services (navigation, entertainment, delivery and payment systems), previously non-mobile services (industrial environments, physical access control and office networks), innovative services (such as autonomous vehicles, augmented/virtual reality, cash register-less retail), as well as applications and services we haven't even imagined yet. Security implications of 5G Disrupting traditional relationships between networks, computing resources and end users will also have a tremendous impact on cybersecurity. These include:
Security must support elastic, edge-to-edge hybrid solutions employing proven traditional strategies as well as new approaches. While network segmentation has been positioned as an effective technique for containing cybersecurity risks and protecting sensitive resources, old strategies may not apply in a 5G world. New segmentation strategies will need to navigate local and remote resources that mix segments that you may or may not have the rights to control. Cybersecurity as change enabler The key to addressing the coming security challenges of 5G networks is to be proactive. Fortunately, security professionals have the unique opportunity to build security into their 5G projects right at the beginning. In many cases, this involves applying the security lessons from the current generation of computing and networking solutions. And fortunately, many of the cybersecurity technologies and techniques available today can reduce the potential for harm:
5G offers the promise of tremendously faster connectivity across a vast expansion in connected systems, creating more innovation, productivity and quality-of-life outcomes. To prepare for this opportunity, you need to do three things. First, cybersecurity technologies and best practices need to be seen as enabling strategies rather than as an added cost and complexity tax on innovation. Second, if you prepare now, security worries won't get in the way of your organization's ability to reap the benefits of 5G. And finally, don't wait until you deploy 5G to start thinking about implementing an integrated security fabric framework. Related posts:
