How Can 5G Security Provide Enhanced Services for Network Automation?

Network and cybersecurity can collaborate and work together to provide enhanced services for operators, their customers, and society at large.

FREMONT, CA: It is estimated that 5G possesses the potential to add a staggering $2.2 trillion to the world economy in the coming years. The apps that result in high revenue and customer loyalty in the 5G age will be different from the present scenario. The processors of 5G will have autonomous vehicles, telehealth, smart cities, and logistics. These processors are likely to suffer significant disruption, even loss of life if their security is compromised. Backing up these exciting market opportunities, the operators need to have an entirely new approach to network management, automation, and cybersecurity. The network will be automated end-to-end, and software-controlled processes will be vital to 5G’s infrastructure.

A robust architecture is needed in developing a secure foundation to identify threats and design and deploy adequate security controls. This architecture requires affording operators the flexibility to deliver the services customers require while denying any opportunity to the malicious actors to cause disruption.

The vital elements of a robust 5G security architecture that operators should be aware of are:

SDN Controlled Security- SDN helps in mitigating any breaches by utilizing the intelligence accumulated through northbound APIs to control southbound routers and switches.

Edge Security- Effective edge identification enables enterprises to identify and contain attacks quickly, away from sensitive core networks. Edge computing can cut down on attack detection by placing security monitoring functions closer to users, and developing alternate data transmission routes, making the process more secure.

Hypervisor and Container Security- Virtualized systems are at high threat from a variety of attacks, like data exfiltration and resource starvation. Hypervisor strengthening mechanisms can help guard against bugs and misconfigurations that commonly lead to vulnerability.

Proactive Security Analytics- The operators can identify patterns in data traffic by applying AI and ML to traffic at all points in the network, specifically useful to detect zero-day attacks.

5G is regarded to become one of the biggest technology disruptors, and the security stakes are very high for it. The networks upon which 5G will operate are not building with safety; malicious attackers will soil 5G. These risks should not be ignored.
