The latest advent of 5G networks could revolutionize the world as it has the potential to advance the digital economy. However, the technology can also create the attack surface for bad actors, since it does not only enable network speed, but supports a diverse set of services and vertical applications such as IoT-enabled apps.
5G networks are able to connect an extensive number of devices and serve various sorts of applications and customers with different security needs. However, the diversity of 5G applications and their scale, amount and latency requirements make it challenging to balance the efficiency, steadiness, and accuracy of security management and policies.
Understanding Security for 5G
5G network is a collection of microprocessors that send troves of data among themselves rapidly. It is significantly more complex than previous generations of networks, which were majorly designed for consumer voice and data services. However, as 5G will support different key functions including advanced mobile broadband, ultra-reliable low-latency communication, and machine to machine communication, it will undergird a host of critical functions.
As more companies and individuals become increasingly reliant on this network, they become more vulnerable to the theft of sensitive data compromising the networks. This fifth generation of network will also expand the number and scale of potential vulnerabilities, upsurge incentives for malicious actors to exploit those vulnerabilities and make it intricate to spot malevolent cyber activities.
Thus, to maintain a secure operation for 5G, network providers will need to a holistic cybersecurity strategy.
Securing 5G Networks
The intricacy of ensuring the security and reliability of 5G networks requires a multi-layered approach comprising technical measures, a legal liability regime, regulatory adjustments, and investments in research and cybersecurity skills training. Compared to all previous generations, 5G is the first mobile architecture aimed at supporting numerous diverse use cases.
SOAR model here can be constructive in securing 5G networks. It aggregates data from various point tools and assesses it for enhanced and cohesive security intelligence within business-defined contexts. This model also contributes to cloud orchestration and automation that are indispensable to the transition from static defense to the adaptive and agile response.
Considering reports, the modern telecommunication networks are generally bifurcated into the radio access network, core network, transport network and interconnect network. Each network encompasses three planes, which are responsible for carrying out a distinct kind of traffic, where each plane can be exposed to unique types of threats.
Digital trust is also supreme in the automated, intelligent and dynamic context of 5G security. It extends to both people and machines that make it an essential foundation for every telecommunications business relationship. So, by embracing and leveraging a holistic cybersecurity approach, SOAR model, and comprehending network types, providers can ensure security for all network activities.
