5G IoT Security – What’s in it for CISOs?

While 5G digital cellular networks are being set up around the world, it will surely take years for widespread coverage. This is the best time to find a way to ease into it while keeping cybersecurity in mind.

A New World of Opportunities, but with Risks

The digital cellular network, 5G opens up a whole new world of opportunities for services that take advantage of the higher speeds and lower latencies that the digital cellular network will offer. But with most significant technology advances there come risks for both network operators and users.

For the network operators, the architecture of the 5G network for tomorrow is going to be complex. While the infrastructure that supports the service ‘slices’ will be virtualized and orchestrated, the Multi-Access Edge Computing required to support new services will open up mobile infrastructure to a broader range of vendors. The intricacy of the control-plane to manage services and end-point connectivity will increase and so will the potential for cybersecurity issues from compromised or poorly behaving devices and applications.

For consumers, privacy would become a big issue. One of the main uses of 5G is massive machine type communications that support the ongoing proliferation of a large number of low power, low-cost IoT devices.so, we can expect a growth in information gathering and exchange.

Organizations will be able to gather a lot of data about online and offline activities. This will allow them to create a more detailed picture of customer behavior. This will allow services tailored to consumer needs, habits, and locations, but it will also enable a new wave of social engineering attacks that would target individuals and the businesses they work within.

However, the major concern is that even if that data is anonymized, it is possible to construct a virtual identity for a user, which can be used to drive analytics and other decision-making systems. This is where regulation needs to be evolved. Users may need protection from pseudo-automated discrimination that can occur without reference to their real-world identity.

5G IoT Security Worries

While massive machine type communication networks are not expected to be deployed widely before 2021, they should eventually become omnipresent. They need to pave the way for wider IoT device usage by public entities, enterprises, industries, and so on. Increased scale for device connectivity and interconnectivity together with “slicing” will enable a new range of IoT services and applications. As most of the existing IoT devices are not developed with cybersecurity as a priority, these devices themselves will be one of the security weak points.

When it is all about consumer-focused IoT, the concerns are evident in any conversation with a network operator who is looking to roll out 5G. Keeping in mind the amount of traffic these 5G connected IoT devices can generate and the potential for the synchronicity of action that can cause resource exhaustion within some aspect of the infrastructure, it is quite clear that these vulnerable devices pose a threat to mobile networks.

Neumetric, a cybersecurity services, consulting & product Organization, can help you reduce your security cost without compromising your security posture. Our years of in-depth experience in handling security for Organizations of all sizes & in multiple industries make it easier for us to quickly execute cost-cutting activities that do not bring value to you, while you continue focusing on the Business objectives of the Organization.

The cybersecurity experts at Neumetric believe that at the most basic level and to protect the device fleet against the vast majority of common attacks and mass-malware outbreaks, Chief Information Security Officers should:

  1. Select manufacturers or vendors who can assure that they provide ongoing support and software updates for the devices.
  2. Use up-to-date software and put up a process in place to assess new vulnerabilities that are disclosed so that they can be managed appropriately.
  3. Have a visibility solution or service in place so that the behavior of devices can be monitored so as to spot and investigate deviations from the norm.
