Since its announcement, it must be admitted that 5G is much awaited and is of particular interest to telecommunications operators.
According to a GSMA projection, 20% of global connections will be built through 5G by 2025. This is totally plausible with loan of 57 commercial launches already planned or underway.

Almost all economic sectors are ready to welcome this new network and to make full use of it for its promised benefits. From manufacturing to finance, energy, health and transport, not to mention government services, the positive impact has been much expected. Some behaviours will be expected to change.
However, something undeniable must be raised. When we move to a new technology, it is not uncommon to overlook the security aspect. If for 5G, everyone is focused on the devices, on the coverage is the density of the network as well as on the bandwidth, the question of security remains. And you have to think about it
According to experts, one of the problems, if not the major problem that 5G will cause to businesses, will be cybersecurity in large part. The fact that this new network can involve many players and especially new ones who will want to impose their ecosystem, we should be sure that IT security will not be in good shape.
GsmA, for its part, has focused its analyses on certain key areas regarding the security of the new network. "For operators, the massive increase in network connections and the emergence of new types of applications widen the area of attack and thus the scope of security risks, both for operators and their customers. Within the network, we are seeing a technological shift towards virtualized services that require new security rules. notes the latter in its recent report.
So several questions are legitimately asked in the face of such realities. Which infrastructure will be most targeted? Do we have the skills and the means to protect 5G networks? Are we able to protect ourselves from cyber threats? Is there already a list of threats that could arise or thrive during the expansion of 5G? The example of the Internet of Things, which is supposed to experience a certain revival or even a boom with the announcement of 5G, is palpable. Like what:
– IoT malware, "such as the implantation of botnets on these devices, and the use of CPUs and memory of attacked IoT devices, cause significant response times for applications where time plays an important role, weaken device stability and create an increased risk of restarting these devices. This directly impacts the availability of services that legitimately use these IoT devices. as described by GSMA
– Hacker software rotating on connected objects cause you somehow, rapidly depleting the batteries drop tools in a shorter time than when they were put into service.
These are just examples of cyber threat, which are already known as 4G. We think that with 5G and a massive deployment of connected objects, we should expect a strengthening of security vulnerabilities, an increase in cyber attacks and of course a significant increase in damage. Because all the ingredients will be put together to enable cyber criminals to be very effective.
