A massive number of connected devices are supported by 5G networks that enable an increase in bandwidth and create a threat landscape, unlike other systems. The industry requires maintaining a laser-like focus on 5G security to bring healthy and robust communication in the future.
FREMONT, CA: 5G might be overhyped, but it is indeed the factor that suggests the beginning of the next-gen network. It represents the most significant advancement in the history of mobile communications and networks. The evolution of 3G and 4G delivered vital performance improvements and brought in new abilities that helped mobile technology to develop into an integral part of daily life.
5G offers gigabit speeds and higher capacities that can bring faster and reliable connections. Mobile operators, after the shift to 5G, are reconstructing their networks to significantly reduce the time taken by the data to go across the network. Sooner or later, 5G is going to introduce a new face of AR and AI applications with access to higher quality videos and multiplayer games in real-time. It will also enable a wide range of advanced technologies that involve machine-to-machine (M2M) communication and transforms the way people lead their lives.
One of the biggest security challenges that 5G networks possess is privacy. The 5G network introduces various kinds of applications and allows connecting more devices to the network. It somehow encourages capturing and sharing the exceeding amount of personal data, including the ones that are already captured digitally before. There are times when people store extremely personal data like details about their bodies and wellbeing in case of an eHealth application. On the other hand, connected car services can track every movement, and smart city applications can collect information about the lifestyle. The total number of related objects can trigger data collection.
Nevertheless, since 5G is designed as the first generation of mobile connectivity having M2M communication, connected devices will be able to interact with many sensors in the coherent world. Every step or function is an opportunity to harvest more data.
The enhanced volume and variety of data can make it more valuable for the attackers who have immoral intentions. The possibility of blackmail, identity theft, and personal safety gets potentially endless. Since 5G requires more network sites to reimburse for reduced range, the location data given by the operators might get more accurate and can provide the hackers with the exact address of the information. In the meantime, the improved numbers of connected devices are nothing but the potential targets and launch pads for the hackers. In case a device is not connected correctly, then it can lead the way for cybercriminals to steal the data or initiate a widespread attack throughout the network.
5G networks consist of three chief elements, which are—the radio, the transport, and the core network. Out of which, the core is considered to be the most sensitive part of the network as it handles the central customer data. The debate regarding privacy threats in the media has become prominent when it comes to 5G. Along with the higher amount of data conveyed across the network, including the mission-critical applications that are dependent on 5G, the chances of an attack also get increasingly unpleasant. Risky infrastructure is a significant reason to consider when it comes to security threats. Mobile operators, keeping in mind the issue, are making sure that security is installed into the 5G network fabric.
It is significant to identify the reason that makes people assume that 5G networks can be any less secure than 4G. In fact, not a single mobile network comes completely foolproof, but is considerably safer than connecting and using public Wi-Fi.
Network slicing is available with 5G that helps the operators protect different parts of their network, dedicated to specific users or applications. The technology brings higher speed and abilities as well as restricts the use of the bandwidth by anyone else.
Mobile operators are ensuring that their services are secured at every possible infrastructure level, as people consider the security and reliability of a network while selecting a provider.
