5G application complex network security issues cannot be ignored

The commercial use of 5G has brought unlimited possibilities and promoted the development of high-tech industries. However, innovative technologies will inevitably give rise to new network security risks, bringing a certain degree of concerns to consumers.

5G services involve a multi-supplier environment, including various types of 5G service providers, including 5G equipment providers, mobile network operators, cloud service providers and third-party application developers. In addition, the 5G network itself is constructed by multiple types of networks and uses various connection technologies, which may lead to the risk of personal data and privacy being leaked. Therefore, the application of 5G also brings more network security issues that cannot be ignored.

5G networks not only serve individual consumers, but more importantly, they expand services to vertical markets, including healthcare, smart homes, and smart transportation, providing products or services to customers in a certain industry and bringing richer business development.

In addition, 5G also brings about a globalized mobile Internet of Things, connecting businesses around the world. Different businesses will have different security requirements to meet different purposes, such as supporting low energy consumption requirements or efficient mobility security mechanisms. Therefore, 5G service providers need to provide flexible and efficient, end-to-end security protection, be able to respond to changes in business and scenarios, quickly update security protection mechanisms, and eliminate any potential threats.

Although the emergence of 5G technology has changed the online world and brought new and unimaginable applications, the security issues it brings cannot be ignored. The security of 5G networks will always be the primary consideration for consumers to use 5G, and it is also an important factor driving the continuous development of 5G. 5G service providers should work together to continuously strengthen security solutions through technological innovation, formulate security standards to manage and control risks, and jointly build a secure and reliable 5G network to give consumers a shot in the arm.

Information security in the 5G era is not at the same level and concept as that in the 4G era. This requires both the establishment of institutional standards at the national level and the advancement of technology. The application scenarios of 5G are completely different. The access of a large number of application scenarios such as the Internet of Things and autonomous driving will make the amount of data and the importance of security in the fields involved after the full application of 5G far greater than the 4G era when it was mainly used for communication technology. The transmission density of 5G is about 100 times higher than that of 4G. The number of terminals supported per square kilometer is also higher than that of 4G. At the same time, the upload speed of 5G is also relatively high. Therefore, big data and the Internet of Things will give 5G a boost.

In the future, 5G will have industrial-level applications and city-level applications. Sensors in nuclear power plants may be connected by 5G, and connected cars on the road may be connected by 5G. Once the network is attacked, you will find that the consequences may be much more serious than they are now.

In the era of 5G Internet and big data, the entire security landscape has changed, so traditional security protection is no longer effective.

To put it simply, the network security belt will no longer adopt this fragmented, single-point defense or blocking. Instead, it will establish a big data-driven platform to collect all possible problems in the entire 5G network or the entire industrial Internet network, all network security incidents that have occurred or may occur, and all network security data. In this way, big data and data accumulation will form a "knowledge base" and "database" about network attacks to discover threat points and risk points, form threat intelligence, and then use threat intelligence to connect isolated and out-of-phase network security products at each node in the entire network, realizing true connectivity, coordinated defense, and in-depth protection.
