The fifth generation of mobile wireless technology (5G), brings more speed, faster communications, and the ability to connect to many more devices at the same time. However, security in 5G networks is still a challenge.

But what does this mean for data protection and privacy?

The fact that 5G supports many different access networks, including 2G, 3G, 4G, and Wi-Fi, means that the new technology may inherit all the security challenges of the networks before it.

5G is the first mobile architecture designed to support multiple specific use cases, each with its own unique cybersecurity requirements.

This poses a major security risk in 5G networks.

For example, 5G will enable IoT applications on a massive scale, such as traffic sensors and vehicle-to-infrastructure services, and is the basis for smart cities.

It is critical that cybercriminals cannot access data, hijack IoT devices, or perform distributed denial-of-service attacks in smart city scenarios.

In fact, security in 5G networks is nothing new for the mobile industry. There is a long-standing importance on security, creating a strong market differentiation from other wireless technologies, some of which have vulnerable network architectures.

Security in 5G networks and authentication must go hand in hand

Today’s networks face a wide variety of threats from different sources and attack routes. The quantity and quality of these attacks increase every year as more points of vulnerability become available in networks and devices.

With IoT at scale, the threat surface becomes quite broad, especially when it comes to services, applications, platforms, networks, and the IoT devices themselves.

In practice, cybercriminals understand the vulnerability of threats related to mobility, edge, and network cores, firewalls, and other interfaces present many opportunities for attack.

Each vulnerability point potentially presents several different types of threats, such as message blocking, denial of service, man-in-the-middle techniques, and more, that can attack authentication, integrity, network availability, and privacy.

With so many exposure points and vulnerability threats, security can significantly strain the resources of the 5G network operator

Fortunately, wireless carriers don’t have to reinvent the wheel. The protocols and security specifications in 5G networks are based on and compatible with the main frameworks developed in 4G.

In addition, 5G offers new security features that use multi-network slicing, multi-tier services, and multiple connectivity capabilities.

To enable the necessary flexibility, agility, and economies of scale, these technologies will be delivered through virtual and containerized environments.

This is a revolutionary way of working for the industry.

The development of 5G standards has adopted ‘Secure by Design’ principles, considering:

• Use of mutual authentication: Confirm that the sender and recipient have an established trust and the end-to-end relationship is guaranteed;
• An alleged “open” network: removal of any assumption of safety of the overlapping product(s) or process(es);
• An acknowledgement that all links can be accessed: Enforce encryption of inter/intra-network traffic, ensuring that encrypted information is worthless when intercepted.

While this is a common practice in solutions for other services, such as Internet Banking, it is a major paradigm shift for existing mobile telecommunications practices.

As a consequence, 5G networks should offer the consumer more protection than existing 4G/3G/2G networks.

Security in 5G Networks: Protecting Users and Devices

Security in 5G networks improves the confidentiality and integrity of user and device data.

Unlike previous generations of 5G mobile systems:

• Protects the confidentiality of messages between the device and the network: as a result, it is no longer possible to trace the user’s equipment using current attack methodologies on the radio interface, protecting against attacks
  man in the middle
  ;
• It introduces a protection mechanism called home control: this means that the final authentication of the device to a visited network is completed after the home network checks the authentication status of the device and the connection used. This enhancement will prevent various types of fraud that have historically harmed carriers and address the carrier’s need to properly authenticate devices to services;
• Supports unified authentication in other types of access networks: allowing 5G networks to manage previously unmanaged and unsecured connections. This includes the ability to perform re-authentication when the device moves between different access or service networks;
• Introduces user plan integrity checking: ensuring that user traffic is not modified during transit;
• Enhances privacy protection by using public/private key pairs to hide the subscriber’s identity and derive keys used throughout the service architecture. to hide the subscriber identity and derive keys used throughout the service architecture.

The goal of 5G is to open up the network to a broader set of services and allow mobile operators to support these services. It is an opportunity to protect services and consumers from many of today’s threats.

In practice, 5G comes with many built-in security controls by design, designed to enhance the protection of individual consumers and mobile networks, this is more effective than post-deployment add-ons or extras.

The advancement of technology and the use of new architectures and features, such as network slicing, virtualization, and cloud, will introduce new threats that require new types of controls to be implemented.

Ericsson and Thales partner to offer a solution for secure 5G authentication and user privacy

One of the key components of a reliable 5G network is the integrity of the virtualized infrastructure and the confidentiality of the data flowing within it.

Protecting and authenticating subscriber authentication and privacy presents several challenges, including infrastructure complexity, the distributed nature of 5G networks, the large number of connected IoT devices, the use of multi-vendor networks, and the evolution of 3G and 4G connections.
