5G: Security Features and Concerns


From UPSC perspective, the following things are important :

Prelims level: 5G

Mains level: 5G, Security and challenges


Central Idea

  • With the arrival of 5G technology, all electronic devices will potentially be connected to the internet. Cyber damage scenarios, imagined only in dystopian fiction, could become a reality. A collaborative approach between the government, academia, and businesses is necessary to address these cyber security concerns and ensure that 5G technology is safe and secure for consumers.

What exactly is 5G?

  • Latest advancement: 5G, or fifth-generation wireless technology, is the latest advancement in mobile communication and internet technology.
  • Higher frequency spectrum: 5G operates on a higher frequency spectrum than 4G, typically between 24 GHz to 90 GHz. This higher frequency range allows for faster data transfer rates and lower latency.
  • MIMO technology: 5G uses a technology called MIMO (Multiple Input Multiple Output) to transmit and receive multiple data streams simultaneously. This allows for greater capacity and faster speeds.
  • Network slicing: It also utilizes network slicing, which enables the creation of multiple virtual networks on a single physical network. This allows for more efficient use of network resources and can improve overall network performance.
  • Applications: 5G technology is expected to enable the development and implementation of emerging technologies such as self-driving cars, virtual and augmented reality, and smart cities.

Security Features of 5G Technology

  • Security-by-Design Approach: 5G technology is designed with a security-by-design approach that embeds security features from the beginning. This approach ensures that security is an integral part of the technology, rather than an afterthought.
  • Strong Encryption Standards: 5G technology incorporates strong encryption standards that make it extremely difficult for attackers to access and use any information they might obtain. Even if an attacker manages to obtain some information, it will be in an unusable format.
  • Interconnected Device Protection: 5G technology also includes protocols that protect the confidentiality of interconnected devices. These protocols prevent unauthorized access and ensure that data transmitted between devices remains secure and private.


What are the Concerns?

  • Inheriting past vulnerabilities: The initial wave of 5G will be built on existing 4G infrastructure, therefore, it will inherit vulnerabilities of the past.
  • Multiplying privacy concerns: More devices connected to the internet increase the scope of cyber-attacks. In a connected network, such attacks can spread like wildfire if not contained in time. Privacy concerns are bound to multiply as the number of devices increases.
  • Concerns about pre-ban imported equipment: A bulk of 5G network components have been imported and manufactured in factories based in China. Imports of such equipment have been banned. However, concern remains about the use of the equipment that was imported before the ban came into effect.
  • For instance, concerns over user privacy: Many countries including the USA and Canada have expressed concerns over protocols used by Huawei and ZTE that compromise the privacy of users.

What can be done to Ensure 5G Security

  • Collaborative efforts between government, academia, and businesses: Governments should work with industry experts and academia to develop comprehensive security measures and policies that align with the rapidly evolving technological landscape.
  • Ongoing security testing: Telecom companies should perform regular security testing of their 5G infrastructure to identify vulnerabilities and address them before they can be exploited by attackers. Telecom companies and ethical hackers can be invited to test infrastructure.
  • For instance: C-DOT’s 5G alliance focuses on security aspects, it needs to be scaled up as a Center of Excellence involving IITs and CERT-In.
  • Reward mechanisms: Offering incentives to 5G service providers who adhere to high security standards can promote better security practices across the industry.
  • Consumer education: Government agencies like CERT-In can publish easy-to-understand advisories to educate end-users on best practices to protect themselves and their devices from potential security breaches.
  • Greater responsibility: All stakeholders must assume greater responsibility to protect the 5G ecosystem from cyber threats.
  • International cooperation: International cooperation between governments and organizations can help establish global standards and guidelines for 5G security, promoting greater consistency and transparency in security practices.


  • Consumers are at the heart of the 5G ecosystem and need to be aware of the security challenges. Exciting times await us in 2023. All stakeholders need to prepare for the security challenges of the 5G package.
