The world has never been more connected than it is today. The Internet has become critical to our everyday lives, for businesses and individuals, and so too has its security. With our growing dependence on networked digital systems comes an increase in the variety and scale of threats and cyber attacks.

A variety in the protective methods used by countries or organizations can make it difficult to assess risk systematically and to ensure consistent, adequate security.

Therefore, standards have a key role to play in improving cybersecurity – protecting the Internet, its communications and the businesses that rely on it – and TC CYBER is the most security-focused technical committee in ETSI.

Our Role & Activities

TC CYBER is recognized as a major trusted centre of expertise offering market-driven cyber security standardization solutions, advice and guidance to users, manufacturers, network, infrastructure and service operators and regulators. ETSI TC CYBER works closely with stakeholders to develop standards that increase privacy and security for organizations and citizens across Europe and worldwide. We provide standards that are applicable across different domains, for the security of infrastructures, devices, services, protocols, and to create security tools and techniques.

Some of our latest standards have been in network security (implementing the NIS Directive TR 103 456, the Middlebox Security Protocol TS 103 523 series, a survey of network gateways TR 103 421), cryptography for access control and personally identifying information (Attribute-Based Encryption TS 103 458 and TS 103 532), Critical Security Controls (the TR 103 305 series), protecting PII in line with GDPR (TR 103 370), Quantum-Safe Key Exchanges (TR 103 570), and more. You can see a full list on our standards page.

The Quantum-Safe Cryptography working group is a subgroup of TC CYBER; you can find out more about their work.

In addition to TC CYBER, other pdfETSI groups also work on standards for cross-domain cybersecurity, the security of infrastructures, devices, services and protocols and security tools and techniques. They address the following areas and more information can be found in the related technologies pages:
