Updated Cybersecurity Glossary to clarify the use of cybersecurity terms

On 11 May 2026, the National Cyber Security Office, based at the Ministry of Transport and Communications, and the Finnish Terminology Centre published an updated version of the Cybersecurity Glossary. The glossary project is part of the implementation plan of Finland’s Cyber Security Strategy 2024–2035.

The glossary was first published in 2018. It has now been brought up to date to reflect the changed operating environment. The update contains some 60 key cybersecurity concepts and definitions. The glossary also gives term equivalents in Swedish and English.

The objective of the Cybersecurity Glossary is to define key concepts related to cybersecurity, give recommendations on preferred terms and clarify the use of terms. The concepts are defined so that they can be used consistently in different contexts. 

The glossary is a tool for anyone working with cybersecurity, and it promotes the interoperability of information in public administration. The glossary will be available in the Sanastot (Terminologies) tool of the interoperability platform. It was drafted in extensive cooperation between authorities.

Finland’s Cyber Security Strategy makes cybersecurity a firmer part of comprehensive security

Finland’s Cyber Security Strategy was revised in 2024 in response to an evolving operating environment in accordance with the Programme of Prime Minister Petteri Orpo’s Government. Updating the Cybersecurity Glossary is one of the measures included in the strategy’s implementation plan.

The objectives of the Cyber Security Strategy extend to 2035. The aim is to make cybersecurity an integral part of Finland’s concept for comprehensive security. The strategy’s implementation plan describes the measures to achieve the objectives.
