TS EN ISO 22300

TS EN ISO 22300 is a vocabulary standard for the security and resilience field. Its main value lies in giving organisations, public bodies and service providers a shared language so that closely related concepts such as risk, incident, preparedness, continuity and recovery are understood more consistently.

Why the terms are defined separately

Security and resilience bring together concepts that are linked in practice but not identical. In general technical usage, security is more closely associated with preventing, reducing or controlling threats, while resilience is concerned with the ability of an organisation, community or system to continue functioning, adapt and recover after an event. That distinction matters because incident management, business continuity, protection measures and crisis response may use similar words with different operational meanings.

What this vocabulary standard provides

The document covers the definition of terms related to security and resilience; in other words, it is intended to clarify the language used in this domain. Vocabulary standards are widely used to reduce ambiguity in technical documents, procedures, training material and multi-stakeholder communication. TS EN ISO 22300 therefore serves as a reference for consistent terminology rather than prescribing a specific method or testing regime.

As an EN ISO 22300:2025-based vocabulary standard, this listing is especially useful for users who need a reliable conceptual framework for security and resilience terminology. It supports common understanding across sectors where the same words can otherwise carry different meanings.
