If there are no effective countermeasures and known adversaries can exploit the asset, what is the vulnerability level?

When evaluating vulnerability levels in the context of adversary capabilities and the effectiveness of countermeasures, the absence of effective protective measures combined with the presence of known adversaries who can exploit the asset strongly indicates a critical vulnerability. This signifies that the asset is highly susceptible to threat actors who have the intent and capability to compromise it.

The term "critical" reflects that the situation poses an imminent and severe risk. It implies that immediate actions are necessary to mitigate the risk, as the asset is not adequately protected and is highly likely to be targeted and successfully exploited by adversaries. Organizations need to prioritize addressing critical vulnerabilities to maintain operational integrity and security.
