Description: Joint Cybersecurity Exercises are simulated scenarios involving multiple organizations aimed at testing and improving cybersecurity preparedness. These exercises are designed to replicate cyber-attack situations in a controlled environment, allowing organizations to assess their response capabilities and collaboration in the face of security incidents. In the context of ‘Zero Trust’ principles, these exercises focus on the premise that no entity, whether internal or external, should be trusted by default. This means that every access to resources must be verified and authenticated, regardless of the user’s location. Through these exercises, organizations can identify vulnerabilities in their security policies, improve communication among teams, and establish more effective response protocols. Additionally, they foster a collaborative cybersecurity culture, where lessons learned are shared among participating entities, thereby strengthening the collective security posture against cyber threats. In a world where attacks are becoming increasingly sophisticated, these exercises become essential to ensure that organizations are prepared to face the challenges of modern cybersecurity.
