Description: Joint incident response in the context of Zero Trust security refers to the collaboration between different entities, such as organizations, security teams, and technology providers, to address and mitigate cybersecurity incidents. This approach is based on the premise that no entity should automatically trust any other, regardless of its location within or outside the network. Joint response involves sharing critical information about threats, vulnerabilities, and attack tactics, enabling security teams to act more effectively and swiftly in the face of incidents. Key features of this approach include effective communication among participants, the use of tools and technologies that facilitate collaboration, and the implementation of standardized protocols for incident management. The relevance of joint response lies in the increasing complexity and sophistication of cyberattacks, which require a coordinated and multifaceted response to be effectively neutralized. In a Zero Trust environment, where trust is minimal and constantly verified, collaboration becomes an essential element to strengthen organizations’ security posture and reduce response time to incidents.
