| Abstract Text | Cyberattacks are posing a threat to the continuity and success of organisations worldwide and the costs associated with cybersecurity skyrocketed in the last years, reaching USD 6.9 billion in 2021. Therefore, the need for appropriate cybersecurity has never been higher. While malicious parties are teaming up to collaborate and cooperate on attacks, it is only natural that defenders should also cooperate or collaborate with each other in order to detect vulnerabilities or mitigate attacks. Firstly, this work gives an overview of the current state of cybersecurity and important concepts, and frameworks are discussed. Subsequently, definitions for collaborative cybersecurity and cooperative cybersecurity are proposed. A taxonomy is presented that could serve as a good categorisation basis for the existing research. A survey of the literature is performed, leveraging the proposed taxonomy. Finally, key limitations, trends and challenges are identified. As shown, current approaches focus on vulnerabilities sharing, intrusion detection and access control. While challenges remain with regards to the right amount of transparency in cybersecurity and to public-private cybersecurity collaboration and cooperation. |
