A problem shared is a problem halved: A survey on the dimensions of collective cyber defense through security information sharing

Information has grown at such a fast pace that we are converging ever quicker into a state of interconnectedness that requires more collaboration and organized efforts between all parties who have a stack in the digital realm. Since there is more information to be processed, to be shared, information sharing is a great concern for defense in cybersecurity. The information sharing is not only a technical issue, but also an issue of legal, regulatory and organizational matters. Organizations such as countries and companies are incentivized to put together a more orchestrated effort to keep up with the increase in the number and intensity of cyber attacks. Current (and suggested) improvements include the use of AI/ML to automate and augment some technical aspects of defense, adoption of a set of standard practices (e.g. NIST cybersecurity framework) among nation-states via open-source tools, and more data collection on every incident.
