A community generally consists of all of the entities within a geographical region, including both public and private infrastructures. Cyber attacks and other cyber threats can result in disruption and destruction of critical services and cause potentially devastating impacts in a community. \ \ An effective information collection, sharing and incident collaboration and coordination process is needed in communities to detect potential risks, prevent cyber attacks at an early stage, and facilitate incident response and preparedness activities. In this paper, an expanded collaborative information sharing framework that aims to improve community cyber security is presented. An Information Sharing Maturity Model is developed as a roadmap with evolutionary procedures and incremental steps for community organizations to advance in information sharing maturity.10 pagesengAttribution-NonCommercial-NoDerivatives 4.0 Internationalcyber securityinformation sharinginformation securitycritical infrastructuresmaturity modelConference Paper10.24251/HICSS.2017.287
