Thus, with the increasing number of cyber attacks, we have a large amount of threat data from heterogeneous sources that needs to be ingested, processed and analyzed in order to obtain useful insights for their mitigation. This study proposes a methodological framework to collect, organize, filter, share and visualize cyber-threat data to mitigate attacks and fix vulnerabilities, based on an eight-step cyber threat intelligence model with timeline visualization of threats information and analytic data insights. We developed a tool to address needs in which the cyber security analyst can insert threat data, analyze them and create a timeline to obtain insights and a better contextualization of a threat. Results show the facilitation of understanding the context in which the threats are inserted, rendering the mitigation of vulnerabilities more effective. 2076-3417 10.3390/app12031205 https://hdl.handle.net/20.500.14352/72082 https://doi.org/10.3390/app12031205 https://www.mdpi.com/2076-3417/12/3/1205/htm Methodological Framework to Collect, Process, Analyze and Visualize Cyber Threat Intelligence Data
