The purpose of the master's thesis is the process of hunting the cyber threat inside an organization and how an organization can develop it with open-source tools. All the necessary tools for the application of the proactive cyber defense are installed and the tactics, techniques and procedures used by cyber attackers are presented, as well as the different models for identification and prevention of cyber intrusions activity. Tools include the collection of information about cyber threats and the security operations center that includes the organization, analysis and specialization of threat information related to possible or ongoing cyber-attacks that target an organization. As a result, we will have an infrastructure that will detect, collect, and organize cyber threat incidents.
