It was analyzed certain information about cyberattacks in Latin America and methods to counteract the aggressions that affect services, data and infrastructure. The problem is the cyberattack on information networks where there is interdependence between processes, people and devices within public organizations with the negative consequence of denial of services. The objective is to propose a protection model against cyberattacks in public organizations in Latin America to minimize the denial of public services. It was applied the deductive method and exploration to examine the information of cited articles. It resulted a General Model of Protection against Attacks, a Prototype of a network, a Algorithm in flowchart to minimize the attack arrival and a Formula of probability of attack arrival. It was concluded that in order to maintain the continuity of services and activities of public organizations, secure platforms must be in place to monitor and minimize possible attacks; our proposal has an attack detection accuracy of 87.49%.
