Vulnerabilidade em redes de computadores corporativas: estudos de caso sobre ataques de ransomware

Abstract

The main objective of this work was to deepen the understanding of the challenges faced by corporate networks in terms of cybersecurity, with a special focus on the threat of ransomware attacks. To carry out this work, the bibliographic research method was used, using relevant and reliable sources. As for the results, several types of Ransomware attacks were identified, and the main ones are: Scareware, Petya, Doxware, Cerber, Ryuk, SQL Injection, Phishing and Sniffing. And the main points of vulnerability are: lack of awareness and adequate training of employees, weak security protocols and lack of good practices in application development. The results allowed us to conclude that there is no single solution to prevent attacks and solve all the company's vulnerability problems. However, there are several efficient forms of protection and good practices, such as employee training and maintaining widespread security policies within the organization. Furthermore, knowing what the main types of attacks are and how cybercriminals act are factors in keeping the company protected against cyberattack
