Análise prática e estudo dos impactos provocados pelas principais vulnerabilidades do OWASP top 10 2021

Abstract

The internet has provided the emergence of several applications for the most diverse purposes, encompassing users from all over the world. However, as its growth occurs, new vulnerabilities also appear, which compromise the security of these users, who spontaneously provide personal data trusting that the system will keep them safe. However, the lack of knowledge and preparation causes this data to be received, transferred, accessed or manipulated insecurely, exposing sensitive information and harming everyone involved. In this way, with the aim of alerting and instructing to keep applications safe, OWASP (Open Web Application Security Project), an international institution focused on web security, periodically publishes lists with the most frequent and harmful vulnerabilities that most affected web applications in a certain time interval. Thus, the objective of this work is to analyze and demonstrate each of the vulnerabilities proposed by OWASP in the 2021 list, using laboratories to exemplify the risks and impacts of the main current vulnerabilities.
