Segurança da informação: estudo de caso sobre o vazamento de senhas - ano de 2017

Abstract

The use of passwords is important to restrict access, ensure confidentiality and authenticity, however, poorly crafted or constantly using a single password for the most varied services can compromise your privacy. The objective of this monograph is to perform an analysis of the passwords that were leaked in 2017 through a case study, showing its entropy and as a password even if encrypted, becomes weak if used for a keyword of few characters. The methodology used in this work is exploratory and explanatory, and was carried out through bibliographic and secondary sources, treated in a quantitative and qualitative way, arose from the need to analyze the disclosure of sensitive data on the Internet as personal passwords. As a result of this monograph, it was found how it is possible to calculate the strength of a password, that is, its entropy, which passwords should be memorized and how to create them in a more secure way, and how to use managers to create and secure random the other hundreds of services.
