Segurança de TI: defesa contra as artes negras digitais from Coursera

Este curso abrange uma grande variedade de conceitos, ferramentas e práticas recomendadas ao nível da segurança de TI. Aborda ameaças e ataques e as várias formas através das quais podem surgir. Vamos fornecer-lhe algumas informações gerais sobre o que são os algoritmos de encriptação e como são utilizados para salvaguardar dados. Em seguida, vamos analisar detalhadamente os três aspetos mais importantes da segurança das informações: autenticação, autorização e contabilidade. Também vamos abordar soluções de segurança de rede, desde firewalls a opções de encriptação de Wi-Fi. Por último, vamos analisar um caso prático, no qual examinamos o modelo de segurança do Chrome OS. O curso conclui ao reunir todos estes elementos numa arquitetura de segurança detalhada e de várias camadas, apresentando depois recomendações sobre como integrar uma cultura de segurança na sua entidade ou equipa.

No final deste curso, vai saber mais sobre:

● como funcionam vários algoritmos e técnicas de encriptação, bem como as respetivas vantagens e limitações

● vários tipos e sistemas de autenticação

● a diferença entre autenticação e autorização

● como avaliar potenciais riscos e recomendar formas de reduzir o risco

● práticas recomendadas para proteger uma rede

● como ajudar as outras pessoas a entender conceitos de segurança e a protegerem-se
