Considering a career in network security?

There are multiple ways to get started in this field. I recommend starting with OSI and TCP/IP layer model which makes you understand better. Apart from that, the concepts of network hierarchy, DMZ, ports, and protocols should be clear enough to start the network security field.

Eu comecei com redes lendo livros e praticando. Apliquei muito em testes e produ??o. Meu divisor de águas foi o CCNA da Cisco. Garanto por mais que você esteja avan?ado, voltará à base para reaprender conceitos. E isso será aplicado em seguran?a redes de borda, DMZ, IDS, ajuste fino para detec??o e mitiga??o de ataques. Domine o modelo OSI e entenda todo o conceito da implementa??o TCP/IP em sistemas operacionais diversos. Criptografia é outra base fundamental. Estude Diffie–Hellman (DH) e outros algoritmos que s?o fundamentais para a prote??o de comunica??es. Estude algoritmos de integridade novos mas n?o deixe de entender porque alguns est?o obsoletos e o que é hash collision.

Network security is a rapidly growing field with high demand and excellent job prospects.
