Summary  
This chapter covers the implementation of encryption protocols, authentication filters, and monitoring systems in code to protect data transmission and enforce access control, demonstrating how to integrate multi-layered security measures.  

General domain of usage  
Wireless network security

**Redes sem fio** oferecem flexibilidade e conveniência, mas também introduzem vulnerabilidades de segurança adicionais em comparação com redes cabeadas. Proteger redes sem fio envolve o uso combinado de **criptografia**, **controle de acesso** e **monitoramento** para mitigar esses riscos e garantir que os dados permaneçam protegidos.

Por que é importante alterar o SSID e a senha padrão de um roteador sem fio?
