Quando você sai de casa, fica sem acesso ao Wi-Fi que já conhece – e que já confia. Se você não tem acesso a uma conexão móvel, como 4G e 5G, surge a possibilidade de se conectar a redes de Wi-Fi de estabelecimentos, como cafés e aeroportos

Mas não se engane: essas conexões podem representar certo risco para a segurança do seu dispositivo. Redes de internet públicas estão disponíveis para qualquer um

Exemplo disso ocorre quando uma pessoa se utiliza de uma falha na rede pública para interceptar a conexão e desviar dados possivelmente sensíveis. Assim, o ideal seria evitar o uso desse tipo de rede

Se for inevitável entrar na rede pública de Wi-Fi, recomenda-se não fazer compras (ou seja, colocar dados de cartão de crédito ou outras formas de pagamento) ou realizar o download de documentos importantes ou que contenham informações sigilosas ao se usar esse tipo de conexão

Outra boa dica é a utilização de VPN no seu dispositivo móvel. O VPN codifica as informações do aparelho, fazendo com que elas sejam muito mais difíceis de acessar. Dessa forma, mesmo que um hacker intercepte a sua comunicação, os dados estarão criptografados
