Logs CSF :Tentativa de Login SSH:


Andre Soares

Recommended Posts

Bom dia pessoal,

Instalei e configurei o CSF ontem e analisando os logs de bloqueio de IP verifiquei mtas tentativas de login ao SSH. É normal isso? Algo adicional que possamos fazer pra aumentar a segurança neste tipo de tentativa?

Edit: Troquei a porta SSH
