Validação baseada em certificados usando autenticação EAP-MSCHAPv2 (Procedimento CLI)
Visão geral
Nesta configuração, você usa o nome de usuário e a senha para autenticação externa do usuário (por servidor RADIUS) e usa o método de autenticação EAP-MSCHAPv2 para validar os certificados de usuário.
Presumimos que você tenha concluído a configuração básica de seus firewalls da Série SRX, incluindo interfaces, zonas e políticas de segurança, conforme ilustrado na Figura 1.
Figura 1: Topologia
Para obter informações sobre pré-requisitos, consulte os requisitos do sistema.
Garanta que você tenha uma infraestrutura de chave pública (PKI) configurada como a autenticação de back-end. Nesse caso, você só precisa instalar o certificado raiz do CA em cada cliente. Observe que a autenticação local não é suportada neste cenário.
Você deve garantir que o firewall da Série SRX use um certificado assinado ou um certificado auto-assinado em vez do certificado padrão gerado pelo sistema. Antes de começar a configurar o Juniper Secure Connect, você deve vincular o certificado ao firewall da Série SRX executando o seguinte comando:
user@host# set system services web-management https pki-local-certificate <cert_name>
Por exemplo:
user@host# set system services web-management https pki-local-certificate SRX_Certificate
Onde SRX_Certificate está o certificado auto-assinado.
Configuração rápida da CLI
Para configurar rapidamente este exemplo em seus firewalls da Série SRX, copie os seguintes comandos, cole-os em um arquivo de texto, remova quaisquer quebras de linha, altere todos os detalhes necessários para combinar com sua configuração de rede e, em seguida, copie e cole os comandos na CLI no nível de hierarquia [editar].
