Autenticación de usuario local mediante clave precompartida (procedimiento de CLI)
Visión general
En esta configuración, se utilizan el nombre de usuario y la contraseña para la autenticación de usuario local. Esta opción de configuración no le permite cambiar o recuperar sus credenciales sin interactuar con el administrador del firewall, por lo que no recomendamos este método de autenticación. En su lugar, se recomienda utilizar el método de autenticación de usuario externo mediante RADIUS .
Suponemos que ha completado la configuración básica de los firewalls de la serie SRX, incluidas las interfaces, las zonas y las políticas de seguridad, como se ilustra en la figura 1.
Figura 1: Topología
Para obtener información acerca de los requisitos previos, consulte Requisitos del sistema para Juniper Secure Connect.
Debe asegurarse de que el firewall de la serie SRX utiliza un certificado firmado o un certificado autofirmado en lugar del certificado predeterminado generado por el sistema. Antes de empezar a configurar Juniper Secure Connect, debe enlazar el certificado al firewall de la serie SRX ejecutando el siguiente comando:
user@host# set system services web-management https pki-local-certificate <cert_name>
Por ejemplo:
user@host# set system services web-management https pki-local-certificate SRX_Certificate
Donde SRX_Certificate es el certificado autofirmado.
Configuración rápida de CLI
Para configurar rápidamente este ejemplo en los firewalls de la serie SRX, copie los siguientes comandos, péguelos en un archivo de texto, elimine los saltos de línea, cambie los detalles necesarios para que coincidan con su configuración de red y, a continuación, copie y pegue los comandos en la CLI en el nivel de jerarquía [editar].
