Provisionar o Secure Firewall ASA para CSM

Introdução

Este documento descreve o processo para provisionar o Secure Firewall Adaptive Security Appliance (ASA) para o Cisco Security Manager (CSM).

Pré-requisitos

Requisitos

A Cisco recomenda que você tenha conhecimento destes tópicos:

• ASA com firewall seguro
• CSM

Componentes Utilizados

As informações neste documento são baseadas nestas versões de software e hardware:

• Secure Firewall ASA versão 9.18.3
• CSM versão 4.28

As informações neste documento foram criadas a partir de dispositivos em um ambiente de laboratório específico. Todos os dispositivos utilizados neste documento foram iniciados com uma configuração (padrão) inicial. Se a rede estiver ativa, certifique-se de que você entenda o impacto potencial de qualquer comando.

Informações de Apoio

O CSM ajuda a permitir a aplicação consistente de políticas e a rápida solução de problemas de eventos de segurança, oferecendo relatórios resumidos em toda a implantação de segurança. Usando sua interface centralizada, as organizações podem escalar com eficiência e gerenciar uma ampla variedade de dispositivos de segurança da Cisco com visibilidade aprimorada.

Configurar

No próximo exemplo, um ASA virtual é provisionado para um CSM para gerenciamento centralizado.

Configurações

Configurar ASA para Gerenciamento HTTPS

Etapa 1. Crie um usuário com todos os privilégios.

Sintaxe da linha de comando (CLI):

configure terminal
username < user string > password < password > privilege < level number >

Isso se traduz no próximo exemplo de comando, que tem o usuário csm-user e a senha cisco123 da seguinte maneira:

ciscoasa# configure terminal
ciscoasa(config)# username csm-user password cisco123 privilege 15

Etapa 2. Habilite o servidor HTTP.

Sintaxe da linha de comando (CLI):

configure terminal
http server enable

Etapa 3. Permitir acesso HTTPS para o endereço IP do servidor CSM.

Sintaxe da linha de comando (CLI):

configure terminal
http < hostname > < netmask > < interface name >

Isso se traduz no próximo exemplo de comando, que permite que qualquer rede acesse o ASA através de HTTPS na interface externa (GigabitEthernet0/0):

ciscoasa# configure terminal
ciscoasa(config)# http 0.0.0.0 0.0.0.0 outside

Etapa 4. Valide se o HTTPS pode ser acessado do servidor CSM.

Abra qualquer navegador da Web e digite a próxima sintaxe:

https://< ASA IP address >/

Isso se traduz no próximo exemplo para o endereço IP da interface externa que foi permitido para acesso HTTPS na etapa anterior:

https://10.8.4.11/

Resposta ASA HTTPS

Provisionar o Secure Firewall ASA para CSM

Etapa 1. Abra e faça login no cliente CSM.

Logon do cliente CSM

Etapa 2. Abra o Gerenciador de configurações.

Painel do cliente CSM

Etapa 3. Navegue até Devices > New Device.

Gerenciador de configuração do CSM

Etapa 4. Selecione a opção de adição que preenche o requisito de acordo com o resultado desejado. Como o ASA configurado já está configurado na rede, a melhor opção para este exemplo é Add Device From Network e clique em Next.

Método de Adição de Dispositivo

Etapa 5. Preencha os dados necessários de acordo com a configuração no Secure Firewall ASA e com as configurações de detecção. Em seguida, clique em Next.

Configurações do ASA

Etapa 6. Preencha as credenciais necessárias do usuário CSM configurado no ASA e da senha de ativação.

Credenciais do ASA

Passo 7. Selecione os grupos desejados ou ignore esta etapa se nenhum grupo for necessário e clique em Finish.

Seleção de grupo CSM

Etapa 8. Uma solicitação de tíquete é gerada para fins de controle, clique em OK.

Criação de tíquete CSM

Etapa 9. Valide se a descoberta termina sem erros e clique em Fechar.

Descoberta do ASA

Etapa 10. Valide se o ASA agora aparece como registrado no cliente CSM e exibe as informações corretas.

Informações do ASA registradas

Verificar

Uma depuração HTTPS está disponível no ASA para fins de solução de problemas. O próximo comando é usado:

debug http

Este é um exemplo de uma depuração de registro de CSM bem-sucedida:
