Este documento descreve como configurar o ISE e o solicitante do Windows para o Encadeamento do Protocolo de Autenticação Extensível (EAP) com o TEAP.

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.
O TEAP é um método de protocolo de autenticação extensível baseado em túnel que estabelece um túnel seguro e executa outros métodos EAP sob a proteção desse túnel seguro.
A autenticação TEAP ocorre em duas fases após a troca inicial de solicitação/resposta de identidade EAP. Na primeira fase, o TEAP usa o handshake TLS para fornecer uma troca de chave autenticada e para estabelecer um túnel protegido. Uma vez que o túnel é estabelecido, a segunda fase começa com o peer e o servidor se engajando em mais conversas para estabelecer as autenticações e políticas de autorização necessárias.
O Cisco ISE 2.7 e posterior suporta o protocolo TEAP. Os objetos type-length-value (TLV) são usados dentro do túnel para transportar dados relacionados à autenticação entre o par EAP e o servidor EAP. A Microsoft introduziu o suporte para TEAP na versão 10.2004 do Windows lançada em maio de 2020.
O encadeamento EAP permite a autenticação do usuário e da máquina em uma sessão EAP/Radius, em vez de duas sessões separadas. Anteriormente, para fazer isso, era necessário ter o módulo Cisco AnyConnect NAM e usar EAP-FAST no solicitante do Windows, já que o solicitante nativo do Windows não oferecia suporte a isso. Agora, você pode usar o Windows Native Supplicant para executar o encadeamento EAP com ISE 2.7 com o uso de TEAP.
1. Você deve editar os Protocolos Permitidos para ativar o TEAP e o Encadeamento EAP.
2. Navegue até ISE > Política > Elementos de política > Resultados > Autenticação > Protocolos permitidos > Adicionar novo. Marque as caixas de seleção de encadeamento TEAP e EAP.

3. Crie um perfil de certificado e adicione-o à Sequência de Origem da Identidade.
4. Navegue até ISE > Administração > Identidades > Sequência de origem da identidade e escolha o Perfil de autenticação do certificado.

5. Você deve chamar esta sequência na Política de Autenticação.
6. Navegue até ISE > Policy > Policy Sets. Choose the Policy Set forDot1x > Authentication Policy e escolha a Identity Source Sequences criada na Etapa 3.

7. Agora, você deve modificar a Política de Autorização no Conjunto de Políticas Dot1x.
8. Navegue até ISE > Política >. Conjuntos de políticasEscolha o conjunto de políticas para Dot1x > Política de autenticação. Você deve criar duas regras. A primeira regra verifica se a máquina está autenticada, mas o usuário não. A segunda regra verifica se o usuário e a máquina estão autenticados agora.

9. Isso conclui a configuração no lado do servidor do ISE.
Defina a configuração da autenticação com fio neste documento.
1. Navegue até Painel de Controle > Central de Rede e Compartilhamento > Alterar Configurações do Adaptador e clique com o botão direito em Conexão LAN > Propriedades. Clique na guia Autenticação.
2. Clique na lista suspensa Autenticação e escolha Microsoft EAP-TEAP.

3. Clique no botão Settings ao lado de TEAP.

4. Em Client Authentication, escolha o método EAP para autenticação na Microsoft: Cartão inteligente de outro certificado.
5. Para cada menu suspenso do método EAP, clique no botão Configurar e modifique conforme o requisito e clique em OK.

6. Clique na guia Configurações Adicionais na parte inferior.

Você pode reinicializar a máquina com o Windows 10 ou sair e entrar. Quando a tela de login do Windows é exibida, a autenticação da máquina é acionada.
Nos logs dinâmicos, você verá anônimo, host/Administrador (este exemplo exibe o nome da máquina) no campo de identidade. Você vê anônimo porque você configurou suplicante para privacidade de identidade acima.
Ao fazer login no PC com credenciais, você verá os logs dinâmicos como Administrator@example.local, host/Administrador. Este é o encadeamento EAP onde a autenticação do usuário e da máquina ocorreu em uma sessão EAP.

Nos Detalhes do Log ao Vivo, as autenticações da máquina mostram apenas uma única NACRadiusUsername entrada, no entanto, a autenticação de usuário e máquina encadeada mostra duas entradas (uma para o usuário e outra para a máquina). Além disso, você verá na seção Authentication Details , que TEAP (EAP-TLS) foi usado para o Authentication Protocol. Se você usar MSCHAPv2 para autenticação de máquina e usuário, o protocolo de autenticação mostrará TEAP (Microsoft: Senha segura (EAP-MSCHAP v2.)




Você deve habilitar estas depurações no ISE:
