Identificar e remediar riscos através de APIs de proteção de identidade

Microsoft Entra ID Protection oferece às organizações informações sobre riscos e métodos baseados em identidade para investigar e remediar automaticamente estes riscos. Este tutorial orienta-o ao longo da utilização de APIs de Proteção de ID para identificar riscos e configurar fluxos de trabalho para confirmar compromissos ou ativar a remediação.

Neste tutorial, vai aprender a utilizar as APIs de Proteção de IDs para:

Gere um início de sessão de risco.
Permitir que os utilizadores com inícios de sessão de risco remediam o risco status com uma política de Acesso Condicional que requer autenticação multifator (MFA).
Bloquear o início de sessão de um utilizador com uma política de Acesso Condicional.
Dispensar um risco de utilizador.

Pré-requisitos

Para concluir este tutorial, certifique-se de que tem:

Um inquilino Microsoft Entra com uma licença P1 ou P2 Microsoft Entra ID.
Acesso a um cliente de API, como o Graph Explorer, com sessão iniciada com uma conta que tenha a função Administrador de Acesso Condicional.
As seguintes permissões delegadas: IdentityRiskEvent.Read.All, IdentityRiskyUser.ReadWrite.All, Policy.Read.All, Policy.ReadWrite.ConditionalAccess e User.ReadWrite.All.
Uma conta de utilizador de teste para iniciar sessão numa sessão anónima para acionar uma deteção de risco. Utilize uma sessão de navegação privada ou o browser Tor. Neste tutorial, a alcunha de correio de utilizador de teste é MyTestUser1.

Passo 1: Acionar uma deteção de risco

Na sessão anónima do browser, inicie sessão no centro de administração do Microsoft Entra como MyTestUser1.

Passo 2: Listar deteções de risco

Quando MyTestUser1 iniciou sessão no centro de administração do Microsoft Entra através do browser anónimo, foi detetado um anonymizedIPAddress evento de risco. Pode utilizar o $filter parâmetro de consulta para obter apenas as deteções de risco associadas à conta de utilizador MyTestUser1 . Poderá demorar alguns minutos para que o evento seja devolvido.

Passo 3: Criar uma política de Acesso Condicional

As políticas de Acesso Condicional permitem aos utilizadores remediar-se automaticamente quando é detetado um risco, permitindo-lhes aceder em segurança aos recursos depois de concluir o pedido de política. Neste passo, irá criar uma política de Acesso Condicional que exige que os utilizadores iniciem sessão com a MFA se ocorrer uma deteção de risco médio ou elevado.

Configurar a autenticação multifator

Ao configurar uma conta para a MFA, escolha o melhor método de autenticação para a sua situação.

Inicie sessão no site manter a sua conta segura com a conta MyTestUser1 .
Conclua o procedimento de configuração da MFA com o método adequado para a sua situação, como utilizar a aplicação Microsoft Authenticator.

Criar a política de Acesso Condicional

A política de Acesso Condicional permite-lhe definir condições para identificar níveis de risco de início de sessão. Os níveis de risco podem ser low, medium, highou none. O exemplo seguinte mostra como exigir a MFA para inícios de sessão com níveis de risco médios e elevados.

Ao iniciar sessão no browser anónimo, é detetado um risco, mas corrija-o ao concluir a MFA.

Inicie sessão no entra.microsoft.com com a conta MyTestUser1 e conclua o processo de MFA.

Passo 5: Listar deteções de risco

Execute novamente o pedido no Passo 2 para obter a deteção de risco mais recente para a conta de utilizador MyTestUser1 . Uma vez que a MFA foi concluída no Passo 4, o riskState para este evento de início de sessão mais recente é agora remediated.

[Opcional] Bloquear o início de sessão do utilizador

Se preferir bloquear utilizadores associados a inícios de sessão de risco em vez de permitir a auto-remediação, crie uma nova política de Acesso Condicional. Esta política impedirá os utilizadores de iniciarem sessão se ocorrer uma deteção de risco médio ou elevado. A principal diferença da política no Passo 3 é que builtInControls está agora definido como block.

Com esta política de Acesso Condicional implementada, a conta MyTestUser1 está agora bloqueada de iniciar sessão devido a um nível de risco médio ou elevado de início de sessão.

Início de sessão bloqueado

Passo 6: Dispensar utilizadores de risco

Se acredita que o utilizador não está em risco e não quer impor uma política de Acesso Condicional, dispense manualmente o utilizador de risco, conforme mostrado no pedido seguinte. O pedido devolve uma 204 No Content resposta.

Depois de dispensar o utilizador de risco, pode executar novamente o pedido no Passo 2 e irá reparar que a conta de utilizador MyTestUser1 tem agora um nível de risco de none e um riskState de dismissed.
