Azure Active Directory (Azure AD) sirve como el servicio basado en la nube de Microsoft para la gestión de identidades y accesos. Es fundamental para permitir que los empleados inicien sesión y accedan a recursos, tanto dentro como fuera de la organización, abarcando Microsoft 365, el portal de Azure y una multitud de otras aplicaciones SaaS. El diseño de Azure AD se centra en ofrecer servicios de identidad esenciales, incluyendo autenticación, autorización y gestión de usuarios.
Las características clave de Azure AD incluyen autenticación multifactor y acceso condicional, junto con una integración fluida con otros servicios de seguridad de Microsoft. Estas características elevan significativamente la seguridad de las identidades de los usuarios y permiten a las organizaciones implementar y hacer cumplir sus políticas de acceso de manera efectiva. Como un componente fundamental del ecosistema de servicios en la nube de Microsoft, Azure AD es crucial para la gestión basada en la nube de identidades de usuarios.

Connect-AzureAD -AccountId test@corp.onmicrosoft.com -AadAccessToken $tokenCuando inicias sesión a través de CLI en Azure con cualquier programa, estás utilizando una Aplicación de Azure de un inquilino que pertenece a Microsoft. Estas Aplicaciones, como las que puedes crear en tu cuenta, tienen un id de cliente. No podrás ver todas ellas en las listas de aplicaciones permitidas que puedes ver en la consola, pero están permitidas por defecto.
Por ejemplo, un script de powershell que autentica utiliza una aplicación con id de cliente 1950a258-227b-4e31-a9cf-717495945fc2. Incluso si la aplicación no aparece en la consola, un sysadmin podría bloquear esa aplicación para que los usuarios no puedan acceder utilizando herramientas que se conectan a través de esa App.
Sin embargo, hay otros ids de cliente de aplicaciones que te permitirán conectarte a Azure:

Una cadena secreta que la aplicación utiliza para probar su identidad al solicitar un token es la contraseña de la aplicación. Así que, si encuentras esta contraseña puedes acceder como el service principal dentro del tenant. Ten en cuenta que esta contraseña solo es visible cuando se genera (puedes cambiarla pero no puedes obtenerla de nuevo). El propietario de la aplicación puede agregar una contraseña a ella (para que pueda suplantarla). Los inicios de sesión como estos service principals no se marcan como riesgosos y no tendrán MFA.
Es posible encontrar una lista de IDs de aplicaciones comúnmente utilizadas que pertenecen a Microsoft en https://learn.microsoft.com/en-us/troubleshoot/entra/entra-id/governance/verify-first-party-apps-sign-in#application-ids-of-commonly-used-microsoft-applications

Si un dispositivo (VM) está unido a AzureAD, los usuarios de AzureAD podrán iniciar sesión. Además, si el usuario que ha iniciado sesión es Propietario del dispositivo, será administrador local.

La Gestión de Identidades Privilegiadas (PIM) en Azure ayuda a prevenir que se asignen privilegios excesivos a los usuarios innecesariamente.
Una de las principales características proporcionadas por PIM es que permite no asignar roles a los principales que están constantemente activos, sino hacerlos elegibles por un período de tiempo (por ejemplo, 6 meses). Luego, cada vez que el usuario quiera activar ese rol, necesita solicitarlo indicando el tiempo que necesita el privilegio (por ejemplo, 3 horas). Luego, un administrador necesita aprobar la solicitud. Tenga en cuenta que el usuario también podrá solicitar extender el tiempo.
Además, PIM envía correos electrónicos cada vez que se asigna un rol privilegiado a alguien.
Cuando PIM está habilitado, es posible configurar cada rol con ciertos requisitos como:
Duración máxima (horas) de activación
Requerir MFA en la activación
Requerir contexto de autenticación de Acceso Condicional
Requerir justificación en la activación
Requerir información de ticket en la activación
Requerir aprobación para activar
Tiempo máximo para expirar las asignaciones elegibles
Mucha más configuración sobre cuándo y a quién enviar notificaciones cuando ocurren ciertas acciones con ese rol

La Protección de Identidad de Entra es un servicio de seguridad que permite detectar cuando un usuario o un inicio de sesión es demasiado arriesgado para ser aceptado, permitiendo bloquear al usuario o el intento de inicio de sesión.
Permite al administrador configurarlo para bloquear intentos cuando el riesgo es "Bajo y superior", "Medio y superior" o "Alto". Aunque, por defecto está completamente deshabilitado:
Hoy en día se recomienda agregar estas restricciones a través de políticas de Acceso Condicional donde es posible configurar las mismas opciones.
La Protección de Contraseñas de Entra (https://portal.azure.com/#view/Microsoft_AAD_ConditionalAccess/PasswordProtectionBlade) es una característica de seguridad que ayuda a prevenir el abuso de contraseñas débiles al bloquear cuentas cuando ocurren varios intentos de inicio de sesión fallidos. También permite prohibir una lista de contraseñas personalizadas que necesita proporcionar.
Se puede aplicar tanto a nivel de nube como en Active Directory local.
El modo predeterminado es Auditoría:
