ChangeAuditor for Active Directory

Active Directory 변경 감사

퀘스트 ChangeAuditor for Active Directory는 실시간으로 원시 감사에 오버헤드를 일으키지 않고 핵심적인 설정 변화를 능동적으로 추적, 감사, 보고 및 경고합니다. 변경 사항의 주체, 내용, 시간, 위치, 워크스테이션 번호를 파악할 수 있습니다. 또한, 기존값과 현재값을 비교하여 신속히 문제를 해결할 수 있습니다. ChangeAuditor for AD는 감사자와 관리자에게 지능형 세부 정보를 생성하여 일일 변경 사항과 관련된 위험 요인을 줄입니다.

  • 일목요연한 표시:모든 변경 사항에 대한 기본값과 현재값을 포함한 주체, 대상, 시기, 장소, 워크스테이션 및 변경 이벤트 이유를 포함한 세부 정보를 이용하여 사용자 및 관리자 활동을 확인합니다
  • 실시간 "스마트" 경보: 핵심 항목이 변경되거나 변경 패턴이 발생하면 즉시 경보를 보내 관리자가 지체없이 대응할 수 있습니다. 
  • 계정 잠금: 계정 잠금 이벤트를 위한 최초 IP 주소/워크스테이션명을 파악하여 문제 해결 과정을 단순화 단순화합니다.
  • 개체 보호: 실수로 삭제된 OU 및 수정된 GPO 설정과 같이 가장 중요한 AD 개체의 변경을 방지합니다.
  • 중첩 그룹 멤버쉽에 대한 변경 추적:명시적인 규칙을 세우지 않고 그룹 내에 존재하는 그룹을 모니터하여 그룹 변경 모니터를 간소화합니다.
  • 기본 감사 불필요: 기본 감사 로그 없이 변경 정보를 파악하여 스토리지 자원을 크게 절약합니다.
  • 설정 가능한 감사: 이벤트를 비활성화하고 높은 트래픽을 배제하여 안전한 계정이 감사에 포함되도록 하지 않도록 하여 감사용 데이터베이스의 오버로드를 방지합니다.
  • 보고: 내장된 보고 및 포괄적인 준수 보고 라이브러리 기능을 사용하여 사전 정의 또는 사용자 정의된 보고서를 신속하게 생성합니다.
  • 역할 기반 액세스: 애플리케이션 구성을 변경하거나 관리자의 수고와 시간을 낭비하지 않고 감사자가 검색하고 보고할 수 있도록 액세스를 구성합니다.

The user account that will be performing the coordinator installation needs to have the appropriate permissions to perform the following tasks on the target server:
    • Windows permissions to create and modify registry values.
    • Windows administrative permissions to install software and stop/start services.
* It is recommended that the user account performing the installation, be a member of the Domain Admins group in the domain where the coordinator is being installed.

Quest ChangeAuditor Agent (Server-side component)

A ChangeAuditor Agent can be deployed to domain controllers (DCs) and member servers to monitor the configuration changes made on these servers. These agents will then report these audit events to the SQL database or ChangeAuditor Coordinator.
Agent Hardware
  • Minimum: PIII 1.0 GHz or better; 512 MB RAM or better
    Recommended: P4 2.0 GHz or better; 2 GB RAM or better
  • Server running on any x86 or x64 editions of the following minimum platforms:
      • Windows Server 2003 SP1
      • Windows Server 2003 R2
      • Windows Server 2008
      • Windows Server 2008 Core
      • Windows Server 2008 R2
      • Windows Server 2008 R2 Core
  • ChangeAuditor Agent requires File and Printer Sharing on Windows Server 2008. By default, File and Printer sharing is not enabled on Windows Server 2008 installations. In order to remotely deploy agents to Windows Server 2008 (Full UI and Server Core), enable the File and Printer sharing (SMB-in) Inbound rule in the Windows Firewall (Port 445) on the target host machine.
  • The File and Printer Sharing for Microsoft Networks service on the network adapter must also be enabled for remote deployment.
  • Auditing of some Exchange events require the latest Exchange service pack to be installed. Please refer to the ChangeAuditor for Exchange Events Reference Guide for the minimum service packs required for Exchange events.
  • The ChangeAuditor Agent uses the COM+ and Distributed Transaction Coordinator (DTC) services locally on the host server for detecting Exchange Server message created, moved, copied and deleted events. If the COM+ or DTC services are disabled or inoperative, these events will not be detected but the Agent will otherwise run normally. Network access to DTC is not required. When enabling the COM+ service, a ChangeAuditor Agent restart is required, because COM+ service registration occurs at agent startup time.
Agent Software and Configuration
  • Microsoft .NET Framework 3.5 SP1 – ONLY where the agent is installed on Exchange servers with the CAS (OWA) role
  • Microsoft Data Access Components (MDAC) 2.8.
  • Requires an active Global Catalog
    ChangeAuditor Agents must be able to reach a global catalog (GC) server to resolve SIDs and mailbox names. If a GC is not available, the agent will temporarily use a DC to perform GC functions. The agent will attempt to connect to a GC every nine hours or on restart. The following events will not be captured while the GC is unavailable:
    • Exchange Mailbox events
    • Linked GPO changed events
    • QAS configuration events
Minimum Permissions
  • ChangeAuditor Agent must run as localsystem.
