適用於:Applies to:

想要體驗 Microsoft 365 Defender 嗎?Want to experience Microsoft 365 Defender? 您可以在實驗室環境中評估在生產環境中執行試驗專案You can evaluate it in a lab environment or run your pilot project in production.

Microsoft 365 Defender (https://security.microsoft.com) 結合了保護、偵測 調查,以及對 電子郵件、共同作業、身分 識別裝置 威脅的回應,集中入口網站。Microsoft 365 Defender (https://security.microsoft.com) combines protection, detection, investigation, and response to email, collaboration, identity, and device threats, in a central portal.

Microsoft 365Defender 會將現有 Microsoft 安全性入口網站的功能彙集在一起,如 Microsoft Defender 資訊安全中心和 Office 365 安全性 & 規範中心。Microsoft 365 Defender brings together functionality from existing Microsoft security portals, like Microsoft Defender Security Center and the Office 365 Security & Compliance center. [安全性中心] 強調快速存取訊號、簡化版面配置,以及將相關資訊放在一起,以方便使用。The security center emphasizes quick access to information, simpler layouts, and bringing related information together for easier use. 此中心包括:This center includes:

  • Microsoft Defender Office 365 適用于 Office 365 的 Microsoft Defender 可協助組織使用一組預防、偵測和搜尋功能保護其企業,以保護電子郵件,並 Office 365 資源。Microsoft Defender for Office 365 Microsoft Defender for Office 365 helps organizations secure their enterprise with a set of prevention, detection, investigation and hunting features to protect email, and Office 365 resources.
  • Microsoft Defender For Endpoint 會為組織中的裝置提供預防性保護、入侵後偵測、自動調查和回應。Microsoft Defender for Endpoint delivers preventative protection, post-breach detection, automated investigation, and response for devices in your organization.
  • Microsoft 365 Defender 是 Microsoft 的 延伸偵測和回應 (XDR) 解決方案的一部分,利用 Microsoft 365 的安全性產品群組,可以自動分析跨網域的威脅資料,並在單一儀表板上建立攻擊的圖片。Microsoft 365 Defender is part of Microsoft’s Extended Detection and Response (XDR) solution that leverages the Microsoft 365 security portfolio to automatically analyze threat data across domains, and build a picture of an attack on a single dashboard.

注意

Microsoft 365 安全性入口網站會使用並強制執行現有的角色型存取,並將每一種安全性模型移至統一入口網站。The Microsoft 365 security portal uses and enforces existing roles-based access, and will move each security model into the unified portal. 每個收斂工作負載 (例如 MDO 或 MDE) 具有自己的角色型存取權。Each converged workload (such as MDO or MDE) has its own roles-based access. 產品中已有的角色將會自動收斂至 Microsoft 365 的安全性入口網站。The roles already in the products will be converged into the Microsoft 365 security portal, automatically. 不過,MCAS 的角色和許可權仍會在 MCAS 中處理。However, roles and permissions for MCAS will still handled over in MCAS.

預期的專案What to expect

在 Office 365 安全性與合規性中心 (protection.office.com) 和 Microsoft Defender security center (securitycenter.microsoft.com) 中所使用的所有安全性內容,現在都可以在 Microsoft 365 Defender 中找到。All the security content that you use in the Office 365 Security and Compliance Center (protection.office.com) and the Microsoft Defender security center (securitycenter.microsoft.com) can now be found in the Microsoft 365 Defender.

Microsoft 365Defender 可協助安全小組調查和回應攻擊,方法是將不同工作負載的信號引入一組整合體驗:Microsoft 365 Defender helps security teams investigate and respond to attacks by bringing in signals from different workloads into a set of unified experiences for:

  • 事件 & 警示Incidents & alerts
  • 搜捕Hunting
  • 控制中心Action center
  • 威脅分析Threat analytics

Microsoft 365當合併 microsoft defender for Office 365 和 microsoft defender for Endpoint 時,Defender 強調 unity、清晰度及共同目標Microsoft 365 Defender emphasizes unity, clarity, and common goals as it merges Microsoft Defender for Office 365 and Microsoft Defender for Endpoint. 合併是以下列所列的優先順序為基礎,而不犧牲每個安全性套件所加入的功能:The merge was based on the priorities listed below, and made without sacrificing the capabilities that each security suite brought to the combination of:

  • 萬用群組建區塊Common building blocks
  • 常見術語Common terminology
  • 一般實體Common entities
  • 與其他工作負載的功能同位Feature parity with other workloads

注意

Microsoft 365您不需要讓客戶進行遷移步驟或購買新的授權,即可存取 Defender。Microsoft 365 Defender will be accessible without any need for customers to take migration steps or purchase a new license. 例如,具有 E3 訂閱的系統管理員可以存取這個新入口網站,就像使用 Microsoft Defender 做為 Office 365 方案1和方案2一樣)。不過,Exchange Online Protection 或 MDO Plan 1 客戶只會看到其訂閱授權所支援的安全性功能。For example, this new portal will be accessible to administrators with an E3 subscription, just as it is to those with Microsoft Defender for Office 365 Plan 1 and Plan 2; however, Exchange Online Protection, or MDO Plan 1 customers will see only the security features their subscription license supports. 新的中心目標是集中安全性。The goal of the new center is to centralize security.

整合調查Unified investigations

彙聚安全性中心建立單一位置,以用於調查各 Microsoft 365 的安全性事件。Converging security centers creates a single place for investigating security incidents across Microsoft 365. 主要範例是 Microsoft 365 Defender 的快速啟動上之 事件 & 警示事件A primary example is Incidents under Incidents & alerts on the quick launch of Microsoft 365 Defender.

Microsoft 365 Defender 中的 [事件] 頁面。

選取 [事件名稱] 會顯示一個頁面,其中會示範「整合」安全中心的價值。Selecting an incident name displays a page that demonstrates the value of converging security centers.

Microsoft 365 Defender 中的事件摘要頁面範例

在 [事件] 頁面的頂端,您會看到 摘要警示裝置使用者信箱調查證據 索引標籤。Along the top of an incident page, you'll see the Summary, Alerts, Devices, Users, Mailboxes, Investigations, and Evidence tabs. 如需詳細資訊,請選取這些索引標籤。Select these tabs for more detailed information. 例如,[使用者] 索引標籤會顯示聚合工作負載 (microsoft defender for Endpoint、microsoft defender 身分識別及 Microsoft Cloud App Security) 和來源範圍(如內部部署 Active Directory 網域服務 (AD DS) 、Azure Active Directory (Azure AD) 和協力廠商身分識別提供者)的使用者資訊。For example, the Users tab displays information for users from converged workloads (Microsoft Defender for Endpoint, Microsoft Defender for Identity, and Microsoft Cloud App Security) and a range of sources such as on-premises Active Directory Domain Services (AD DS), Azure Active Directory (Azure AD), and third-party identity providers. 如需詳細資訊,請參閱 調查使用者For more information, see investigate users.

花時間複習您環境中的事件、深入查看這些索引標籤,並練習如何針對不同類型的威脅存取針對事件所提供的資訊。Take the time to review the incidents in your environment, drill down into these tabs, and practice building an understanding of how to access the information provided for incidents for different kinds of threats.

如需詳細資訊,請參閱Microsoft 365 Defender 中的事件For more information, see incidents in Microsoft 365 Defender.

改進的處理常式Improved processes

常見的控制項和內容會出現在相同的位置,或是壓縮成一個資料摘要,使其更容易尋找。Common controls and content either appear in the same place, or are condensed into one feed of data making it easier to find. 例如,統一設定。For example, unified settings.

統一設定Unified settings
