停用 Office 365 GCC 高和 DoD 中的 TLS 1.0 和1。1Disabling TLS 1.0 and 1.1 in Office 365 GCC High and DoD


為了遵守聯邦風險和授權管理計畫的最新符合性標準 (FedRAMP) ,我們會停用 Microsoft 365 中的傳輸層安全性 (TLS) 版本1.1 和1.0,以供 GCC 高及 DoD 環境使用。In order to comply with the latest compliance standards for the Federal Risk and Authorization Management Program (FedRAMP), we are disabling Transport Layer Security (TLS) versions 1.1 and 1.0 in Microsoft 365 for GCC High and DoD environments. 這項變更先前是透過 Microsoft 支援宣告的,以 準備在 Office 365 中強制使用 TLS 1.2This change was previously announced through Microsoft Support in Preparing for the mandatory use of TLS 1.2 in Office 365.

您的資料安全性很重要,我們承諾對可能影響服務使用的變更進行透明性。The security of your data is important, and we are committed to transparency about changes that could affect your use of the service.

雖然 MICROSOFT TLS 1.0 的執行 沒有已知的安全性弱點,但仍然會繼續致力於 FedRAMP 規範標準。Although the Microsoft TLS 1.0 implementation has no known security vulnerabilities, we remain committed to the FedRAMP compliance standards. 因此,我們停用 Office 365 中的 TLS 1.1 和1.0,在2020年1月15日 DoD 環境中。Therefore, we disabled TLS 1.1 and 1.0 in Office 365 in GCC High and DoD environments on January 15, 2020. 如需如何移除 TLS 1.1 和1.0 相依性的相關資訊,請參閱下列白皮書:For information about how to remove TLS 1.1 and 1.0 dependencies, see the following white paper:

解決 TLS 1.0 問題Solving the TLS 1.0 problem

詳細資訊More information

從2020年1月15日開始,在 GCC 高端和 DoD 環境中的 Office 365 會取代 TLS 1.1 及1.0。Starting on January 15, 2020, Office 365 in the GCC High and DoD environments will deprecate TLS 1.1 and 1.0.

在2020年1月15日,所有用戶端伺服器與瀏覽器伺服器的組合都應該使用 TLS 版本 1.2 (或更新版本) ,以確保所有連線都不會向 Office 365 服務提出任何問題。By January 15, 2020, all combinations of client servers and browser servers should use TLS version 1.2 (or a later version) to make sure that all connections can be made without issues to Office 365 services. 這可能需要更新用戶端伺服器與瀏覽器伺服器的某些組合。This may require updates to certain combinations of client servers and browser servers.

如果您未更新為 TLS 版本 1.2 (或更新版本) (2020年1月15日),當您嘗試連線到 Office 365 時,您會遇到問題。If you do not update to TLS version 1.2 (or a later version) by January 15, 2020, you will experience issues when you try to connect to Office 365. 此外,您必須更新為 TLS 1.2 (或更新版本) 做為解決方法的一部分。Additionally, you will be required to update to TLS 1.2 (or a later version) as part of the resolution.

您必須更新用戶端電腦,以確保您維護 Office 365 GCC 高和 DoD 的不間斷存取。You must update your client computers to make sure that you maintain uninterrupted access to Office 365 GCC High and DoD.

您必須更新透過 TLS 1.0 或 TLS 1.1 呼叫 Microsoft 365 APIs 的應用程式,才能使用 TLS 1.2。You'll need to update applications that call Microsoft 365 APIs over TLS 1.0 or TLS 1.1 to use TLS 1.2. .NET 4.5 的預設值為 TLS 1.1。.NET 4.5 defaults to TLS 1.1. 若要更新您的 .NET 設定,請參閱 如何在用戶端上啟用傳輸層安全性 (TLS) 1.2To update your .NET configuration, see How to enable Transport Layer Security (TLS) 1.2 on clients. 如需詳細資訊,請參閱 在 Office 365 中準備 TLS 1.2 的強制使用For more information, see Preparing for the mandatory use of TLS 1.2 in Office 365.

我們知道下列用戶端應用程式無法使用 TLS 1.2:We know that the following client applications cannot use TLS 1.2:

  • Android 4.3 和舊版Android 4.3 and earlier versions
  • Firefox 5.0 和舊版Firefox version 5.0 and earlier versions
  • Internet Explorer 8 – 10 on Windows 7 及更早版本Internet Explorer 8–10 on Windows 7 and earlier versions
  • Windows Phone 8.0 上的 Internet Explorer 10Internet Explorer 10 on Windows Phone 8.0
  • Safari 6.0.4/OS X 10.8.4 及更早版本Safari 6.0.4/OS X 10.8.4 and earlier versions

[!附注] 目前對 Microsoft Online services 連線的分析顯示,大部分的服務和端點請參閱極少的 TLS 1.1 和1.0 使用量,我們會提供這項變更的通知,讓您在支援 TLS 1.1 和1.0 結束之前,依照需要更新任何受影響的用戶端或伺服器。Although current analysis of connections to Microsoft Online services shows that most services and endpoints see very little TLS 1.1 and 1.0 usage, we're providing notice of this change so that you can update any affected clients or servers as necessary before support for TLS 1.1 and 1.0 ends. 如果您使用任何內部部署基礎結構的混合案例或 Active Directory Federation Services (AD FS) ,請確定基礎結構可以支援使用 TLS 1.2 (或更新版本) 的輸入和輸出連線。If you are using any on-premises infrastructure for hybrid scenarios or Active Directory Federation Services (AD FS), make sure that the infrastructure can support both inbound and outbound connections that use TLS 1.2 (or a later version).

除了當您使用無法使用 TLS 1.2 的列出用戶端時,您可能會遇到的停機情形,移除 TLS 1.1 及1.0 將會使您無法使用下列 Microsoft 產品:In addition to the outages that you might experience if you use the listed clients that cannot use TLS 1.2, removing TLS 1.1 and 1.0 will prevent you from being able to use the following Microsoft product:

  • Lync phoneLync phone
