Verified Access 信任資料的第三方信任提供者內容

本節說明第三方信任提供者提供給 AWS Verified Access 的信任資料。

瀏覽器延伸模組

如果您打算將裝置信任內容納入存取政策，則需要 AWS Verified Access 瀏覽器延伸模組或其他合作夥伴的瀏覽器延伸模組。Verified Access 目前支援 Google Chrome 和 Mozilla Firefox 瀏覽器。

我們目前支援三個裝置信任提供者：Jamf （支援 macOS 裝置）、CrowdStrike （支援 Windows 11 和 Windows 10 裝置） 和 JumpCloud （同時支援 Windows 和 MacOS)。

Jamf

Jamf 是第三方信任提供者。評估政策時，如果您將 Jamf 定義為信任提供者，Verified Access 會在 Cedar 內容中，在您指定為信任提供者組態上「政策參考名稱」的金鑰下包含信任資料。您可以選擇撰寫評估信任資料的政策。下列 JSON 結構描述顯示評估中包含哪些資料。

如需搭配 Verified Access 使用 Jamf 的詳細資訊，請參閱 Jamf 網站上的將 AWS Verified Access 與 Jamf Device Identity 整合。

            }
        },
        "risk": {
            "type": "string",
            "enum": [
                "HIGH",
                "MEDIUM",
                "LOW",

        }
    }
}

以下是針對 Jamf 提供的信任資料進行評估的政策範例。

permit(principal, action, resource) when {
   context.jamf.risk == "LOW"
};

Cedar 提供實用的.contains()函數，可協助處理列舉，例如 Jamf 的風險分數。

permit(principal, action, resource) when {
   ["LOW", "SECURE"].contains(context.jamf.risk)
};

CrowdStrike

CrowdStrike 是第三方信任提供者。評估政策時，如果您將 CrowdStrike 定義為信任提供者，Verified Access 會在 Cedar 內容中，在您在信任提供者組態上指定為「政策參考名稱」的金鑰下包含信任資料。您可以選擇撰寫評估信任資料的政策。下列 JSON 結構描述顯示評估中包含哪些資料。
