Insecure Transport: Disabled App Transport Security

Swift

Abstract

部分或完全停用 App 傳輸安全性 (ATS) 可能會使應用程式暴露於網路攻擊之下。

Explanation

App 傳輸安全性 (ATS) 會針對安全網路連線 (例如 TLS 1.2) 和轉寄密碼強制執行最佳做法，並會在將來更新以反映 Apple 的網路最佳做法。

在 iOS 9 或 OS X El Capitan 中使用 NSURLSession、NSURLConnection 或 CFURL 時預設會啟用 App 傳輸安全性 (ATS)，從而會強制應用程式搭配使用 HTTPS 與 TLS 1.2 以用於與後端伺服器的所有網路通訊。

應用程式已設定為部分或全部退出 App 傳輸安全性 (ATS)，會使應用程式面臨遭受 man-in-the-middle 攻擊以及其他網路攻擊的風險。

範例 1：應用程式 Info.plist 中的以下項目會完全停用 App 傳輸安全性：


<key>NSAppTransportSecurity</key>
<dict>
  <!--Include to allow all connections (DANGER)-->
  <key>NSAllowsArbitraryLoads</key>
  <true/>
</dict>

範例 2：應用程式 Info.plist 中的以下項目將停用 yourserver.com 的 App 傳輸安全性：


<key>NSAppTransportSecurity</key>
<dict>
  <key>NSExceptionDomains</key>
  <dict>
    <key>yourserver.com</key>
    <dict>
      <!--Include to allow subdomains-->
      <key>NSIncludesSubdomains</key>
      <true/>
      <!--Allow plain HTTP requests-->
      <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
      <true/>
      <!--Downgrades TLS version-->
      <key>NSTemporaryExceptionMinimumTLSVersion</key>
      <string>TLSv1.1</string>
    </dict>
  </dict>
</dict>
