Q: Which TLS Version Should I Use?

2023-08-14

The minimum TLS protocol for HTTPS connections is now displayed in ADM settings. If the TLS protocol version used by a browser does not meet the security settings, a connection will not be established.

TLS 1.0 will no longer be supported for security reasons.

ADM 4.0 and above supports TLS 1.1, 1.2 and 1.3.
ADM 3.5.9.RRS1 and above supports TLS 1.1 and 1.2.

After enabling HTTPS connection in Settings under General, select the appropriate minimum TLS protocol version for HTTPS connections according to your needs:

1. TLS 1.1: Allow connections using TLS 1.1, 1.2 or 1.3.
   • Compatible with most browsers such as Chrome, Firefox, Edge, Safari and all ASUSTOR apps.
   • Contains minimal security.
2. TLS 1.2: Allow connections using TLS 1.2 or 1.3, this is the system default.
   • Compatible with most browsers such as Chrome, Firefox, Edge, Safari.
   • Compatible with most ASUSTOR apps.
   • Surveillance Center not yet supported.
3. TLS 1.3: Only allow connections using TLS 1.3.
   • Compatible with modern browsers including, but not limited to Chrome, Firefox, Edge, Opera and Safari.
   • Compatible with Android 10 and above, iOS 12.5 and above.
   • Listed below are apps that cannot connect with HTTPS at this moment in time:
     • ASUSTOR EZ Sync (AES) Windows
     • Surveillance Center
   • Known issues for iOS apps currently being worked on:
     • AiFoto3 is not able to play back video files from a NAS using an HTTPS connection.
     • AiMusic is not able to play back audio files from a NAS using an HTTPS connection.
     • AiData is not able to play back video files from a NAS using an HTTPS connection.
     • AiSecure is not able to play back surveillance recordings from a NAS using an HTTPS connection.

TLS 1.3 is not enabled in Windows 10 by default. Setting the minimum TLS protocol for HTTPS connections in ADM settings 1.3 means it will only accept connections using TLS 1.3. Connections using TLS 1.2 or below will be unable to connect. Please click here to learn how to enable TLS 1.3 in Windows 10 to increase security when connecting to your NAS.
