By default, Microsoft Dynamics AX secures data sent across a network by using the remote procedure call (RPC) function RPC_C_AUTHN_LEVEL_CONNECT, which validates user credentials at the time a connection is established.

You can also encrypt data if your security needs require it. When you turn on encryption, Microsoft Dynamics AX uses the RPC_C_AUTHN_LEVEL_PKT_PRIVACY call, which provides the highest security level available through RPC.

For more information about RPC security, search for RPC security in MSDN: http://msdn.microsoft.com/.

Note Note

Enabling encryption may decrease performance between five and ten percent.

  1. Open the Microsoft Dynamics AX Configuration utility ( Start> Control Panel> Administrative Tools> Microsoft Dynamics AX Configuration Utility).

  2. Verify that the currently selected instance and configuration are the ones you want to modify.

  3. On the Connectiontab, click Encrypt client-to-server communications, and then click OK.
