 > All connections to Azure SQL Database and Azure SQL Data Warehouse require encryption (SSL/TLS) while data is in transit to and from the database. When you're authoring a pipeline by using JSON, add the encryption property and set it to **true** in the connection string. For Azure Storage, you can use **HTTPS** in the connection string.

+> To enable encryption in transit while moving data from Oracle follow one of the below options:
+> 1. In Oracle server, go to Oracle Advanced Security (OAS) and configure the encryption settings, which supports Triple-DES Encryption (3DES) and Advanced Encryption Standard (AES), refer [here](https://docs.oracle.com/cd/E11882_01/network.112/e40393/asointro.htm#i1008759) for details. ADF automatically negotiates the encryption method to use the one you configure in OAS when establishing connection to Oracle.
+> 2. In ADF, you can add EncryptionMethod=1 in the connection string (in the Linked Service). This will use SSL/TLS as the encryption method. To use this, you need to disable non-SSL encryption settings in OAS on the Oracle server side to avoid encryption conflict.
