The Data Integration Service can include a web service security header when it sends a SOAP request to the web service provider. The web service security header contains authentication information so the web service provider can authenticate the Data Integration Service. You can use the following types of web service security in a web services connection:

PasswordText. The Data Integration Service does not change the password in the WS-Security SOAP header.
PasswordDigest. The Data Integration Service combines the password with a nonce and a time stamp. The Data Integration Service applies a SHA hash on the password, encodes it in base64 encoding, and uses the encoded password in the SOAP header.

Security implemented on top of the transport layer (TCP layer) of TCP/IP using Secure Sockets Layer (SSL). Web services use Hypertext Transfer Protocol over SSL (HTTPS) as a web address for secure message transport. Web Service Consumer transformations can use TLS 1.2, TLS 1.1, or TLS 1.0. You can use the following authentication with transport layer security: HTTP authentication, proxy server authentication, and SSL certificates.

You can use SSL authentication when you connect through the HTTPS protocol.

You can use the following types of SSL authentication:

One-way SSL authentication
Two-way SSL authentication

You can use HTTP authentication when you connect through the HTTP protocol.

You can use the following HTTP authentication methods:

Basic authentication
Digest authentication
NT LAN Manager (NTLM) authentication
