Configuring Ws-Man for Maximum Security

Oracle ILOM provides a standard, web-services interface for monitoring the health of the server and providing inventory information using a protocol called Ws-Management (Ws-Man). The Oracle ILOM Ws-Man interface also allows for peer control of the host and for resetting the Oracle ILOM SP itself. Ws-Man is a Simple Object Access Protocol (SOAP)-based protocol, leveraging the HTTP(S) protocols. The Oracle ILOM Ws-Man interface can be used with either HTTP or HTTPS as a transport. If HTTPS is used, the channel is encrypted using an SSL certificate. For information about the security benefits of using SSL certificates, as well as the difference between self-signed versus trust certificates, see Using SSL Certificates.

Use this web-services interface only if SSL certificates are being used. For maximum security, use HTTPS as the transport mechanism. For information about changing from HTTP to HTTPS as a transport for Ws-Man, see the Oracle ILOM 3.1 Protocol Management Reference Guide.
