HP WBEM Services for HP-UX and Linux System Administrator's Guide

Security Considerations
User Authentication
Chapter 6 63
an authenticated user - with privileged access to the system running
WBEM Services - will be allowed to issue requests to HP WBEM Services
from a remote system.
When HP WBEM Services installs, the CIM Server will be configured
with a randomly-generated, self-signed certificate. If a self-signed server
certificate does not give a sufficient level of trust, the system
administrator can use a central Certificate Authority ( e.g. Verisign) to
issue certificates.
When HP WBEM Services for Linux gets installed, a "wbem" file is
installed in the /etc/pam.d directory. This file will list the PAM security
modules used for HP WBEM Services. The System Administrator may
change the contents to conform to the security requirements of the
managed system.
