Security
HP WBEM Services supports the following connection points:
• HTTP port
• HTTPS (HTTP Secure) port
• HTTPS port for Export Connections
• UNIX domain socket for local connections
HP WBEM Services uses dedicated ports for CIM-XML traffic. The ports 5988 (HTTP TCP/IP
communication) and 5989 (HTTPS TCP/IP communication) are dedicated for CIM-XML
communications between the CIM clients and the CIM Server. The port wbem-exp-https (HTTPS
TCP/IP communication) is dedicated for CIM-XML communication between the Indication sender
and the CIM Server. The HTTP point and the two HTTPS connection points can be disabled using
the cimconfig command line utility. However, the UNIX domain socket connection is always
enabled when the CIM Server is running.
Security considerations
When you use the Simple Network Management Protocol (SNMP), Process Resource Manager
(PRM), and Workload Manager (WLM) tools, consider the following security conditions:
• You can use tools such as PRM and WLM to limit computing resources used by the WBEM
Services processes. You can purchase these products from http://www.software.hp.com.
However, limiting or restricting the computing resources of the WBEM Services processes,
depending on the configured limits and WBEM Services utilization, can cause WBEM Services
processes to constantly reach the limits.
• Due to security limitations of the SNMP protocol, HP does not recommend using the SNMP
indication handler.
SSL support
HP WBEM Services uses SSL (Secure Sockets Layer) for all communications, with server-side
certificates that are trusted by the management application, when using HTTPS connections. HP
WBEM Services uses OpenSSL to support HTTPS connections.
