Security
HP WBEM Services supports four connection points
• HTTP port
• HTTPS (HTTP Secure) port
• HTTPS port for Export Connections
• a 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 CIM Clients and the CIM Server. The port defined
by the service name wbem-exp-https (HTTPS TCP/IP communication) is dedicated
for CIM-XML communication between the Indication sender and the CIM Server
(Indication receiver). The HTTP and the two HTTPS connection points may 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
Keep in mind the following security considerations if you plan to make use of SNMP
as well as PRM and WLM:
• You can use tools such as Process Resource Manager (PRM) and Workload Manager
(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,
may constantly reach its limits, causing undesirable results.
• Due to known security vulnerabilities and limitations of the SNMP protocol, we
do not recommend the utilization of the SNMP indication handler.
