an alternate, secure method to manage your machine (such as physical access

 

to the console or a secure terminal server) or if you do not use Secure Shell.

Description

Web-Based Enterprise Management (WBEM) is a Distributed Management

 

Task Force (DMTF) industry standard, http(s)-based management protocol

 

which features encryption and authentication. It is much better than SNMP,

 

which has a history of security issues and is by default a clear-text,

 

unauthenticated protocol. Like SNMP, WBEM can be a powerful aid in

 

managing multiple machines and it is by default much more secure. However,

 

any service can be a security risk, so you should block it if you are not going

 

to use it.

Description

Port 1188 is used by web-based tools that are replacements for areas of SAM.

 

The listener on this port is the HP release of Apache with a custom

 

configuration file that loads only a minimum set of modules. It is also restricted

 

to use https for all communication and can only be used to run the system

 

management tools. In general, this web server is running only when in use.

 

It exits after a period of inactivity. Disabling this port means that some system

 

administration functions are only available using the command line.
