8.  Security Considerations

   In most cases, MIBs are not themselves security risks; if SNMP
   security is operating as intended, the use of a MIB to view
   information about a system, or to change some parameter at the
   system, is a tool, not a threat.




Clouston & Moore            Standards Track                    [Page 33]

RFC 2238         Definitions of Managed Objects for HPR    November 1997


   None of the read-only objects in the HPR MIB reports a password, user
   data, or anything else that is particularly sensitive.  Some
   enterprises view their network configuration itself, as well as
   information about network usage and performance, as corporate assets;
   such enterprises may wish to restrict SNMP access to most of the
   objects in the MIB.

   One read-write object in the MIB can affect network operations:

   o    hprRtpPathSwitchTrigger:  Setting this object to 'switchPathNow'
        triggers an immediate path switch attempt.  An HPR path switch
        does not itself disrupt the SNA sessions using the RTP
        connection undergoing the path switch.  However, frequent path
        switches for many RTP connections can have an adverse impact on
        overall network performance.

        It is recommended that SNMP access to this object be restricted.

        Other read-write objects control the gathering of network
        management data; controlling access to these objects is less
        critical.
