5.  Security Considerations

   Certain management information defined in this MIB may be considered
   sensitive in some network environments.  Therefore, authentication of
   received SNMP requests and controlled access to management
   information SHOULD be employed in such environments.  An
   authentication protocol is defined in [12].  A protocol for access
   control is defined in [15].  It is a customer responsibility to
   properly set up access control for MIB access.



Clouston & Moore            Standards Track                    [Page 16]

RFC 2584              APPN/HPR in IP Networks MIB               May 1999


   None of the read-only objects in this 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.

   The one read-write and four read-create objects in the MIB can affect
   network operations; it is recommended that SNMP access to these
   objects be restricted.  The five objects are:

   o    hprIpPortTOSPrecedence:  Setting this object immediately changes
        the mapping for all link stations using this port which do not
        have an entry to override the port value.  Improper mappings may
        cause delays or disruptions in the network.  For example, if
        APPN traffic type 'High' is mapped to IP TOS Precedence bits '
        001', network control traffic will have the same TOS precedence
        as bulk data traffic.  This may cause delays with session
        initializations, and timeouts on control sessions that could
        cause network outages.

   o    hprIpLsTOSPrecedence:  Setting this object has the potential for
        delay or disruption for this link station as described above
        with hprIpPortTOSPrecedence.

   o    hprIpLsRowStatus:  Setting this object to delete(6) causes this
        link station to revert to the default TOS Precedence mapping for
        its port.  The customized mapping for this link station will no
        longer be in effect.

   o    hprIpCnTOSPrecedence:  Setting this object has the potential for
        delay or disruption for this links created for this connection
        network as described above with hprIpPortTOSPrecedence.

   o    hprIpCnRowStatus:  Setting this object to delete(6) causes links
        created for this connection network to revert to the default TOS
        Precedence mapping for its port.  The customized mapping for
        this connection network will no longer be in effect.
