7.  Acknowledgments

   This MIB builds on all the work that has gone into the Informal
   Management Model for Differentiated Services Routers, Differentiated
   Services PIB, and Differentiated Services Policy MIB (SNMPCONF WG).

   It has been developed with the active involvement of many people, but
   most notably Yoram Bernet, Steve Blake, Brian Carpenter, Dave Durham,
   Michael Fine, Victor Firoiu, Jeremy Greene, Dan Grossman, Roch
   Guerin, Scott Hahn, Joel Halpern, Van Jacobsen, Keith McCloghrie, Bob
   Moore, Kathleen Nichols, Ping Pan, Nabil Seddigh, John Seligson, and
   Walter Weiss.

   Juergen Schoenwaelder, Dave Perkins, Frank Strauss, Harrie
   Hazewinkel, and Bert Wijnen are especially to be noted for review
   comments on the structure and usage of the MIB for network management
   purposes, and its compliance with SMIv2.

8.  Security Considerations

   It is clear that this MIB is potentially useful for configuration.
   Anything that can be configured can be misconfigured, with
   potentially disastrous effects.

   At this writing, no security holes have been identified beyond those
   that SNMP Security is itself intended to address.  These relate
   primarily to controlled access to sensitive information and the
   ability to configure a device - or which might result from operator
   error, which is beyond the scope of any security architecture.

   There are many read-write and read-create management objects defined
   in this MIB.  Such objects are often sensitive or vulnerable in some
   network environments.  The support for SET operations in a non-secure
   environment without proper protection can have a negative effect on
   network operations.  The use of SNMP Version 3 is recommended over
   prior versions for configuration control as its security model is
   improved.

   There are a number of managed objects in this MIB that may contain
   information that may be sensitive from a business perspective, in
   that they may represent a customer's service contract or the filters
   that the service provider chooses to apply to a customer's ingress or
   egress traffic.  There are no objects which are sensitive in their
   own right, such as passwords or monetary amounts.

   It may be important to even control GET access to these objects and
   possibly to even encrypt the values of these objects when sending
   them over the network via SNMP.  Not all versions of SNMP provide
   features for such a secure environment.

   SNMPv1 by itself is not a secure environment.  Even if the network
   itself is secure (for example by using IPSec), even then, there is no
   control as to who on the secure network is allowed to access and
   GET/SET (read/change/create/delete) the objects in this MIB.

   It is recommended that the implementors consider the security
   features as provided by the SNMPv3 framework.  Specifically, the use
   of the User-based Security Model [RFC 2574] and the View-based Access
   Control Model [RFC 2575] is recommended.

   It is then a customer/user responsibility to ensure that the SNMP
   entity giving access to an instance of this MIB, is properly
   configured to give access to the objects only to those principals
   (users) that have legitimate rights to indeed GET or SET
   (change/create/delete) them.

9. Intellectual Property Rights

   The IETF takes no position regarding the validity or scope of any
   intellectual property or other rights that might be claimed to
   pertain to the implementation or use of the technology described in
   this document or the extent to which any license under such rights
   might or might not be available; neither does it represent that it
   has made any effort to identify any such rights.  Information on the
   IETF's procedures with respect to rights in standards-track and
   standards-related documentation can be found in BCP-11.  Copies of
   claims of rights made available for publication and any assurances of
   licenses to be made available, or the result of an attempt made to
   obtain a general license or permission for the use of such
   proprietary rights by implementors or users of this specification can
   be obtained from the IETF Secretariat.

   The IETF invites any interested party to bring to its attention any
   copyrights, patents or patent applications, or other proprietary
   rights which may cover technology that may be required to practice
   this standard.  Please address the information to the IETF Executive
   Director.
