6.  Security Considerations

   There are management objects (radiusAccServConfigReset) defined in
   this MIB that have a MAX-ACCESS clause of read-write and/or read-
   create.  Such objects may be considered 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.

   There are a number of managed objects in this MIB that may contain
   sensitive information. These are:

   radiusAccClientAddress
             This can be used to determine the address of the RADIUS
             accounting client with which the server is communicating.
             This information could be useful in impersonating the
             client.

   radiusAccClientID This can be used to determine the client ID for the
             accounting client with which the server is communicating.
             This information could be useful in impersonating the
             client.

   It is thus important to control even GET access to these objects and
   possibly to even encrypt the values of these object 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), 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 implementers consider the security
   features as provided by the SNMPv3 framework. Specifically, the use
   of the User-based Security Model RFC 2574 [12] and the View-based
   Access Control Model RFC 2575 [15] is recommended.  Using these
   security features, customer/users can give access to the objects only
   to those principals (users) that have legitimate rights to GET or SET
   (change/create/delete) them.
