2. Introduction
This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in the Internet community.
It is becoming increasingly important to support Dynamic
Authorization extensions on the NAS devices to handle the Disconnect
and CoA messages as described in [RFC3576] . As a result, the
effective management of RADIUS Dynamic Authorization entities is of
considerable importance. It complements the managed objects used for
managing RADIUS authentication and accounting clients as described in
[RFC2618] and [RFC2620], respectively.

3. The Internet-Standard Management Framework
For a detailed overview of the documents that describe the current
Internet-Standard Management Framework, please refer to section 7 of
[RFC3410].
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. MIB objects are generally
accessed through the Simple Network Management Protocol (SNMP).
Objects in the MIB are defined using the mechanisms defined in the
Structure of Management Information (SMI). This memo specifies a MIB
module that is compliant to the SMIv2, which is described in STD 58,
RFC2578 [RFC2578], STD 58, RFC2579 [RFC2579] and STD 58, RFC2580
[RFC2580].

4. Terminology
Dynamic Authorization Server (DAS)
The component that resides on the NAS which processes the Disconnect
and CoA requests sent by the Dynamic Authorization Client as
described in [RFC3576].
Dynamic Authorization Client (DAC)
The component which sends the Disconnect and CoA requests to the
Dynamic Authorization Server as described in [RFC3576].
Dynamic Authorization Server Port
The UDP port on which the Dynamic Authorization server listens for
the Disconnect and CoA requests sent by the Dynamic Authorization
Client.

Internet-Draft RADIUS Dynamic Authorization Server MIB June 2004
5. Overview
The RADIUS dynamic authorization extensions defined in [RFC3576],
distinguishes between the client function and the server function.
In RADIUS dynamic authorization, clients send Disconnect-Requests and
CoA-Requests, and servers reply with Disconnect-Acks, CoA-Acks, and
CoA-NAKs. Typically NAS devices implement the DAS function, and thus
would be expected to implement the RADIUS dynamic authorization
server MIB, while DACs implement the client function, and thus would
be expected to implement the RADIUS dynamic authorization client MIB.
However, it is possible for a RADIUS dynamic authorization entity to
perform both client and server functions. For example, a RADIUS
proxy may act as a DAS to one or more DACs, while simultaneously
acting as a DAC to one or more DASs. In such situations, it is
expected that RADIUS entities combining client and server
functionality will support both the client and server MIBs.
This memo describes the MIB for dynamic authorization servers and
relates to the following document as follows:
[RFC2618] describes the MIB for a RADIUS authentication client.
[RFC2619] describes the MIB for a RADIUS authentication server.
[RFC2620] describes the MIB for a RADIUS accounting client.
[RFC2621] describes the MIB for a RADIUS accounting server.
[DYNCLNT] describes the MIB for a RADIUS dynamic authorization
client.

7. Security Considerations
There are no management objects defined in this MIB module that have
a MAX-ACCESS clause of read-write and/or read-create. So, if this
MIB module is implemented correctly, then there is no risk that an
intruder can alter or create any management objects of this MIB
module via direct SNMP SET operations
Some of the readable objects in this MIB module (i.e., objects with a
MAX-ACCESS other than not-accessible) may be considered sensitive or
vulnerable in some network environments. It is thus important to
control even GET and/or NOTIFY access to these objects and possibly
to even encrypt the values of these objects when sending them over
the network via SNMP. These are the tables and objects and their
sensitivity/vulnerability:
radiusDynAuthClientAddress and radiusDynAuthClientAddressType
This can be used to determine the address of the DAC with which the
DAS is communicating. This information could be useful in mounting
an attack on the DAC.
radiusDynAuthServerIdentifier
This can be used to determine the Identifier of the DAS. This
information could be useful in impersonating the DAS.
The other readable objects are not really considered as being
sensitive or vulnerable. These objects are:
radiusDynAuthServerInvalidClientAddresses,
radiusDynAuthServDisconRequests,
radiusDynAuthServDupDisconRequests,
radiusDynAuthServDisconAcks,
radiusDynAuthServDisconNaks,
radiusDynAuthServDisconUserSessRemoved,
radiusDynAuthServMalformedDisconRequests,
radiusDynAuthServDisconBadAuthenticators,
radiusDynAuthServDisconPacketsDropped,
radiusDynAuthServCoARequests,
radiusDynAuthServDupCoARequests,
radiusDynAuthServCoAAcks,
radiusDynAuthServCoANaks,
radiusDynAuthServCoAUserSessChanged,
radiusDynAuthServMalformedCoARequests,
radiusDynAuthServCoABadAuthenticators,
radiusDynAuthServCoAPacketsDropped, and
radiusDynAuthServUnknownTypes.

SNMP versions prior to SNMPv3 did not include adequate security.
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 module.
It is RECOMMENDED that implementers consider the security features as
provided by the SNMPv3 framework (see [RFC3410], section 8),
including full support for the SNMPv3 cryptographic mechanisms (for
authentication and privacy).
Further, deployment of SNMP versions prior to SNMPv3 is NOT
RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to
enable cryptographic security. It is then a customer/operator
responsibility to ensure that the SNMP entity giving access to an
instance of this MIB module 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.
