Abstract
This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in the Internet community.
In particular, it describes the RADIUS dynamic authorization server
(DAS) functions that support the dynamic authorization extensions as
defined in RFC 3576.

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 network access server (NAS) devices
to handle the Disconnect and Change-of-Authorization (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.

Internet-Draft Dynamic Authorization Server MIB July 2005
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].

Internet-Draft Dynamic Authorization Server MIB July 2005
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]. This is
typically a RADIUS Server, but is not limited to it and may, for
example, be a Rating Engine used for Prepaid Billing.
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 Dynamic Authorization Server MIB July 2005
5. Overview
The RADIUS dynamic authorization extensions defined in [RFC3576],
distinguish 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 documents 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.
A NAS typically implements the MIBs for a RADIUS authentication
client, a RADIUS accounting client, and a RADIUS dynamic
authorization server. However, there is not strict relationship
between these three MIBs, i.e. one MIB can be implemented without
implementing the other MIBs. Similarly, for the other 3 MIBs
mentioned above, a typical case would be where the MIBs for a RADIUS
authentication server, a RADIUS accounting server, and a RADIUS
dynamic authorization client are implemented by the same device.
However, also for these 3 MIBs, they can be implemented independent
from each other. A RADIUS proxy might implement any of these 6 MIBs,
but can also implement any subset of these MIBs.

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
These 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:
radiusDynAuthServerDisconInvalidClientAddresses,
radiusDynAuthServerCoAInvalidClientAddresses,
radiusDynAuthServDisconRequests,
radiusDynAuthServDupDisconRequests,
radiusDynAuthServDisconAcks,
radiusDynAuthServDisconNaks,
radiusDynAuthServDisconUserSessRemoved,
radiusDynAuthServMalformedDisconRequests,
radiusDynAuthServDisconBadAuthenticators,
radiusDynAuthServDisconPacketsDropped,
radiusDynAuthServCoARequests,
radiusDynAuthServDupCoARequests,
radiusDynAuthServCoAAcks,
radiusDynAuthServCoANaks,
radiusDynAuthServCoAUserSessChanged,
radiusDynAuthServMalformedCoARequests,
radiusDynAuthServCoABadAuthenticators,
radiusDynAuthServCoAPacketsDropped, and

Internet-Draft Dynamic Authorization Server MIB July 2005
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.
