Internet-Draft RADIUS Auth Server MIB (IPv6) August 2005 1. Terminology The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [RFC2119]. This document uses terminology from RFC 2865 [RFC2865]. 2. Introduction This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. The objects defined within this memo relate to the Remote Authentication Dial-In User Service (RADIUS) Authentication Server as defined in RFC 2865 [RFC2865]. 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 RFC 3410 [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, RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580 [RFC2580]. 4. Scope of Changes This document updates RFC 2619 [RFC2619], RADIUS Authentication Server MIB, by deprecating the radiusAuthClientTable table and adding a new table, radiusAuthClientExtTable, containing radiusAuthClientInetAddressType and radiusAuthClientInetAddress. The purpose of these added MIB objects is to support version neutral IP addressing formats. The existing table containing radiusAuthClientAddress is deprecated. RFC 4001 [RFC4001], which defines the SMI Textual Conventions for version neutral IP addresses, contains the following recommendation. 'In particular, when revising a MIB module that contains IPv4 Nelson Expires March 3, 2006 [Page 3]
Internet-Draft RADIUS Auth Server MIB (IPv6) August 2005 specific tables, it is suggested to define new tables using the textual conventions defined in this memo [RFC 4001] that support all versions of IP. The status of the new tables SHOULD be "current", whereas the status of the old IP version specific tables SHOULD be changed to "deprecated". The other approach, of having multiple similar tables for different IP versions, is strongly discouraged.' 5. Structure of the MIB Module The structure of the MIB Module defined in this memo corresponds to the structure of the MIB Module defined in RADIUS Authentication Server MIB, RFC 2619 [RFC2619]. This MIB module contains fourteen scalars as well as a single table, the RADIUS Authentication Client Table, which contains one row for each RADIUS authentication client with which the server shares a secret. Each entry in the RADIUS Authentication Client Table includes thirteen columns presenting a view of the activity of the RADIUS authentication server. 6. Deprecated Objects The deprecated table in this MIB is carried forward from RFC 2619 [RFC2619]. There are two conditions under which it MAY be desirable for managed entities to continue to support the deprecated table: 1. The managed entity only supports IPv4 address formats. 2. The managed entity supports both IPv4 and IPv6 address formats, and the deprecated table is supported for backwards compatibility with older management stations. This option SHOULD only be used when the IP addresses in the new table are in IPv4 format and can accurately be represented in both the new table and the deprecated table. Managed entities SHOULD NOT instantiate the deprecated table containing IPv4-only address objects when the RADIUS server address represented in the table row is not an IPv4 address. Managed entities SHOULD NOT return inaccurate values of IP address or SNMP object access errors for IPv4-only address objects in otherwise populated tables. 7. Definitions 4.

IANA Considerations This document requires IANA assignment of a number in the MIB-2 OID number space. 9. Security Considerations There are no management objects defined in this MIB that have a MAX- ACCESS clause of read-write and/or read-create. So, if this MIB is implemented correctly, then there is no risk that an intruder can alter or create any management objects of this MIB via direct SNMP SET operations. There are a number of managed objects in this MIB that may contain sensitive information. These are: radiusAuthClientIPAddress This can be used to determine the address of the RADIUS authentication client with which the server is communicating. This information could be useful in mounting an attack on the authentication client. radiusAuthClientInetAddress This can be used to determine the address of the RADIUS authentication client with which the server is communicating. This information could be useful in mounting an attack on the authentication 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. SNMP versions prior to SNMPv3 do not provide 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 [RFC2574] and the View-based Access Nelson Expires March 3, 2006 [Page 19]
Internet-Draft RADIUS Auth Server MIB (IPv6) August 2005 Control Model [RFC2575] 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. 10.
