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 Remote Authentication Dial-In User Service (RADIUS) [RFC2865] Dynamic Authorization Client (DAC) functions that support the dynamic authorization extensions as defined in RFC 3576.
このメモは、インターネットコミュニティのネットワーク管理プロトコルで使用するための管理情報ベース（MIB）の一部を定義します。特に、RFC 3576で定義されている動的承認拡張機能をサポートする動的認証クライアント（DAC）関数のリモート認証ダイヤルインユーザーサービス（RADIUS）[RFC2865]動的認証クライアント（DAC）関数について説明します。
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. This RADIUS Dynamic Authorization Client MIB complements the managed objects used for managing RADIUS authentication and accounting servers, as described in [RFC4669] and [RFC4671], respectively.
[RFC3576]に記載されているように、切断と承認の変更（COA）メッセージを処理するために、ネットワークアクセスサーバー（NAS）デバイスの動的な承認拡張機能をサポートすることがますます重要になっています。その結果、半径の動的認証エンティティの効果的な管理はかなり重要です。[RFC4669]と[RFC4671]でそれぞれ説明されているように、このRADIUS動的認証クライアントMIBは、それぞれRADIUS認証と会計サーバーの管理に使用される管理オブジェクトを補完します。
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 [RFC2119].
「必須」、「そうしない」、「必須」、「shall」、「shall "、" ingle "、" should "、" not "、" becommended "、" bay "、および「optional」は、[RFC2119]に記載されているように解釈される。
Dynamic Authorization Server (DAS)
動的認証サーバー（DAS）
The component that resides on the NAS that processes the Disconnect and Change-of-Authorization (CoA) Request packets [RFC3576] sent by the Dynamic Authorization Client.
Dynamic Authorizationクライアントによって送信された切断と承認の変更（COA）要求パケット[RFC3576]を処理するNASに存在するコンポーネント。
Dynamic Authorization Client (DAC)
ダイナミック認証クライアント（DAC）
The component that sends Disconnect and CoA-Request packets to the Dynamic Authorization Server. Although this component often resides on the RADIUS server, it is also possible for this component to be located on a separate host, such as a Rating Engine.
切断パケットとCoA-Requestパケットを動的認証サーバーに送信するコンポーネント。このコンポーネントはしばしばRADIUSサーバーに存在しますが、このコンポーネントは、評価エンジンなどの別のホストに配置することも可能です。
Dynamic Authorization Server Port
動的認証サーバーポート
The UDP port on which the Dynamic Authorization Server listens for the Disconnect and CoA requests sent by the Dynamic Authorization Client.
Dynamic Authorizationクライアントから送信された切断およびCOAリクエストの動的認証サーバーが耳を傾けるUDPポート。
For a detailed overview of the documents that describe the current Internet-Standard Management Framework, please refer to section 7 of [RFC3410].
現在のインターネット標準管理フレームワークを説明するドキュメントの詳細な概要については、[RFC3410]のセクション7を参照してください。
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].
管理されたオブジェクトは、管理情報ベースまたはMIBと呼ばれる仮想情報ストアからアクセスされます。MIBオブジェクトは通常、単純なネットワーク管理プロトコル（SNMP）からアクセスされます。MIBのオブジェクトは、管理情報の構造（SMI）で定義されたメカニズムを使用して定義されます。このメモは、STD 58、RFC 2578 [RFC2578]、STD 58、RFC 2579 [RFC2579]、およびSTD 58、RFC 2580 [RFC2580]に記載されているSMIV2に準拠したMIBモジュールを指定します。
"Dynamic Authorization Extensions to RADIUS" [RFC3576] defines the operation of Disconnect-Request, Disconnect-ACK, Disconnect-NAK, CoA-Request, CoA-ACK, and CoA-NAK packets. [RFC4673] defines the Dynamic Authorization Server MIB and the relationship with other MIB modules. This MIB module for the Dynamic Authorization Client contains the following:
「Dynamic Authorization Extensions to RADIUS」[RFC3576]は、切断、切断、切断、COA-Request、COA-ACK、およびCOA-NAKパケットの操作を定義します。[RFC4673]は、動的認証サーバーMIBと他のMIBモジュールとの関係を定義します。動的認証クライアントのこのMIBモジュールには、以下が含まれています。
1. Two scalar objects
1. 2つのスカラーオブジェクト
2. One Dynamic Authorization Server table. This table contains one row for each DAS with which the DAC shares a secret.
2. 1つの動的認証サーバーテーブル。このテーブルには、DACが秘密を共有する各DASの1つの行が含まれています。

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.
このMIBモジュールには、読み取りワイトおよび/またはread-Createの最大アクセス句を持つ管理オブジェクトはありません。したがって、このMIBモジュールが正しく実装されている場合、侵入者が直接SNMPセット操作を介してこのMIBモジュールの管理オブジェクトを変更または作成できるリスクはありません。
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: radiusDynAuthServerAddress and radiusDynAuthServerAddressType
このMIBモジュールの読み取り可能なオブジェクトのいくつか（つまり、アクセスできないこと以外に最大アクセスを備えたオブジェクト）は、一部のネットワーク環境で敏感または脆弱と見なされる場合があります。したがって、これらのオブジェクトへのアクセスを取得および/または通知することさえ制御し、SNMPを介してネットワーク上に送信するときにこれらのオブジェクトの値を暗号化することも重要です。これらはテーブルとオブジェクトであり、その感度/脆弱性です：radiusdynauthserveraddressおよびradiusdynauthserveraddresstype

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.
SNMPV3以前のSNMPバージョンには、適切なセキュリティは含まれていませんでした。ネットワーク自体が（たとえばIPSECを使用して）安全である場合でも、それでもセキュアネットワークで誰がアクセスして取得/セット（読み取り/変更/作成/削除/削除）を制御することはできません。MIBモジュール。
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).
実装者は、SNMPV3暗号化メカニズム（認証とプライバシー用）の完全なサポートを含む、SNMPV3フレームワーク（[RFC3410]、セクション8を参照）で提供されるセキュリティ機能を考慮することをお勧めします。
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.
さらに、SNMPV3より前のSNMPバージョンの展開は推奨されません。代わりに、SNMPV3を展開し、暗号化セキュリティを有効にすることをお勧めします。その場合、このMIBモジュールのインスタンスへのアクセスを提供するSNMPエンティティが、実際に取得または設定する正当な権利を持つプリンシパル（ユーザー）にのみオブジェクトにアクセスできるように適切に構成されていることを保証するのは、顧客/オペレーターの責任です（変更を変更します（変更）/作成/削除）それら。
