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. This RADIUS Dynamic Authorization Server (DAS) MIB complements the managed objects used for managing RADIUS authentication and accounting clients as described in [RFC4668] and [RFC4670], respectively.
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。[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）デバイスの動的な認証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。このRADIUS Dynamic Authorization Server（DAS）MIBは、それぞれ[RFC4668]および[RFC4670]で説明されているように、RADIUS認証と会計クライアント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 it 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、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].

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を介してアクセスされます。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. Typically, NAS devices implement the DAS function, and thus would be expected to implement the RADIUS Dynamic Authorization Server MIB, whereas DACs implement the client function and thus would be expected to implement the RADIUS Dynamic Authorization Client MIB.
「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。通常、NASデバイスはDAS関数を実装するため、DACSがクライアント機能を実装するのに対し、RADIUS動的認証サーバーMIBを実装するため、RADIUS動的認証クライアントMIBを実装することが期待されます。
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.
ただし、RADIUSの動的認証エンティティがクライアント機能とサーバー機能の両方を実行することが可能です。たとえば、RADIUSプロキシは、1つ以上のDACのDASとして機能し、同時にDACとして1つ以上のDASSとして機能します。このような状況では、クライアントとサーバーの機能を組み合わせたRADIUSエンティティがクライアントとサーバーMIBの両方をサポートすることが期待されています。
This memo describes the MIB for Dynamic Authorization Servers and relates to the following documents as follows:
このメモは、動的認証サーバーのMIBについて説明し、次のドキュメントに関連しています。
[RFC4668] describes the MIB for a RADIUS Auth Client MIB.
[RFC4668]は、半径認証クライアントMIBのMIBを説明しています。
[RFC4669] describes the MIB for a RADIUS Auth Server MIB.
[RFC4669]は、RADIUS AUTH SERVER MIBのMIBを説明しています。
[RFC4670] describes the MIB for a RADIUS Acct Client MIB.
[RFC4670]は、半径ACCTクライアントMIBのMIBを説明しています。
[RFC4671] describes the MIB for a RADIUS Acct Server MIB.
[RFC4671]は、半径ACCTサーバーMIBのMIBを説明しています。
[RFC4672] describes the MIB for a RADIUS Dynamic Auth Client.
[RFC4672]は、半径動的認証クライアントのMIBを説明しています。
A NAS typically implements the MIBs for a RADIUS Authentication Client, a RADIUS accounting client, and a RADIUS Dynamic Authorization Server. However, any one MIB can be implemented without implementing any of the other MIBs; i.e., the MIBs have no dependencies on each other. A typical case would be for a device to implement the MIBs RADIUS authentication server, RADIUS accounting server, and RADIUS Dynamic Authorization Client. A RADIUS proxy might implement any, all, or a subset of the MIBs listed above and the MIB as defined in this document.
NASは通常、RADIUS認証クライアント、RADIUSアカウンティングクライアント、およびRADIUS動的認証サーバーのMIBSを実装します。ただし、他のMIBを実装せずに1つのMIBを実装できます。つまり、MIBSには互いに依存関係がありません。典型的なケースは、デバイスがMIBS RADIUS認証サーバー、RADIUSアカウンティングサーバー、RADIUS動的認証クライアントを実装することです。RADIUSプロキシは、上記のMIBSのサブセット、およびこのドキュメントで定義されているMIBのサブセットを実装する場合があります。

END5. Security Considerations
終了5。セキュリティ上の考慮事項
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:
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。

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.
これらは、DASが通信しているDACのアドレスを決定するために使用できます。この情報は、DACへの攻撃の取り付けに役立つ可能性があります。
radiusDynAuthServerIdentifier
radiusdynauthserveridentifier
This can be used to determine the Identifier of the DAS. This information could be useful in impersonating the DAS.
これは、DASの識別子を決定するために使用できます。この情報は、DASになりすましに役立つ可能性があります。
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。
