This document updates and clarifies how the rules of [RFC6353] apply when using Transport Layer Security (TLS) or Datagram Transport Layer Security (DTLS) versions later than 1.2. This document jointly refers to these two protocols as "(D)TLS". The update also emphasizes the requirement in [RFC8996] prohibiting the use of TLS versions prior to TLS 1.2 [RFC5246] when using SNMP. Although the text of this document specifically references SNMPv3 and (D)TLS 1.3, this document may be applicable to future versions of these protocols and is backwards compatible with (D)TLS 1.2.
このドキュメントは、輸送層セキュリティ（TLS）またはデータグラムトランスポートレイヤーセキュリティ（DTLS）バージョンを1.2以下に使用する場合の[RFC6353]のルールがどのように適用されるかを更新および明確にします。このドキュメントは、これら2つのプロトコルを「（d）TLS」と共同で言及しています。この更新は、SNMPを使用する場合のTLS 1.2 [RFC5246]の前にTLSバージョンの使用を禁止する[RFC8996]の要件を強調しています。このドキュメントのテキストは、SNMPv3および（d）TLS 1.3を特に参照していますが、このドキュメントはこれらのプロトコルの将来のバージョンに適用できる場合があり、（d）TLS 1.2と互換性があります。
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 RFCs 2578, 2579, and 2580 [STD58].
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、RFCS 2578、2579、および2580 [STD58]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。
Within this document, the terms "TLS", "DTLS", and "(D)TLS" apply to all versions of the indicated protocols. The term "SNMP" means "SNMPv3" unless a specific version number is indicated. Specific version numbers are used when the text needs to emphasize version numbers.
このドキュメント内では、「TLS」、「DTLS」という用語、および「（d）TLS」という用語は、指定されたプロトコルのすべてのバージョンに適用されます。「SNMP」という用語は、特定のバージョン番号が表示されない限り、「SNMPV3」を意味します。テキストがバージョン番号を強調する必要があるときに特定のバージョン番号が使用されます。
For consistency with SNMP-related specifications, this document favors terminology as defined in [STD62], rather than favoring terminology that is consistent with non-SNMP specifications. This is consistent with the IESG decision to not require that the SNMP terminology be modified to match the usage of other non-SNMP specifications when SNMP was advanced to an Internet Standard. "Authentication" in this document typically refers to the English meaning of "serving to prove the authenticity of" the message, not data source authentication or peer identity authentication. The terms "manager" and "agent" are not used in this document because, in the architecture defined in RFC 3411 [STD62], all SNMP entities have the capability of acting as manager, agent, or both, depending on the SNMP application types supported in the implementation. Where distinction is necessary, the application names of command generator, command responder, notification originator, notification receiver, and proxy forwarder are used. See "An Architecture for Describing Simple Network Management Protocol (SNMP) Management Frameworks" (RFC 3411 [STD62]) for further information.
SNMP関連の仕様との一貫性のために、このドキュメントは、非SNMP仕様と一致する用語を支持するのではなく、[STD62]で定義されている用語を好みます。これは、SNMPがインターネット標準に進出したときに他の非SNMP仕様の使用に一致するようにSNMP用語を変更することを要求しないというIESGの決定と一致しています。このドキュメントの「認証」とは、通常、データソース認証やピアアイデンティティ認証ではなく、メッセージの信ity性を証明するために「役立つ」という英語の意味を指します。「マネージャー」と「エージェント」という用語は、このドキュメントでは使用されていません。なぜなら、RFC 3411 [STD62]で定義されているアーキテクチャでは、すべてのSNMPエンティティがSNMPアプリケーションタイプに応じて、マネージャー、エージェント、またはその両方として機能する能力を持っているため実装でサポートされています。区別が必要な場合、コマンドジェネレーターのアプリケーション名、コマンドレスポンダー、通知オリジネーター、通知レシーバー、およびプロキシ転送業者のアプリケーション名が使用されます。詳細については、「単純なネットワーク管理プロトコル（SNMP）管理フレームワークを説明するためのアーキテクチャ」（RFC 3411 [STD62]）を参照してください。
Throughout this document, the terms "client" and "server" are used to refer to the two ends of the TLS transport connection. The client actively opens the TLS connection, and the server passively listens for the incoming TLS connection. An SNMP entity MAY act as a TLS client, TLS server, or both, depending on the SNMP applications supported.
このドキュメント全体で、「クライアント」と「サーバー」という用語を使用して、TLS輸送接続の両端を参照します。クライアントはTLS接続を積極的に開き、サーバーは着信TLS接続のために受動的に耳を傾けます。SNMPエンティティは、サポートされているSNMPアプリケーションに応じて、TLSクライアント、TLSサーバー、またはその両方として機能する場合があります。
Throughout this document, the term "session" is used to refer to a secure association between two instances of the TLS Transport Model (TLSTM) that permits the transmission of one or more SNMP messages within the lifetime of the session. The TLS protocol also has an internal notion of a session, and although these two concepts of a session are related, when the term "session" is used, this document is referring to the TLSTM's specific session and not directly to the TLS protocol's session.
このドキュメント全体を通して、「セッション」という用語は、セッションの寿命内に1つ以上のSNMPメッセージの送信を許可するTLS輸送モデル（TLSTM）の2つのインスタンス間の安全な関連性を参照するために使用されます。TLSプロトコルにはセッションの内部概念もあり、セッションのこれら2つの概念は関連していますが、「セッション」という用語が使用される場合、このドキュメントはTLSTMの特定のセッションを指し、TLSプロトコルのセッションに直接言及していません。
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here.
この文書のキーワード "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", および "OPTIONAL" はBCP 14 [RFC2119] [RFC8174]で説明されているように、すべて大文字の場合にのみ解釈されます。
This document updates [RFC6353]. The changes from [RFC6353] are defined in the following subsections.
このドキュメントは[RFC6353]を更新します。[RFC6353]からの変更は、次のサブセクションで定義されています。
[RFC6353] defines the SnmpTLSFingerprint textual convention to include the one-octet TLS 1.2 hash algorithm identifier. This one-octet algorithm identifier is only applicable to (D)TLS protocol versions prior to 1.3. The TLS community does not plan to ever add additional values to the "TLS HashAlgorithm" registry [RFC5246], because some might incorrectly infer that using a new hash algorithm with TLS 1.2 would overcome the limitations of TLS 1.2. However, there is still a need within TLSTM to support new values as they are developed.
[RFC6353]は、SNMPTLSFINGERPRINTのテキスト条約を定義して、ONCTET TLS 1.2ハッシュアルゴリズム識別子を含む。このワンオクテットアルゴリズム識別子は、1.3より前に（d）TLSプロトコルバージョンにのみ適用できます。TLSコミュニティは、TLS 1.2を使用して新しいハッシュアルゴリズムを使用するとTLS 1.2の制限を克服することを誤って推測する可能性があるため、「TLS Hashalgorithm」レジストリ[RFC5246]に追加の値を追加する予定はありません。ただし、TLSTM内では、開発中に新しい値をサポートする必要があります。
This document updates the definition of SnmpTLSFingerprint to clarify that the one-octet algorithm identifier uses the values in the IANA "SNMP-TLSTM HashAlgorithms" registry; this registry is consistent with the IANA "TLS HashAlgorithm" registry for its initial values but can be extended as needed to support new hashing algorithms without implying that the new values can be used by TLS version 1.2. This change allows the reuse of the existing fingerprint textual convention and minimizes the impact to [RFC6353].
このドキュメントは、snmptlsfingerprintの定義を更新して、One-octetアルゴリズム識別子がiana "snmp-tlstmハッシュハルゴリズム"レジストリの値を使用していることを明確にします。このレジストリは、初期値のIANA「TLSハッシュハルゴリズム」レジストリと一致していますが、新しい値をTLSバージョン1.2で使用できることを暗示することなく、新しいハッシュアルゴリズムをサポートするために必要に応じて拡張できます。この変更により、既存の指紋テキスト条約の再利用が可能になり、[RFC6353]への影響が最小限に抑えられます。
A "Y" in the "Recommended" column (Table 1) indicates that the registered value has been recommended through a formal Standards Action [RFC8126]. Not all parameters defined in Standards Track documents are necessarily marked as "Recommended".
「推奨される」列（表1）の「Y」は、正式な標準訴訟[RFC8126]を通じて登録値が推奨されていることを示しています。標準トラックドキュメントで定義されているすべてのパラメーターが必ずしも「推奨」としてマークされているわけではありません。
An "N" in the "Recommended" column does not necessarily mean that the value is flawed; rather, it indicates that the item either has not been through the IETF consensus process, has limited applicability, or is intended only for specific use cases.
「推奨される」列の「n」は、必ずしも値に欠陥があることを意味するわけではありません。むしろ、アイテムがIETFコンセンサスプロセスを通過していないか、適用性が限られているか、特定のユースケースのみを目的としていることを示しています。
The initial values for the "SNMP-TLSTM HashAlgorithms" registry are defined below:
「SNMP-TLSTMハスハルゴリズム」レジストリの初期値を以下に定義します。

Values 0 through 2 MUST NOT be used by implementations of this document but are listed for historical consistency.
値0〜2は、このドキュメントの実装では使用しないでくださいが、履歴の一貫性のためにリストされています。
The architecture defined in RFC 3411 [STD62] recognizes three levels of security:
RFC 3411 [STD62]で定義されているアーキテクチャは、3つのレベルのセキュリティを認識しています。
* without authentication and without privacy (noAuthNoPriv)
* 認証がなく、プライバシーなし（noauthnopriv）
* with authentication but without privacy (authNoPriv)
* 認証付きが、プライバシーがない（authnopriv）
* with authentication and with privacy (authPriv)
* 認証とプライバシー付き（AuthPRIV）
Cipher suites for (D)TLS 1.3 defined in [RFC8446] provide both authentication and privacy. Cipher suites defined in [RFC9150] for (D)TLS 1.3 provide only authentication, without any privacy protection. Implementations MAY choose to force (D)TLS 1.3 to only allow cipher suites that provide both authentication and privacy.
[RFC8446]で定義されている（d）TLS 1.3の暗号スイートは、認証とプライバシーの両方を提供します。[RFC9150]で（d）TLS 1.3のために定義された暗号スイートは、プライバシー保護なしに認証のみを提供します。実装は、（d）TLS 1.3を強制的に強制することを選択できます。
[RFC6353] states that TLSTM clients and servers MUST NOT request, offer, or use SSL 2.0. [RFC8996] prohibits the use of (D)TLS versions prior to version 1.2. TLSTM MUST only be used with (D)TLS versions 1.2 and later.
[RFC6353]は、TLSTMクライアントとサーバーがSSL 2.0を要求、提供、または使用してはならないと述べています。[RFC8996]は、バージョン1.2より前に（d）TLSバージョンの使用を禁止しています。TLSTMは、（d）TLSバージョン1.2以降でのみ使用する必要があります。
This document specifies additional rules and clarifications for the use of TLS 1.3. These rules may additionally apply to future versions of TLS.
このドキュメントは、TLS 1.3を使用するための追加のルールと説明を指定します。これらのルールは、TLSの将来のバージョンにさらに適用される場合があります。
TLS 1.3 implementations for SNMP MUST NOT enable the 0-RTT mode of session resumption (either sending or accepting) and MUST NOT automatically resend 0-RTT data if it is rejected by the server. 0-RTT is disallowed because there are no "safe" SNMP messages that, if replayed, will be guaranteed to cause no harm at the server side: all incoming notifications or command responses are meant to be acted upon only once. See Section 5 ("Security Considerations") for further details.
SNMPのTLS 1.3実装は、セッション再開の0-RTTモードを有効にしてはならず（送信または受け入れます）、サーバーによって拒否された場合、0-RTTデータを自動的に再送信してはなりません。0-RTTは、再生された場合、サーバー側に害を及ぼさないように保証される「安全な」SNMPメッセージがないため、禁止されています。詳細については、セクション5（「セキュリティ上の考慮事項」）を参照してください。
TLSTM clients and servers MUST NOT request, offer, or use the 0-RTT mode of TLS 1.3. [RFC8446] removed the renegotiation supported in TLS 1.2 [RFC5246]; for session resumption, it introduced a zero-RTT (0-RTT) mode, saving a round trip at connection setup at the cost of increased risk of replay attacks (it is possible for servers to guard against this attack by keeping track of all the messages received). [RFC8446] requires that a profile be written for any application that wants to use 0-RTT, specifying which messages are "safe to use" with this mode. Within SNMP, there are no messages that are "safe to use" with this mode.
TLSTMクライアントとサーバーは、TLS 1.3の0-RTTモードを要求、提供、または使用してはなりません。[RFC8446]は、TLS 1.2 [RFC5246]でサポートされている再交渉を除去しました。セッションの再開のために、ゼロRTT（0-RTT）モードを導入し、リプレイ攻撃のリスクを高めるコストで接続セットアップで往復を節約しました（すべてのすべてを追跡することにより、サーバーがこの攻撃を防ぐことができます受信したメッセージ）。[RFC8446]は、0-RTTを使用したいアプリケーションに対してプロファイルを記述する必要があり、このモードで「安全に使用できる」メッセージを指定します。SNMP内には、このモードで「安全に使用できる」メッセージはありません。
Renegotiation of sessions is not supported, as it is not supported by TLS 1.3. If a future version of TLS supports renegotiation, this RFC should be updated to indicate whether there are any additional requirements related to its use.
セッションの再交渉はサポートされていません。これは、TLS 1.3でサポートされていないためです。TLSの将来のバージョンが再交渉をサポートする場合、このRFCを更新して、その使用に関連する追加要件があるかどうかを示す必要があります。
Section 9 of [RFC8446] requires that, in the absence of application profiles, certain cipher suites, TLS extensions, and TLS protocol invariants be mandatory to implement. This document does not specify an application profile; hence, all the compliance requirements in [RFC8446] apply.
[RFC8446]のセクション9では、アプリケーションプロファイルがない場合、特定の暗号スイート、TLS拡張機能、およびTLSプロトコル不変剤を実装することが必須である必要があります。このドキュメントでは、アプリケーションプロファイルを指定しません。したがって、[RFC8446]のすべてのコンプライアンス要件が適用されます。
This SNMP-TLS-TM-MIB module imports items from RFCs 2578, 2579, and 2580 [STD58], as well as RFCs 3411 and 3413 [STD62]. It also references [RFC1123], [RFC5246], [RFC5280], [RFC5591], [RFC5890], [RFC5952], [RFC5953], [RFC6353], and RFC 2579 [STD58].

DESCRIPTION
"Represents an IPv4 address, an IPv6 address, or an
ASCII-encoded host name and port number.
An IPv4 address MUST be in dotted decimal format followed
by a colon ':' (ASCII character 0x3A) and a decimal
port number in ASCII.
An IPv6 address MUST be a colon-separated format (as
described in RFC 5952), surrounded by square brackets
('[', ASCII character 0x5B, and ']', ASCII character
0x5D), followed by a colon ':' (ASCII character 0x3A)
and a decimal port number in ASCII.
A host name MUST be in ASCII (as per RFC 1123);
internationalized host names MUST be encoded as A-labels as
specified in RFC 5890. The host name is followed by a
colon ':' (ASCII character 0x3A) and a decimal port
number in ASCII. The name SHOULD be fully qualified
whenever possible.
Values of this textual convention are not guaranteed to be
directly usable as transport-layer addressing information,
potentially requiring additional processing, such as
run-time resolution. As such, applications that write
them MUST be prepared for handling errors if such values
are not supported or cannot be resolved (if resolution
occurs at the time of the management operation).
The DESCRIPTION clause of TransportAddress objects that
may have SnmpTLSAddress values MUST fully describe how
(and when) such names are to be resolved to IP addresses
and vice versa.
This textual convention SHOULD NOT be used directly in
object definitions, since it restricts addresses to a
specific format. However, if it is used, it MAY be used
either on its own or in conjunction with
TransportAddressType or TransportDomain as a pair.
When this textual convention is used as a syntax of an
index object, there may be issues with the limit of 128
sub-identifiers specified in SMIv2 (STD 58). It is
RECOMMENDED that all MIB documents using this textual
convention make explicit any limitations on index
component lengths that management software MUST observe.
This MAY be done by either 1) including SIZE constraints
on the index components or 2) specifying applicable
constraints in the conceptual row's DESCRIPTION clause or
in the surrounding documentation."

STATUS current
DESCRIPTION
"A fingerprint value that can be used to uniquely reference
other data of potentially arbitrary length.
An SnmpTLSFingerprint value is composed of a one-octet
hashing algorithm identifier followed by the fingerprint
value. The one-octet identifier value encoded is taken
from the IANA 'SNMP-TLSTM HashAlgorithms' registry. The
remaining octets of the SnmpTLSFingerprint value are
filled using the results of the hashing algorithm.
Historically, the one-octet hashing algorithm identifier
was based on the IANA 'TLS HashAlgorithm' registry
(RFC 5246); however, this registry is no longer in use for
TLS 1.3 and above and is not expected to have any new
registrations added to it. To allow the fingerprint
algorithm to support additional hashing algorithms that

DESCRIPTION
"Maps a subjectAltName's iPAddress to a tmSecurityName by

1) For IPv4, the value is converted into a
decimal-dotted quad address (e.g., '192.0.2.1').
2) For IPv6 addresses, the value is converted into a
32-character all-lowercase hexadecimal string
without any colon separators.
This mapping results in a 1:1 correspondence between
subjectAltName iPAddress values and the tmSecurityName
values.
The resulting length of an encoded IPv6 address is the
maximum length supported by the View-based Access Control
Model (VACM). Using an IPv6 address while the value of
snmpTsmConfigurationUsePrefix is 'true' (see the
SNMP-TSM-MIB, as defined in RFC 5591) will result in
securityName lengths that exceed what the VACM can handle."

MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"This table is used by a (D)TLS server to map the (D)TLS
client's presented X.509 certificate to a tmSecurityName.
On an incoming (D)TLS/SNMP connection, the client's
presented certificate either MUST be validated based on an
established trust anchor or MUST directly match a
fingerprint in this table. This table does not provide
any mechanisms for configuring the trust anchors; the
transfer of any needed trusted certificates for path
validation is expected to occur through an out-of-band
transfer.
Once the certificate has been found acceptable (either via
path validation or by directly matching a fingerprint in
this table), this table is consulted to determine the
appropriate tmSecurityName to identify with the remote
connection. This is done by considering each active row
from this table in prioritized order according to its
snmpTlstmCertToTSNID value. Each row's
snmpTlstmCertToTSNFingerprint value determines whether the
row is a match for the incoming connection:
1) If the row's snmpTlstmCertToTSNFingerprint value
identifies the presented certificate, then consider
the row as a successful match.
2) If the row's snmpTlstmCertToTSNFingerprint value
identifies a locally held copy of a trusted CA
certificate and that CA certificate was used to
validate the path to the presented certificate, then
consider the row as a successful match.
Once a matching row has been found, the
snmpTlstmCertToTSNMapType value can be used to determine
how the tmSecurityName to associate with the session
should be determined. See the 'snmpTlstmCertToTSNMapType'
column's DESCRIPTION clause for details on determining the
tmSecurityName value. If it is impossible to determine a
tmSecurityName from the row's data combined with the data
presented in the certificate, then additional rows MUST be
searched to look for another potential match. If a
resulting tmSecurityName mapped from a given row is not
compatible with the needed requirements of a
tmSecurityName (e.g., the VACM imposes a 32-octet-maximum
length and the certificate-derived securityName could be
longer), then it MUST be considered an invalid match and
additional rows MUST be searched to look for another
potential match.
If no matching and valid row can be found, the connection
MUST be closed and SNMP messages MUST NOT be accepted over
it.
Missing values of snmpTlstmCertToTSNID are acceptable, and
implementations SHOULD continue to the
next-highest-numbered row. It is RECOMMENDED that
administrators skip index values to leave room for the
insertion of future rows (for example, use values of 10
and 20 when creating initial rows).
Users are encouraged to make use of certificates with
subjectAltName fields that can be used as tmSecurityNames.
This allows all child certificates of a single root CA
certificate to include a subjectAltName that maps directly
to a tmSecurityName via a 1:1 transformation. However,
this table is flexible, to allow for situations where
existing deployed certificate infrastructures do not provide
adequate subjectAltName values for use as tmSecurityNames.
Certificates MAY also be mapped to tmSecurityNames using
the CommonName portion of the Subject field. However, the
usage of the CommonName field is deprecated, and thus this
usage is NOT RECOMMENDED. Direct mapping from each
individual certificate fingerprint to a tmSecurityName is
also possible but requires one entry in the table per
tmSecurityName and requires more management operations to
completely configure a device."

DESCRIPTION
"This table is used by a (D)TLS client when a (D)TLS
connection is being set up using an entry in the

snmpTargetAddrTable so that the client can verify that the
correct server has been reached. This verification can
use either 1) a certificate fingerprint or 2) an
identity authenticated via certification path validation.
If there is an active row in this table corresponding to
the entry in the SNMP-TARGET-MIB that was used to
establish the connection and the row's
'snmpTlstmAddrServerFingerprint' column has a non-empty
value, then the server's presented certificate is compared
with the snmpTlstmAddrServerFingerprint value (and the
'snmpTlstmAddrServerIdentity' column is ignored). If the
fingerprint matches, the verification has succeeded. If
the fingerprint does not match, then the connection MUST
be closed.
If the server's presented certificate has passed
certification path validation (RFC 5280) to a configured
trust anchor and an active row exists with a zero-length
snmpTlstmAddrServerFingerprint value, then the
'snmpTlstmAddrServerIdentity' column contains the expected
host name. This expected host name is then compared
against the server's certificate as follows:
- Implementations MUST support matching the expected
host name against a dNSName in the subjectAltName
extension field and MAY support checking the name
against the CommonName portion of the subject
distinguished name.
- The '*' (ASCII 0x2A) wildcard character is allowed in
the dNSName of the subjectAltName extension (and in
CommonName, if used to store the host name), but
only as the leftmost (least significant) DNS label
in that value. This wildcard matches any leftmost
DNS label in the server name. That is, the subject
*.example.com matches the server names a.example.com
and b.example.com but does not match example.com or
a.b.example.com. Implementations MUST support
wildcards in certificates as specified above but MAY
provide a configuration option to disable them.
- If the locally configured name is an
internationalized domain name, conforming
implementations MUST convert it to the ASCII
Compatible Encoding (ACE) format for performing
comparisons, as specified in Section 7 of RFC 5280.
If the expected host name fails these conditions, then the
connection MUST be closed.
If there is no row in this table corresponding to the
entry in the SNMP-TARGET-MIB and the server can be
authorized by another, implementation-dependent means,
then the connection MAY still proceed."

This document updates a transport model that permits SNMP to utilize (D)TLS security services. The security threats and how the TLSTM mitigates these threats are covered throughout this document and in [RFC6353]. Security considerations for TLS are described in Section 10 and Appendix E of TLS 1.3 [RFC8446]. Security considerations for DTLS are described in Section 11 of DTLS 1.3 [RFC9147].
このドキュメントは、SNMPが（d）TLSセキュリティサービスを利用できるようにするトランスポートモデルを更新します。セキュリティの脅威とTLSTMがこれらの脅威をどのように軽減するかは、このドキュメント全体および[RFC6353]でカバーされています。TLSのセキュリティ上の考慮事項は、TLS 1.3 [RFC8446]のセクション10および付録Eで説明されています。DTLのセキュリティ上の考慮事項は、DTLS 1.3 [RFC9147]のセクション11で説明されています。
Implementations should consider the latest recommendations on the use of (DTLS), such as those documented in [RFC9325].
[RFC9325]で文書化されたものなど、実装は（DTL）の使用に関する最新の推奨事項を考慮する必要があります。
SNMP versions prior to SNMPv3 did not include adequate security. Even if the network itself is secure (for example, by using IPsec), 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、セキュアネットワーク上の誰がこのMIBモジュールのオブジェクトにアクセスして取得/セット（読み取り/変更/作成/削除）を許可するかについての制御はありません。
It is RECOMMENDED that only SNMPv3 messages using the Transport Security Model (TSM) or another secure-transport-aware security model be sent over the TLSTM transport.
TLSTMトランスポートを介して送信されるトランスポートセキュリティモデル（TSM）または別の安全な輸送対象セキュリティモデルを使用したSNMPV3メッセージのみをお勧めします。
IANA has created a new registry called "SNMP-TLSTM HashAlgorithms" within the "Structure of Management Information (SMI) Numbers (MIB Module Registrations)" group. The description of this registry is "iso.org.dod.internet.mgmt.mib-2.snmpTlstmMIB.snmpTlstmHashAlgorithms (1.3.6.1.2.1.198.4)".
IANAは、「管理情報の構造（SMI）番号（MIBモジュール登録）」グループ内で「SNMP-TLSTMハスハルゴリズム」と呼ばれる新しいレジストリを作成しました。このレジストリの説明は、「iso.org.dod.internet.mgmt.mib-2.snmptlstmmib.snmptlstmhashalgorithms（1.3.6.1.1.2.1.198.4）」です。
The registry has the following fields: Value, Description, Recommended, and References. The range of values is zero to 255, with initial assignments shown in Section 2.1. The "Recommended" column indicates "Y" for hashing algorithms that are Standards Track and are deemed to be acceptable for widely applicable current use and "N" for hashing algorithms that reflect meanings that are not recommended (e.g., they do not provide sufficient security for modern systems, they are not Standards Track, and they have limited applicability). A blank field indicates that no recommendation is made (e.g., because the value is unassigned or left for private use).
レジストリには、値、説明、推奨、参照の次のフィールドがあります。値の範囲はゼロから255で、セクション2.1に初期割り当てが表示されます。「推奨される」列は、標準の追跡であり、広く適用可能な現在の使用に受け入れられているとみなされるハッシュアルゴリズムの「Y」を示します。最新のシステムの場合、それらは標準の追跡ではなく、適用性が限られています）。空白のフィールドは、推奨が行われていないことを示します（たとえば、値が割り当てられていないか、プライベートな使用のために残されているため）。
This registry is expected to be updated infrequently; as such, its values are limited to one octet.
このレジストリはまれに更新されると予想されます。そのため、その値は1つのオクテットに制限されています。
The policy for updates to the "SNMP-TLSTM HashAlgorithms" registry is Expert Review [RFC8126]. Registry requests should be sent to the <mailto:snmp-tlstm-reg-review@ietf.org> mailing list. Registration requests sent to the mailing list for review SHOULD use an appropriate subject (e.g., 'Request to register value in "SNMP-TLSTM HashAlgorithms" registry'). In addition, designated experts should consult with the <mailto:tls-reg-review@ietf.org> mailing list to make sure that any new hash algorithms are considered for inclusion in this registry.
「SNMP-TLSTMハスハルゴリズム」レジストリの更新に関するポリシーは、専門家レビュー[RFC8126]です。レジストリリクエストは、<mailto：snmp-tlstm-reg-review@ietf.org>メーリングリストに送信する必要があります。レビューのためにメーリングリストに送信された登録リクエストは、適切な科目を使用する必要があります（たとえば、「snmp-tlstm hashalgorithms "レジストリ」に値を登録するリクエスト）。さらに、指定された専門家は、<mailto：tls-reg-review@ietf.org>メーリングリストに相談して、新しいハッシュアルゴリズムがこのレジストリに含めることを考慮していることを確認する必要があります。
Designated experts SHOULD ascertain the existence of suitable documentation that defines a hash algorithm and SHOULD also verify that the request does not conflict with or duplicate other entries in the registry. The experts should also provide a recommendation as to how the "Recommended" column of the registry should be updated. Only publicly available specifications that represent current industry-accepted practices should receive an assignment of "Y" in the "Recommended" column; all other specific assignments in the registry should receive an assignment of "N". Assignments that are nonspecific (e.g., reserved values) SHOULD NOT receive an assigned value for the "Recommended" column.
指定された専門家は、ハッシュアルゴリズムを定義する適切なドキュメントの存在を確認する必要があり、リクエストがレジストリ内の他のエントリと競合または複製しないことも確認する必要があります。また、専門家は、レジストリの「推奨」列をどのように更新するかについての推奨事項も提供する必要があります。現在の業界が受け入れたプラクティスを表す公的に利用可能な仕様のみが、「推奨される」列で「Y」の割り当てを受け取る必要があります。レジストリ内の他のすべての特定の割り当ては、「n」の割り当てを受け取る必要があります。非特異的（予約値など）の割り当ては、「推奨される」列の割り当てられた値を受信しないでください。
Within the three-week review period, the designated experts will either approve or deny the registration request, communicating this decision to the review list and IANA. Denials SHOULD include an explanation and, if applicable, suggestions as to how to make the request successful. Registration requests that are undetermined for a period longer than three weeks can be brought to the IESG's attention (using the <mailto:iesg@ietf.org> mailing list) for resolution.
3週間のレビュー期間内に、指定された専門家は登録要求を承認または拒否し、この決定をレビューリストとIANAに伝えます。拒否には説明を含める必要があります。必要に応じて、リクエストを成功させる方法に関する提案が含まれます。3週間以上未定の登録リクエストは、解決のために（<mailto：iesg@ietf.org>メーリングリストを使用）IESGの注意を引くことができます。
IANA MUST only accept registry updates from the designated experts and SHOULD direct all requests for registration to the review mailing list. While future additions to the "TLS HashAlgorithm" registry (i.e., the registry from which the "SNMP-TLSTM HashAlgorithms" registry was spawned) are not expected, any future additions to the "TLS HashAlgorithm" registry MUST be consistent with the values assigned in the "SNMP-TLSTM HashAlgorithms" registry.
IANAは、指定された専門家からのレジストリの更新のみを受け入れる必要があり、登録のすべての要求をレビューメーリングリストに指示する必要があります。「TLS Hashalgorithm」レジストリ（つまり、「SNMP-TLSTMハスハルゴリズム」レジストリが生成されたレジストリ）への将来の追加は予想されませんが、「TLSハスハルゴリズム」レジストリへの将来の追加は、レジストリが割り当てられた値と一致するものでなければなりません。「SNMP-TLSTMハスハルゴリズム」レジストリ。
It is suggested that multiple designated experts be appointed who are able to represent the perspectives of different applications using this specification, in order to enable broadly informed reviews of registration decisions. In cases where a registration decision could be perceived as creating a conflict of interest for a particular expert, that expert SHOULD defer to the judgment of the other experts.
登録決定の広く情報に基づいたレビューを有効にするために、この仕様を使用してさまざまなアプリケーションの視点を表現できる複数の指定された専門家が任命されることが提案されています。登録決定が特定の専門家に利益相反を生み出すと認識される場合、その専門家は他の専門家の判断に延期すべきです。
