7、 Group 4 (2005-2008) under the ITU-T Recommendation A.8 procedure. ii ITU-T Rec. M.3016.1 (04/2005) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a perm

8、anent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establi

9、shes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary stand

10、ards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Reco

11、mmendation may contain certain mandatory provisions (to ensure e.g. interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents ar

12、e used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Int

13、ellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not rece

14、ived notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database. ITU 2005 All rights reserved

M.3016.1 (04/2005) Introduction Telecommunications is a critical infrastructure for global communication and

20、 economy. Appropriate security for the management functions controlling this infrastructure is essential. Many standards for Telecommunication network management security exist. However, compliance is low and implementations are inconsistent across the various telecommunication equipment and softwar

21、e components. This Recommendation identifies the security requirements to allow vendors, agencies, and service providers to implement a secure telecommunication management infrastructure. Although the present set of requirements represents the current understanding of the state of the art, technolog

22、ies will advance and conditions change. To be successful, this Recommendation must evolve as conditions warrant. This Recommendation is intended as a foundation. Service providers may include additional requirements to meet their specific needs over and above those dealt within this Recommendation.

23、This Recommendation is part of the M.3016.x series of ITU-T Recommendations intended to provide guidance and recommendations for securing the management plane of evolving networks: ITU-T Rec.

25、.3016.1 Security for the management plane: Security requirements 1 Scope ITU-T Recs M.3016.1-3 specify a set of requirements, services and mechanisms for the appropriate security of the management functions necessary to support the telecommunication infrastructure. Because different administrations

26、and organizations require varying levels of security support, ITU-T Recs M.3016.1-3 do not specify whether a requirement, service/or mechanism is mandatory or optional. This Recommendation identifies the security requirements for the management plane in Telecommunication management. It focuses speci

27、fically on the security aspect of the management plane for network elements (NE) and management systems (MS), which are part of the Telecommunication infrastructure. This Recommendation is generic in nature and does not identify or address the requirements for a specific Telecommunications Managemen

28、t Network (TMN) interface. The proforma defined in ITU-T Rec. M.3016.4 is provided to assist organizations, administrations and other national/international organizations, specify the mandatory and optional support of the requirements as well as value ranges, values, etc. to help implement their sec

29、urity policies. 1.1 Purpose ITU-T Rec. M.3016.0 identifies a number of objectives, for securing the management network and threats that introduce risks with regard to meeting these objectives. This Recommendation derives the requirements from the objectives against threats and identifies the securit

30、y services that counter them. In defining the services, mechanisms are used based on certain algorithms. The other Recommendations in this series build on the structure set forth in the ITU-T Rec. M.3016.0 overview. It augments the various steps required to secure the management plane. 1.2 Relations

31、hip with X.805 security architecture ITU-T Rec. X.805 defines security architecture for providing end-to-end network security. The X.805 security architecture logically divides a complex set of end-to-end network security-related features into three separate architectural components, namely Security

32、 Dimensions, Security Layers and Security Planes (see Figure 2/X.805). A Security Dimension is a set of security measures designed to address a particular aspect of the network security. ITU-T Rec. X.805 defines three Security Layers: the Infrastructure Security Layer, the Services Security Layer, a

33、nd the Applications Security Layer, which build on one another to provide network-based solutions. A Security Plane is a certain type of network activity protected by Security Dimensions. Three Security Planes are identified in ITU-T Rec. X.805, namely, Management Plane, Control Plane, and End-User

34、Plane. To provide a complete solution, security measures (e.g., access control, authentication) should be applied to each type of network activity (i.e., management plane activity, control plane activity, and end user plane activity) for the network infrastructure, network services, and network appl

35、ications. This Recommendation focuses specifically on the security aspect of the management plane for network elements (NE) and management systems (MS), which are part of the network infrastructure. 1.3 Relationship with E.408 telecommunication networks security requirements ITU-T Rec. E.408 provide

36、s an overview of security requirements and a framework that identifies security threats to telecommunication networks in general (both fixed and mobile; both voice and data) and gives guidance for planning countermeasures that can be taken to mitigate the risks 2 ITU-T Rec. M.3016.1 (04/2005) arisin

37、g from the threats. It is generic in nature and does not identify or address requirements for specific networks. The M.3016.x series identifies the security requirements, services, and mechanisms for the telecommunication network, i.e., the management plane in general in telecommunication management
