Introduction The present document is part of a TS-family covering the 3rdGeneration Partnership Project; Technical Specification Group Services and System Aspects; Telecommunication management

22、; as identified below: 32.371: “Security Management concept and requirements“. 32.372: “Security services for Integration Reference Points (IRP); Information Service (IS)“. 32.376: “Security services for Integration Reference Point (IRP); Solution Set (SS) definitions“. In 3GPP SA5 context, IRPs are

23、 introduced to address process interfaces at the Itf-N interface. The Itf-N interface is built up by a number of Integration Reference Points (IRPs) and a related Name Convention, which realize the functional capabilities over this interface. The basic structure of the IRPs is defined in 3GPP TS 32.

24、101 1 and 3GPP TS 32.102 2. IRP consists of IRPManager and IRPAgent. Usually there are three types of transaction between IRPManager and IRPAgent, which are operation invocation, notification, and file transfer. However, there are different types of intentional threats against the transaction betwee

25、n IRPManagers and IRPAgents. All the threats are potential risks of damage or degradation of telecommunication services, which operators should take measures to reduce or eliminate to secure the telecommunication service, network, and data. By introducing Security Management, the present document de

26、scribes security requirements to relieve the threats between IRPManagers and IRPAgents. As described in 3GPP TS 32.101 1, the architecture of Security Management is divided into two layers: Layer A - Application Layer Layer B - OAM Principles and high level requirements“. 2 3GPP TS 32.102: “Telecomm

27、unication management; Architecture“. 3 ITU-T Recommendation M.3016 (1998): “TMN security overview“. 4 3GPP TS 33.102: “3G Security; Security architecture“. 5 ITU-T Recommendation X.800: “Security architecture for Open Systems Interconnection for CCITT applications“. 6 3GPP TS 32.150: “Telecommunicat

44、 provider domain to securely exchange messages. The Network domain provides the set of security features that enable nodes in the provider domain to securely exchange signalling data, and protect against attacks on the wireline network. This domain covers protection of the network, network elements

45、and all internal (control and signalling) traffic against security threats. The network elements can belong to a single operator (intra-operator) or to different operators (inter-operator). The OAM - Installation of security mechanisms; - Key management (management part); - Establishment of identiti

46、es, keys, access control information, etc.; - Management of security audit trail and security alarms. Using the above partitioned view, the scope of the present document is focused on security requirements of the OAM - Data integrity; - Accountability; - Availability; 4.3 Security threats A security

47、 threat is defined by ITU-T Recommendation M.3016 3 as a potential violation of security that can be directed at one of the four basic security objectives (see subclause 4.2). ITU-T Recommendation X.800 5 defines the following security threats: - Masquerade. - Eavesdropping. - Unauthorized access. -

48、 Loss or corruption of information. - Repudiation. - Forgery. - Denial of service. NOTE: In contemporary network security jargon, “denial of service“ is most often used to describe a class of attacks that are intended to subvert the delivery of service. In this context the “denial of service“ threat

49、 can be best described as “denial of service delivery“. 4.4 Security Mechanisms and services ITU-T Recommendation X.800 5 defines a set of security mechanisms that can be used to implement security objectives within a network Security mechanisms are manifested within and/or by security services. The fundamental security services are identified by ITU-T Recommendation X.800 5 as being: - Peer entity authentication.
