The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. Should the TSG modify the contents of the present document, it will be

21、 re-released by the TSG with an identifying change of release date and an increase in version number as follows: Version x.y.z where:x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 or greater indicates TSG approved document under change control. y the second

22、 digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the document. Introduction The present document is part of a TS-family covering the 3rdGeneration Partner

23、ship Project; Technical Specification Group Services and System Aspects; Telecommunication management; as identified below: 32.371: “Security Management concept and requirements“. 32.372: “Security services for Integration Reference Point (IRP); Information Service (IS)“. 32.373: “Security services

24、for Integration Reference Point (IRP); Common Object Request Broker Architecture (CORBA) solution“. 32.375 “Security services for Integration Reference Point (IRP); File integrity solution“. In 3GPP SA5 context, IRPs are introduced to address process interfaces at the Itf-N interface. The Itf-N inte

25、rface 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 32.101 1 and 3GPP TS 32.102 2. IRP consists of IRPManager and IRPAgent. Usually the

26、re 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 between IRPManagers and IRPAgents. All the threats are potential risks of damage or de

27、gradation of telecommunication services, which operators should take measures to reduce or eliminate to secure the telecommunication service, network, and data. The present document is applicable to the Interface IRP specifications. That is to say, it is only concerned with the security aspects of o

28、perations/notifications/file deployed across the Itf-N. The present document introduces security mechanisms in CORBA context to address IRP security requirements defined in 3GPP TS 32.371 4. ETSI ETSI TS 132 373 V9.0.0 (2010-02)63GPP TS 32.373 version 9.0.0 Release 91 Scope The present document spec

29、ifies the CORBA Solution for the IRP whose semantics is specified in 3GPP TS 32.372 5 Security Service for IRP Information Service. This Solution Set specification is related to 3GPP TS 32.372 5. Note that within the present document there are several alternate solutions. Specific choices will to be

30、 made to counter identified security threats , and to consider performance and cost criteria, i.e. an implementation is not expected to have to support every option for every deployment. 2 References The following documents contain provisions which, through reference in this text, constitute provisi

39、Certificate Authority4 Architectural features The overall architectural feature of Security Services is specified in 3GPP TS 32.372 5. This clause specifies features that are specific to the CORBA Solution. 4.1 Principles of IRP Security Services As shown in figure 4.1, the Security Services are bet

40、ween IRP Application layer and Transport layer. Security Attributes which are attached to network management information are transferred between IRPManager and IRPAgent to address Authentication, Authorization, Activity Log and file integrity requirements. IRPManager ApplicationSecurity ServicesTran

42、 cooperate to secure the Itf-N. ETSI ETSI TS 132 373 V9.0.0 (2010-02)83GPP TS 32.373 version 9.0.0 Release 9When IRPManager and IRPAgent exchange network management information in a secured manner, the sender Security Service attaches Security Attributes to the network management information. The re

43、ceiver analyses the received Security Attributes to determine if the received network management information is authentic and authorized. The present document specifies two alternative CORBA solutions for attaching Security Attributes over Itf-N. They use different CORBA mechanisms to transfer the S

44、ecurity Attributes. One uses The CORBA Request Interceptor while the other uses the CORBA Security Attributes Service (SAS) protocol. Both solutions need to define their respective Security Attributes. The Security Attributes used by the Interceptor mechanism and the mechanism itself are defined by

45、the present document. The ones used by the CORBA SAS protocol are defined in CORBA SAS 7. In addition to the above two alternate mechanisms, the present document also specify a third alternative called Virtual Private Network (VPN) to secure the network management information exchanged between IRPMa

46、nager and IRPAgent. Such mechanism is defined in annex A of 3GPP TS 32.371 4. Table 4.1 identifies the use of the three alternatives to realize the Security Service such as Authentication Security Service, Authorization Security Service, Activity Log Security Service and File Integrity Security Serv

47、ice. Table 4.1: Alternate solutions and Security Service relationship Authentication Security Service Authorization Security Service Activity Log Security Service File Integrity Security Service Request Interceptor solution X X X SAS solution X X X VPN X X NOTE: “X“ means that “The Security Service

48、identified by the column name is realised by the use of Security Attributes in the solution identified by the row name. IRPManager and IRPAgent should decide to use one of the two alternative solutions to provide Authentication, Authorization and Activity Log Security Service at configuration/deploy

49、ment time, and it is not changeable at run time. IRP Manager and IRP Agents should both support VPN. In case CORBA-based security services are used to provide Authentication, Authorization and Activity Log Security Service, IRP Managers shall support SAS Solution and Request Interceptor Solution, while IRP Agents may support either SAS Solution or Request Interceptor Solution (it shall be noted that usage is determined at configuration/deployment time, and it is not changeable at run time). 4.2 Request Interceptor This clause
