25、P TS 32.376 version 15.0.0 Release 15Foreword This Technical Specification has been produced by the 3rdGeneration Partnership Project (3GPP). 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 con

26、tents of the present document, it will be 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 d

27、ocument under change control. y the second 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

28、-family covering the 3rdGeneration Partnership 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

29、Service (IS)“. 32.376: “Security services for Integration Reference Point (IRP); Solution Set (SS) definitions“. In 3GPP SA5 context, IRPs are 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 rel

30、ated 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 there are three types of transaction between IRPManager and IRPAgent, which are o

31、peration 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 degradation of telecommunication services, which operators should take measures

32、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 operations/notifications/file deployed across the Itf-N. ETSI ETSI TS 132 376 V

33、15.0.0 (2018-07)63GPP TS 32.376 version 15.0.0 Release 151 Scope The present document specifies the Solution Set 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 V14.0.X 5. Note tha

34、t within the present document there are several alternate solutions. Specific choices will to be 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 f

45、 the CORBA Solution Set for Security Services whose semantics is specified in Security Services for IRP: Information Service (TS 32.372 5). A.1 Architectural features The overall architectural feature of Security Services is specified in 3GPP TS 32.372 5. This clause specifies features that are spec

46、ific to the CORBA Solution. A.1.1 Principles of IRP Security Services As shown in figure A.1, the Security Services are between IRP Application layer and Transport layer. Security Attributes which are attached to network management information are transferred between IRPManager and IRPAgent to addre

47、ss Authentication, Authorization, Activity Log and file integrity requirements. IRPManager ApplicationSecurity ServicesTransport layerIRPAgent ApplicationSecurity ServicesTransport layernetwork managementinformationattached Security AttributesFigure A.1: Principles of IRP Security Services The basic

48、 idea of these Security Services is as follows: Security Services on IRPManager side and Security Services on IRPAgent side cooperate to secure the Itf-N. When IRPManager and IRPAgent exchange network management information in a secured manner, the sender Security Service attaches Security Attribute

49、s to the network management information. The receiver 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 Security 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 Att
