26、orial only changes have been incorporated in the document. Introduction The present document is part of a TS-family covering the 3rdGeneration Partnership Project; Technical Specification Group Services and System Aspects; Telecommunication management; as identified below: 32.371: “Security Manageme
27、nt concept and requirements“. 32.372: “Security services for Integration Reference Point (IRP); Information 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 I
28、tf-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 32.101 1 and 3GPP TS 32.102 2. IRP consists of IRPMan
29、ager 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 between IRPManagers and IRPAgents. All the threats are p
30、otential 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. The present document is applicable to the Interface IRP specifications. That is to say, it is only concerned
31、with the security aspects of operations/notifications/file deployed across the Itf-N. ETSI ETSI TS 132 376 V13.0.0 (2016-02)63GPP TS 32.376 version 13.0.0 Release 131 Scope The present document specifies the Solution Set for the IRP whose semantics is specified in 3GPP TS 32.372 5 Security Service f
32、or IRP Information Service. This Solution Set specification is related to 3GPP TS 32.372 V12.0.X 5. Note that 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
33、. 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 provisions of the present document.

43、P TS 32.376 version 13.0.0 Release 13Annex A (normative): CORBA Solution Set This annex contains 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
44、Security Services is specified in 3GPP TS 32.372 5. This clause specifies features that are specific 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 att
45、ached to network management information are transferred between IRPManager and IRPAgent to address Authentication, Authorization, Activity Log and file integrity requirements. IRPManager ApplicationSecurity ServicesTransport layerIRPAgent ApplicationSecurity ServicesTransport layernetwork management
46、informationattached Security AttributesFigure A.1: Principles of IRP Security Services The basic 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 man
47、agement information in a secured manner, the sender Security Service attaches Security Attributes 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 documen
48、t 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
49、define their respective Security Attributes. The Security Attributes used by the Interceptor mechanism and the mechanism itself are defined by 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 IRPManager and IRPAgent. Such mechanism is defined in annex A of 3GPP TS 32.371 4. ETSI
