19、9:2001(E)vForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISOmember bodies). The work of preparing International Standards is normally carried out through ISO technicalcommittees. Each member body interested in a subject for wh

20、ich a technical committee has been established hasthe right to be represented on that committee. International organizations, governmental and non-governmental, inliaison with ISO, also take part in the work. ISO collaborates closely with the International ElectrotechnicalCommission (IEC) on all mat

21、ters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.Publication as an International Standard

22、requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possibility that some of the elements of this International Standard may be the subject ofpatent rights. ISO shall not be held responsible for identifying any or all such patent rights.International Stan

26、rusion. Data encryption is the most effective protection againstsuch intrusions and should be available for security sensitive communications. The encryption protocol shouldprovide for multiple algorithms and the assignment of separate algorithms for different types of data. A criticalelement of the

27、 encryption program is the control of data encyphering and data decyphering keys (a key managementsystem). This system is responsible for key origination, application, recording, assignment and deletion.4.6 Database modelDatabase maintenance and availability are key features of the FMS. Each SITP an

28、d LITP will maintain separatedatabases. Each site will incorporate a DBMS, including replication capability, as part of the SITP or LITP installation.This DBMS should be independent of the core management software. Data modelling embraces the concept thatdata should be structured in a neutral format

29、 separate from the applications software allowing for the exchange ofdata between applications using the same data model.4.7 Database management system (DBMS)4.7.1 GeneralThe database management system supports a data repository that provides for storage of data in digital form andmanagesa) persiste

30、nt storage of data collected by the system,b) data replication on demand, scheduled or event driven,c) integration of information at multiple remote sites,d) open database connectivity,e) query language,f) concurrency/multiple users,g) referential integrity, andh) translators for applicable data mod

31、els.5ISO 15849:2001(E)4.7.2 Database securityThe DBMS should incorporate protection against improper access, improper modification of data (ensure data integrity), and improper denial of access;It should provide for the following features.a) Operational integrity. This addresses the serialization an

32、d isolation properties of transactions. Serializationmeans that the concurrent run of a set of transactions will give identical results as a sequential run of the sameset of transactions.b) Logical integrity of data allowed range.c) Accountability and auditing record of all read or write access to d

33、ata.d) Privacy control of employment, medical records, etc.e) Delimitation control of information transfer between programs.5 Shipboard information technology platform (SITP)5.1 IntroductionThe SITP consists of the software and hardware required to support a distributed computing network based on th

34、eclient/server model. In general, the SITP will be optimized to respond to a single LITP. For cases where the SITP willrespond to multiple shoreside platforms, a hierarchy should be defined. The SITP consists of layers of computerservices and underlying layers of system services, including a NOS and

35、 a DBMS.5.2 The SITP data acquisition serviceThe SITP data acquisition service is responsible for communicating with the various shipboard control systems ordata collection units in order to acquire operating data. The SITP data acquisition is responsible for the orderlyregistration, control, audit

36、and monitoring of SITP-compliant software processes on the server and supportedworkstations for data acquisition. The SITP data acquisition should provide a framework in which custom interfacescan be developed to a variety of control systems and data acquisition units. Data from the control systems

37、should bestored in the SITP database and be available for analysis and diagnostic applications software on the network. Thisdata can also be transmitted to shore-based monitoring services through the communications network usinggateways to provide one-way communications where required for control sy

38、stem isolation. A key objective of theSITP is to facilitate sharing of data among shipboard systems.The SITP data acquisition service allows the shipboard fleet management systems to acquire information fromsensors or databases in protected systems, e.g navigation and control systems. As the protect

39、ed systems are criticalfor the safety of the ship, access to these systems should normally be through a firewall that can guarantee theintegrity of the protected systems. The firewall will normally be considered as part of the protected systems and,hence, need to comply with appropriate class and re

40、gulatory requirements. These requirements are not addressedby this International Standard.It shall be possible to manually input any shipboard information, which is required for the purpose of fleetmanagement, and is not available directly from other systems.6ISO 15849:2001(E)5.3 SITP executive serv

41、ices5.3.1 GeneralThe standard SITP executive services, as indicated in Figure 2, are required in order to provide overall command andcontrol of the SITP. The SITP executive has overall responsibility to monitor the SITP and control the distributedprocesses that operate as platform services. The SITP

42、 executive itself is a series of services, each of which areresponsible for specific tasks. The SITP provides a layer of insulation and control between high and low levelprocesses. It utilizes a set of structured APIs and internal communication channels for message exchange.The following sections de

43、scribe the services that may be provided by the SITP executive. These services are eachresponsible for the orderly registration, control, audit and monitoring of SITP-compliant software processes on theserver and supported workstations for their specific function. All management data recorded throug

44、h an SITPexecutive process is available to any other SITP-compliant process.5.3.2 Process managementProcess management refers to starting, staging, pausing, resuming and stopping a process. An SITP process maybe an SITP internal process, network operating system process, or an SITP-compliant applica

45、tion. The processmanagement interfaces with the SITP-compliant process through the SITP APIs and with the process managementdatabase. Each physical computer within the SITP will have a process management function. All SITP processes areregistered in the process management database that describes the

46、 important attributes of the process. All processmanagement information is available to SITP applications.5.3.3 Messaging managementThe SITP messaging management interfaces with an SITP-compliant process through the SITP API for applicationsto transport data among all registered entities on the SITP

47、 WAN. This will allow applications to send and receivearbitrary data to and from any other SITP application. This includes ship to shore, ship to ship and shore to ship. Themessaging management should allow for orderly classification of communication endpoints. The messagingmanagement will use commu

48、nications facilities as a transport mechanism for inter-application messages. Thecommunication abstraction provided by the messaging management allows for additional transport mechanisms tobe used in the future.Figure 2 SITP architecture7ISO 15849:2001(E)5.3.4 Replication managementThe SITP replication management uses a generalized mechanism that
