23、IEC 27033-6:2016(E) Introduction In todays world, the majority of both commercial and government organizations have their information systems connected by networks with the network connections being one or more of the following: within the organization; between different organizations; between the o

24、rganization and the general public. Further, with the rapid developments in publicly available network technology (in particular with the Internet) offering significant business opportunities, organizations are increasingly conducting electronic business on a global scale and providing online public

25、 services. The opportunities include the provision of lower cost data communications, using the Internet simply as a global connection medium, through to more sophisticated services provided by Internet service providers (ISPs). This can mean the use of relatively low cost local attachment points at

26、 each end of a circuit to full scale online electronic trading and service delivery systems, using web-based applications and services. Additionally, the new technology (including the integration of data, voice and video) increases the opportunities for remote working (also known as “teleworking” or

27、 “telecommuting”) that enable personnel to operate away from their homework base for significant periods of time. They are able to keep in contact through the use of remote facilities to access organization and community networks and related business support information and services. However, while

28、this environment does facilitate significant business benefits, there are new security risks to be managed. With organizations relying heavily on the use of information and associated networks to conduct their business, the loss of confidentiality, integrity, and availability of information and serv

29、ices could have significant adverse impacts on business operations. Thus, there is a major requirement to properly protect networks and their related information systems and information. In other words, implementing and maintaining adequate network security is absolutely critical to the success of a

30、ny organizations business operations. In this context, the telecommunications and information technology industries are seeking cost- effective comprehensive security solutions, aimed at protecting networks against malicious attacks and inadvertent incorrect actions, and meeting the business require

31、ments for confidentiality, integrity, and availability of information and services. Securing a network is also essential for maintaining the accuracy of billing or usage information, as appropriate. Security capabilities in products are crucial to overall network security (including applications and

32、 services). However, as more products are combined to provide total solutions, the interoperability, or the lack thereof, will define the success of the solution. Security should not only be a thread of concern for each product or service, but should be developed in a manner that promotes the interw

33、eaving of security capabilities in the overall security solution. The purpose of ISO/IEC 27033 is to provide detailed guidance on the security aspects of the management, operation and use of information system networks, and their inter-connections. Those individuals within an organization that are r

34、esponsible for information security in general, and network security in particular, should be able to adapt the material in this document to meet their specific requirements. Its main objectives are as follows. ISO/IEC 27033-1 aims to define and describe the concepts associated with, and provide man

35、agement guidance on, network security. This includes the provision of an overview of network security and related definitions, and guidance on how to identify and analyze network security risks and then define network security requirements. It also introduces how to achieve good quality technical se

36、curity architectures, and the risk, design and control aspects associated with typical network scenarios and network technology areas (which are dealt with in detail in subsequent parts of ISO/IEC 27033). ISO/IEC 27033-2 aims to define how organizations should achieve quality network technical secur

37、ity architectures, designs and implementations that will ensure network security appropriate to their vi ISO/IEC 2016 All rights reservedBS ISO/IEC 27033-6:2016ISO/IEC 27033-6:2016(E) business environments, using a consistent approach to the planning, design and implementation of network security, a

38、s relevant, aided by the use of models/frameworks (in this context, a model/framework is used to outline a representation or description showing the structure and high level workings of a type of technical security architecture/design), and is relevant to all personnel who are involved in the planni

39、ng, design and implementation of the architectural aspects of network security (for example, network architects and designers, network managers, and network security officers). ISO/IEC 27033-3 aims to define the specific risks, design techniques and control issues associated with typical network sce

40、narios. It is relevant to all personnel who are involved in the planning, design and implementation of the architectural aspects of network security (for example, network architects and designers, network managers, and network security officers). ISO/IEC 27033-4 aims to define the specific risks, de

41、sign techniques and control issues for securing information flows between networks using security gateways. It is relevant to all personnel who are involved in the detailed planning, design and implementation of security gateways (for example, network architects and designers, network managers, and

42、network security officers). ISO/IEC 27033-5 aims to define the specific risks, design techniques and control issues for securing connections that are established using virtual private networks (VPNs). It is relevant to all personnel who are involved in the detailed planning, design and implementatio

43、n of VPN security (for example, network architects and designers, network managers, and network security officers). ISO/IEC 27033-6 aims to define the specific risks, design techniques and control issues for securing IP wireless networks. It is relevant to all personnel who are involved in the detai

44、led planning, design and implementation of security for wireless networks (for example, network architects and designers, network managers, and network security officers). It is emphasized that ISO/IEC 27033 provides further detailed implementation guidance on the network security controls that are

45、described at a basic standardized level in ISO/IEC 27002. It should be noted that this part of ISO/IEC 27033 is not a reference or normative document for regulatory and legislative security requirements. Although it emphasizes the importance of these influences, it cannot state them specifically, si

46、nce they are dependent on the country, the type of business, etc. Unless otherwise stated, throughout this part of ISO/IEC 27033, the guidance referenced is applicable to current and/or planned networks, but will only be referenced as “networks” or “the network”.
