Its aim is to make the UK the safest place in the world for childre

17、n to use the Internet and to help protect children across the world from abuse fuelled by criminal misuse of new technologies. The Task Force brings together representatives from law enforcement agencies, child protection organizations, the Internet industry, Government and representatives from oppo

18、sition parties.The Task Forces work to date includes the development of models of good practice for providers of Internet chat, instant messaging, web-based services and search services, guidance on the moderation of interactive services, and is currently developing good practice guidance for provid

19、ers of social networks and user-generated content services. The Task Force also contributed to the development of codes of practice for new forms of content on mobile phones and passive location services and worked on public awareness campaigns and guidance for young people, and their parents and ca

20、rers, for using the Internet and related technologies safely. In addition to the above, the Task Force recommended the creation of the Child Exploitation and Online Protection Centre (CEOP).Recognizing the role of parents and carers in developing a safe Internet environment, a subgroup of the Task F

21、orce was created in 2003 to specifically consider rating, filtering and monitoring products (access control systems) for use in the home.At this time numerous commercial products were emerging, but there were concerns over their quality and effectiveness. Additionally, there was no permanent, indepe

22、ndent source of evaluation for such products, meaning that parents/carers often faced difficulties in understanding the many issues, and in finding reliable products which met their requirements.In 2004, the subgroup coordinated a short-term project to produce a guide for parents on available option

23、s for managing their childrens use of the Internet. Longer-term aims included the development of a solution for keeping parents informed of the risks, and suitable products and services for managing them, which could also keep pace with technological changes. The subgroup decided to develop a third-

24、party conformity certification scheme against which access control systems could be tested, providing impartial advice to parents on product features, capabilities, ease of use and confidence in their quality.This Publicly Available Specification has been developed primarily for use by software deve

25、lopers working with access control systems. It sets out the minimum performance requirements for the access control systems to obtain a third-party conformity certification. An overview of the laboratory procedures is given in Annex A.It must be recognized however, that no access control system can

26、be effective 100% of the time and that, despite rigorous controls, there may still be occasions when inappropriate materials may be accessed. In such instances, providing education on the issues, and developing strategies for protecting themselves, is essential in helping children and young people b

27、ecome safe and discriminating users of Internet-based content and services. Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 11/07/2008 03:21, Uncontrolled Copy, (c) BSIPAS 74:20082 BSI 2008This Publicly Available Specification is primarily aimed at the development of access control systems fo

28、r use in the consumer market in the UK. It covers both those products installed locally (i.e. by a parent/carer on a home computer) and remotely managed products/services (i.e. those products or services offered by Internet Service Providers). The development of this Publicly Available Specification

29、 has been jointly sponsored by the Home Office and Ofcom.1 ScopeThis Publicly Available Specification specifies requirements for products, services, tools and other systems that allow UK adult Internet users to easily control childrens access to inappropriate Internet-based content and services.It s

30、pecifies requirements on: a) ease of installation, configuration and use;b) effectiveness;c) minimum features;d) ease of updating;e) quality of instructions;f) consumer communications and support.By using a certified product or service, parents/carers will have confidence in the ability of the acces

31、s control system to:a) block inappropriate content (see Clause 4);b) block communications via Internet-based services that are inappropriate (see Clause 5);c) prevent unauthorized users from changing or disabling the access control settings (see Clause 6);d) provide an appropriate level of protectio

32、n (as specified by this PAS) upon implementation/installation either through the use of default settings or configuration in accordance with user documentation (see Clause 7);e) configure the product or service where such a capability is offered (see Clause 8);f) remain up to date (within the terms

33、of any licensing or subscription requirements) (see Clause 9).Furthermore, where the access control system can be installed, parents/carers will have confidence in their ability to uninstall/remove the product or service (see Clause 10).Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 11/07/20

34、08 03:21, Uncontrolled Copy, (c) BSI BSI 2008 3PAS 74:2008By using a certified product or service, parents/carers will:a) have confidence in the ability to obtain suitable system support should they encounter problems with implementing, maintaining or installing/removing the access control system (s

35、ee Clause 11);b) have confidence in the level and quality of information they will receive in the product description and user documentation provided with the product or service and will have confidence in the quality of the instructions to enable them to effectively install and configure the access

36、 control system to an effective level of protection (see Clause 12);c) have access to user education materials providing information and links to information that enable parents/carers and children to stay informed of the issues and risks of using the Internet (see Clause 13).2 Terms and definitions
