15、mplications of current legislation for decision makingThe Data Protection Act1998 Data Protection Act (DPA) is the act of the United Kingdom Parliament on the right of the United Kingdom of Great Britain and Northern Ireland to define the identity of the United Kingdom of law on the identity of the
16、living person data processing. In Britain, it is the main regulations for the protection of personal data. Although the bill itself does not mention the privacy, it is through the British law into the EU data protection directive 1995, the Directive requires Member States to protect the basic rights
17、 and freedoms, in particular their privacy, personal data processing.The billwill be the United Kingdoms law is defined as theidentification of biological data processing. Government procurement and personal or corporate information, must comply with the laws and procedures of data protection, and t
18、o minimize duplication of collection. Data protection law requires that Member States to protect the basic rights and freedoms of the people, in particular the right to privacy of personal data processing. In order to ensure the legitimacy of the collected information, the purpose and the scientific
19、 process of collecting legitimacy is collected.Example, Crown Catering Services company should use this behavior.It can better protect the enterprise data and information, reduce enterprise risk. For example, the establishment of the companydatabase. Different levels of staff through different infor
20、mation to obtain data, thus facilitating the data content of the correctness, data integrity and accuracy.Computer Misuse ActThe Computer Misuse Act 1990 is an Act of the Parliament of the United Kingdom,The Act has nonetheless become a model from which several other countries, including Canada and
21、the Republic of Ireland, have drawn inspiration when subsequently drafting their own information security laws.The Act introduced three criminal offences:Unauthorised access to computer access with intent to commit or facilitate commission of further modification of computer material.Example, Crown
22、Catering Services company should use the Computer Misuse Act. Companies must take adequate security measures to prevent unauthorized access. For example, the company can train the staff of the management, and set a password for the computer. It can help companies to better protect and develop their
23、own security.4.0 data communication systemsA local area network (LAN) is a computer network that interconnects computers within a limited area such as a home, school, computer laboratory, or office building, using network media. The defining characteristics of LANs, in contrast to wide area networks
24、 (WANs), include their smaller geographic area, and non-inclusion of leased telecommunication lines.A wide area network (WAN) is a network that covers a broad area ., any telecommunications network that links across metropolitan, regional, national or international boundaries) using leased telecommu
25、nication lines. (Ban Wei, 2002 year) Business and government entities utilize WANs to relay data amongemployees, clients, buyers, and suppliers from various geographical locations. In essence, this modeof telecommunication allows a business to effectively carry out its daily function regardless of l
26、ocation. The Internet can be considered a WAN as well, and is used by businesses, governments, organizations, and individuals for almost any purpose imaginable.The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite(TCP/IP) to link several bi
27、llion devices worldwide. It is an international network of networks that consists of millions of private, public, academic, business, and government packet switched networks, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries an extensive range
28、 of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW),the infrastructure to support email, and peer-to-peer networks for file sharing and telephony.The local area network is a limited distance within the network usually with
29、in a geographic location. Wide area network is a large-scale network, which can be controlled and shared resources. It is bigger thana local area network. Internet is global, the most extensive. It can obtain a large amount of informationresources, to understand the market demandsurvey. Three data c
30、ommunication system has its own advantages, so it should be combined with each other, the development of enterprises will be better.5.0 Benefits of data communication systemsLocal Area NetworkThrough the sharing of software and hardware, local area network can reduce the cost. Therefore, companies c
31、an share resources, such as printers, to save costs. Secondly, the local area network provides an opportunity to communicate with others, which means that the manager can communicate with the local area network more easily. Third, local area network allows companies to set permissions, so different
32、levels of management can share different information and files.Wide Area NetworkWANis more convenient, when a company needs a long distance communication. Wide area network transmission speed is good, the transmission of large amounts of data. and transmission range is wider .It can help companies s
33、olve the problem of remote communication and management. In addition, the wide area network can save time and money.InternetThe Internet provides a wealth of information resources and services. The Internet can help companies advertise, so as to enhance the companys reputation.6.0 Three ThreatsHacke
34、rsComputer hacker is a computer system which is obtained from the unauthorized access. These hackers enter the system and other reasons to test their computer skills, in some way or cause damage to the system effectiveness. Hackers are usually trying to access access through telecommunications links
35、. Traditionally, hackers have referred to the process of writing code, hackers are skilled computer programmers.Crown Catering Services enterprises should set up different system permissions and install security software. The company may require professional processing system vulnerabilities.VirusCo
36、mputer virus is an artificial program or code segment. But these codes have an unexpected negative impact. It will result in the loss of data, create additional file copy, delete files from hard disk and disable system, and destroy data. Computer viruses are ubiquitous, they are usually downloaded f
37、rom the Internet or via email and they can self replicate.Crowncatering service enterprises to hire network security engineers, and set up a firewall to prevent virus intrusion.Data theftData theft is a mistake and accident caused by human error. This is an increasingly serious phenomenonmainly caus
38、ed by system administrators and office staff access technology such as database servers, and some people can not evaluate their information needs, their emotions will affect performance.Crown catering service enterprises should be rented in the interior of the security and the installation of camera
39、s, so as to better avoid the threat of thieves.7.0 ICT innovationsWi-FiWi-Fi is a wireless local area network technology, which allows the electronic device network, which is mainly used in the MHz (12 cm) and 5 MHz(6 cm) ISM SHFradio frequency band. Onthe one hand, Wi-Fi can help managers and emplo
40、yees to transfer information and decision-making.

42、riber Line) to send or download information. Broadband can be connected through telephone lines, cables, modems, and wireless networks. Broadband can be used for video conferencing, it is necessary to. It can help entire firm to access the Internet faster and more easily. A large number of graphics,
