Sorry, but copying text is forbidden on this website!

To prevent companies from using or passing on confidential information to other companies without the permission of the person who the data is about, companies will need to protect the data. With the popularity of the Internet there are opportunities for thieves to steal their personal data. So the government set a law (data protection act) which is used to protect people’s rights concerning how data is used and you also have the right to see such information and have any errors corrected. Also organisation will want to keep data confidential because it will not want its competitors to know how the business is going.

List the 8 principles of the Data Protection Act The Data Protection Act says the personal data should: 1. Be adequate, relevant and not excessive. For example college should keep students details and details must be just what is needed and nothing more. 2. Be processed in accordance with the data subject right. For example the person that the data refers to have the right to read the information about him/her and the organisation should provide hem/her with information they need. 3. Be accurate and be kept up to date. There is a duty to keep it up to date, for example to change an address when people move.

Purpose of assignment In this assignment, I have to do research and get information on the importance of data security and data safety. M research must be from ICT sources and non ICT sources and by using the evidence that I collect I should explain the importance of keeping customer information confidential, the main provision of data protection act, the role of browsers and email in internet communications, the difference between internet, intranet and extranet, the major threats to organization from internet and finally a poster that explains the importance of data safety and data security.

Use of ICT to enforce security entry on doors, and protected areas of buildings i. e. : swipe cards, fingerprint ID, voice recognition. Firewall: This is a security device, which acts as a single entry/exit point for information and access to a computer system. All traffic must pass through the firewall and therefore a system is secure from external threats.

A firewall usually sits between the internal network of an organisation and access by the internet. Virus Protection: It is usual for systems to have some form of anti-virus software installed and running in the background. All files and devices introduced to the system would be scanned, any attempts to alter system files would be blocked, and notification made to the user/system administrator. Preventing the use of floppy disks is a good method of eliminating one source of potential virus problems. Identification of Users: A system of user ID’s and passwords is a simple method of preventing unauthorised personnel accessing the system.

These should be managed by the system administrator. With this, only some users will have access to certain programmes and data therefore increasing the level of security on sensitive data. In addition, some users may only be able to read the data and not write the data. Other users may not have the ability to delete or even to access certain files. Encryption software: the data may be encrypted (coded) into a form, which can only then be decoded by the intended user. If the data falls into the wrong hands, it will be meaningless.

Backups: To guard against the loss of data, backups should be regularly made. These backups should be stored in a separate place, preferably in a fireproof environment. Passwords software: Password protection usually involves a person typing in:  A User Name – to identify the person.  A Password – to identify the person. He should be the only one to know what it is. Computer viruses: which are programs that destroy the way computer operates without the knowledge of the user, there are huge numbers of viruses some are extremely malicious with the ability to delete or damage files and programs.

Some of the threats that they cause to computer systems include:  Deleting data on the hard disk of the organisation computer system.  Enabling hackers to hijack the organisation system and use it for their own purposes. How do viruses spread:  CDs and floppy disks containing infected documents. Emails containing infected attachments. Hackers: who gain unauthorised access to computer systems for the purpose of stealing and corrupting data, also gaining access to financial information about the organisation business or their customers for the purposes of fraud.

Security measures may include… Each user should be given a user name and a password.  Computer usage may be logged.  Computers should be disconnected from a network when not in use.  Use a firewall – a computer running software, which detects hackers dialling in to a network. Spam: authorised users downloading a web page or receiving an email with hidden active content that attacks the organisation system or send sensitive information to unauthorised people. Organisation can stop spreading of spam by using spam filtering software.

Spy ware: is software that is placed on organisation computer when the employee visits certain websites, it is used to secretly gather information about the organisation usage and sends it back to advertiser or other interested company to tracking the organisation system use . it can also slow down or crashes the organisation computer Pop up: Many company advertisers on the Internet by using windows that pop up in the middle of computer screen to display a message. They might also open when you click a link or button on a Web site, and they might open either over or under the window, you wish to view.

Some pop-up windows can contain inappropriate content or can be a way for employee of organisation to accidentally download dangerous software (called spyware or adware) onto organisation computer. Infringement of copyright: Internet users are not allowed to copy or print some internet materials such as; video, music, files and photos without the permission of copyright holder and sometimes they may have to pay a licence to do so. Theft and fraud: credits card fraud for example people can steal the details on credits card and using them illegally to buy goods.

(e. g. electrical repair, picture framing, photography, diving instruction, retail shops, and hotels) Partnership A Partnership can be liable for all debts, it is easy to setup, but is also inexpensive to form.
