But what is a Cookie?

Essentially, a cookie is a small text file placed on a user's computer by a Web site which can log information about the user and the number of visits they make to the site. Web site owners claim that cookies are beneficial to the user, allowing faster access and 'personalization' of the site for that user. However, the use of cookies also raises a number of security issues.

The following guidelines are therefore appropriate:

  • You should be aware that confidential data may be stored by means of a cookie saved on your PC and accessed by a Web site whilst you are browsing - most likely without your knowledge.
  • Alternatively, cookies may be monitored by the use of cookie management software.
  • Ensure that you disable cookies from sites which might potentially share your details with third parties.
  • To turn off automatic cookies, select the security function from your browser toolbar and set "receive cookies" to "off".
  • Where possible, avoid entering confidential data on Web sites or other Internet resources.
