All Internet content carries a risk. Content Filtering helps companies and home users to stop unwanted data. It is used as part of Internet Firewalls or Proxy Servers to screen the content of all incoming Internet traffic. Content filtering usually works by specifying character strings that, if matched, indicate undesirable content that is to be screened out. Content is typically screened for pornographic content and sometimes also for violence- or hate-oriented content.
To be effective you need a database or list of domains and URLs that should be blocked. Building and maintaining your own blacklist would require a huge investment in time. In the first part (Part I) of the workshop we will use a downloaded list which you can later update on the regular bases.
