Drawbacks of the Internet Undesirable Material Security Finding Information Filtering
3
Undesirable Information There is little control over what is on the web. As many of you know it is extremely easy to publish material onto the world wide web. On the web a vast amount of the material is either: offensive misleading unreliable or plain rubbish Surfers must exercise judgement when deciding which sites and what information is reliable.

Undesirable Information Availability Undesirable information is available as it has always been but now it is easier to get hold of. Pornography It is very easy to find and can be obtained anonymously or even by mistake. People who would not dream of buying from a shop can obtain it from home. Criminal Activities Groups can co-ordinate their activities. This can be positive but it does allow criminal gangs to operate e.g. violent crime like football violence Terrorists Terrorists have been able to obtain information about how to procure and produce weapons. They are also able to exchange information. Racism and Hatred Material promoting distrust or hatred towards certain groups is easy to find and distribute. The views can easily be published no matter how unbalanced. Laws Every country has different laws. This means that information may be legal in one country but not in another. It is becoming impossible to police.

Security Data can travel by any route to a destination which means it could be intercepted and read. With this in mind many people are wary about using credit cards on line and sending sensitive information via email. Encryption techniques are used to try to prevent unauthorised access to information. Access can be gained to your machine from elsewhere on the internet. To try to prevent this firewalls are initiated.
6
Finding and Searching Due to the amount of information it is difficult to find what you want. Search engines all work in different ways, some look for headings, others look inside the web sites and others only search other search engines. Questions must be phrased carefully. Following links from trusted sites can reduce the amount of time wasted in following up searches.
7
Filtering It is not possible to block access to all sites but most people believe children should be protected. Filters can be used to prevent sites showing certain images or information from being viewed. Their success is limited. Distribution of files via the internet is easy and this may lead to breaches of copyright etc.
