Now that there are thousands and thousands of people who have possibility to access and create things on the Web, some of all these people may have, and some do have bad intentions and produce things that are not suitable for everybody to read. Even if there exists an informal list of rules, netiquette, that are the dos and don'ts of behaviour when you are connected to the Internet, people do as they want and that can harm all "innocent" people.
How do we make it impossible for inconvenient matters to get on the Web and how to limit people to visit such pages? Is it possible to limit access so that only "goodhearted" people browse the Web? Or is it better to limit every user so that specific person only can access specific pages?
Is there a need for access control? Does someone have to restrict what other people may read and see? Is the world not free for us to think and do what we want? Who is allowed to stand over other people and decide what we are allowed to see and read and what we are denied to see/read?
There are loads of questions and if you continue reading there will be information about different ways to limit access and different types of software and hardware that can control what pages a person may access and not. The main problem about access control is that even if you limit people's accessibility, there are always people who can misuse other people's passwords and you will be able to find opportunities to access even if you are not authorised or not in the state of coping with using the Web.
