The Web is much like your own town, where there are good parts of town and bad parts of town. You need to be sure you are comfortable with the section of town you choose to spend time in. Unfortunately, it is harder to judge the quality of an Internet neighborhood because it’s easier to make a seedy site look like a posh neighborhood.
First, consider the level of safety you feel is important for yourself and your family. Understand the potential pitfalls when surfing and interacting with sites, and how to avoid the parts of the Internet you prefer not to encounter. Teach your children the same skills. Then find the tools to help you avoid access to certain types of sites and content.
