Conclusion
Tools such as Squid are popular with many company managers. By caching images and files on a server shared by all, Internet bandwidth charges can be reduced.
Squid's password authentication feature is well liked because it allows only authorized users to access the Internet as a means of reducing usage fees and distractions in the office. Unfortunately, an Internet access password is usually not viewed as a major security concern by most users who are often willing to share it with their colleagues. Although it is beyond the scope of this book, you should consider automatically tying the Squid password to the user's regular login password. This will make them think twice about giving their passwords away. Internet access is one thing, letting your friends have full access to your e-mail and computer files is quite another.
