"I want Internet access in my school, but I'm worried about the security of my network"

	Complete firewall security
	A firewall is a computer which joins two networks, but only lets certain types of network message pass from one to the other. In your case, a firewall would join your school's network ("inside" the firewall) to the Internet ("outside" the firewall). The ANT Internet Server Suite makes your server computer act as a firewall. The only network messages allowed to pass from one side to the other, are those to do with the Internet services which the server suite supports: web, email, FTP, newsgroup, and telnet information. Any other messages going round your school network -- for example, files being loaded or saved on network fileservers -- are prohibited from crossing the firewall and are thus safe from external attack. You can see this in the diagram, right. Email and other approved messages (1) are passed straight through by the server computer; unapproved messages from inside on your own network (2), such as attempts to bypass the server suite's access controls, are stopped and do not cross. Likewise, unapproved messages from outside on the Internet (3), such as illicit attempts to access your fileservers, do not reach their targets.
	Authenticated services
	Users of the ANT Internet Server Suite must log on to the server computer before using any of its facilities, even sending email or using the web. This has two main benefits: firstly, it greatly reduces the risk of people outside your network using your server (either for its own services or as a "staging post" for attacking other sites); and secondly, it lets you, the administrator, find out which of your users was responsible for each of the server's actions.
