For a more comprehensive list of NT Security safeguards, see the NT Security documentation. Most hacks to WWW sites result from unauthorized users gaining access to your machine via telnet, ftp, sendmail or some other utility that allows them to upload data. After these two steps, you will have to manually copy any new files you need up to your server. The last security step to consider, is to secure the admin account so that someone can't re-open one of the above security holes and restart the server. These steps will help reduce the threat of system attacks but will not eliminate all vulnerabilities.
Additional recommendations are welcome.
There are no security mechanisms in place to prevent a mis-behaved CGI from performing unwanted activities. You should excersize caution before deploying any CGI script on the server. You can restrict access to a file or directory to authenticated clients by adding a restrict rule via the Security configuration. When you use authentication, no access is permitted unless a valid username and password are supplied. The Sambar Server only supports basic authentication.
