Security Issues

As with any Internet-based service, security is important when using WWW:

Make your network and systems secure, using firewalls, TCP wrapper programs, message logging, security enhancements, and audits.
Make your HTTP server secure:
- If you're using NCSA httpd, upgrade to the current version, or use the security patch.
- Configure the server with sufficient access controls.
- Write CGI scripts with great care, or avoid them entirely.
- Disable server-side includes where possible, especially for any CGI program directory.
Make your documents secure:
- Don't publish what you don't want the world to see, or use appropriate access controls.
- Restrict options on user home pages.
Make your Web clients secure:
- Configure to use external viewers that are safe.
- Be careful, especially with PostScript viewers.
- Don't allow clients to run shells as external viewers.
