But as more and more "mission critical" applications are accessible through the web, administrators are turning their attention to the danger of attempted intrusion from outside the networked host. SATAN is a powerful aid for system administrators. It performs "security audits," scanning host computers for security vulnerabilities caused by erroneous configurations or by known software errors in frequently used programs. O'Reilly's latest release, Protecting Networks with SATAN, is an invaluable tool for network and security administrators working with SATAN.
Wietse Venema, SATAN co-author, says "In this handy book, Martin Freiss explains the workings of SATAN and provides a helping hand with customizing and extending the system to match local conditions." This concise guide also discusses how you can defend your site against potential abuse by SATAN.
