The Complete Guide to Hack Proofing Sun Solaris 8

"As a child, my father and I tried to design a birdfeeder that was easily accessible by birds but impossible to reach by squirrels. Our birdfeeders ranged from the simple to the absurd. Each design worked temporarily, but eventually the squirrels would figure out a way around our defenses. Our efforts were helping breed a smarter, craftier squirrel. The "Ultimate Squirrel-Proof Birdfeeder" scenario is similar to the challenges we face in computer security. How can we provide easy access to resources by the authorized users and still deny unauthorized access? Luckily, as Solaris System Administrators, we have some excellent tools available to us. Sun Microsystems has spent a great deal of effort in designing Solaris to be both stable and secure. This book is your reference guide for not only securing your Solaris systems, but also for securing the environment in which they operate."

1. Configure Default Settings on a Newly Installed Solaris 8 System
Review the basics of testing, monitoring, and documenting security procedures.

2. Learn about Third-Party Security Tools to Secure and Monitor Systems
You will find recommendations of valuable tools to have on hand, where to get them, and how to configure them.

3. Manage How Users Are Authenticated
Securely identify your users, reject those who don't belong, log failed access attempts, and revise the system as new threats arise.

4. Understand How to Secure Your Files
Configure file permissions and commonly used protocols such as FTP and NFS to transfer information safely.

5. Explore Options for Providing Secure Network Services
Provide secure access on both sides of the router.

6. Provide Secure DNS and DHCP Services to Network Clients
Harden your Solaris systems' network services so an attacker won't easily succeed with remote attacks.

7. Configure a Secure Web and E-Mail Server
Provide your network users secure and stable access to e-mail and the Internet.

8. Configure Solaris to Be a Router and Provide Firewall Services
See why Solaris is a good choice for a router. Combat Code Red! Use Perl scripts to identify the Code Red URL and counter attack.
