I have never used a Sun Solaris system, but I found this book to be very informative and enlightening nonetheless. Hack Proofing Sun Solaris 8: Protect Your Network From Attack provides an excellent introduction to securing a Solaris 8 system. It covers everything from securing the installation out of the box, to securely implementing Solaris 8 as a web server, email server, firewall or router. The information is presented in a way that will teach someone new to administering Solaris security what they need to know, but it may lack the depth to teach a Solaris guru any new tricks. Although this book doesn't relate to the most current release of Solaris, most people trying to learn about securing Solaris will still benefit from reading it.
