to simple authentication, to setting up Linux firewall such as the popular

ipchain or iptable, to using IDS snort for monitoring, this book has

plenty of examples. In addition to the tips on how to encrypt files with GuPgP, it also shows our readers how to set up openSSH for remote access,

as well as how to make email secure with IMAP/POP with SSL.

Not only does this book provide readers with an overview of what Linux

security has to offer, it also provides readers with a very practical

hands-on implementation. I also liked about this book is that the authors

will tell you about which packages come with SuSE Linux but not with Red Hat

Linux, as an example. This helps the reader a lot when you need to decide

what features to implement, or settle on what Linux distributions to use.

Job well done!
