You may not take even a second to respond. But if I may ask "How much does Google know about you"? You may instantly reply "Wait... what!? Do they!?" The book "Googling Security: How Much Does Google Know About You" by Greg Conti (Computer Science Professor at West Point) is the first book to reveal how Google's vast information stockpiles could be used against you or your business and what you can do to protect yourself. http://www.linuxsecurity.com/content/view/145939 --- A Secure Nagios Server ---------------------- Nagios is a monitoring software designed to let you know about problems on your hosts and networks quickly. You can configure it to be used on any network. Setting up a Nagios server on any Linux distribution is a very quick process however to make it a secure setup it takes some work. This article will not show you how to install Nagios since there are tons of them out there but it will show you in detail ways to improve your Nagios security. http://www.linuxsecurity.com/content/view/144088 --> Take advantage of the LinuxSecurity.com Quick Reference Card! <-- --> http://www.linuxsecurity.com/docs/QuickRefCard.pdf <-- ------------------------------------------------------------------------ * EnGarde Secure Community 3.0.22 Now Available!
