Setup a simple Bot Trap for your website or web application that can enhance the security of your server and prevent malicious bots or script kiddies from poking around by luring them into a trap and banning their a**es for x amount of minutes, or else.
This explains how to quickly setup the amazing fail2ban, which monitors your log files for activity you specify and performs certain actions once a threshold is reached. Simplest case: Monitor authlog for failed ssh login attempts, and ban the originating IP after a few tries.
Chrooting has been around for a long time now. Chrooting makes a program believe that the root of the file system is higher up in the hierarchy. For example, if I wanted to create a chroot in /chroot/httpd, a program executed from within the chroot would believe that “/chroot/httpd” was actually “/”. There in lies the beauty as the program can’t reach any files outside “/chroot/httpd”. Security of the server as a whole is increased due to the fact that the system binaries are off limits. In addition, chroots usually only have the bare minimum files inside, so exploits have a harder time breaking in.
