"Hang your server out in e-commerce land for any length of time and the odds are that, sooner or later, someone will climb over or tunnel under your firewall. That type of perimeter defense is almost as effective as birth control and, if breached, the result is almost as traumatic and expensive. Preventing hackers from hijacking your server usually requires more than just a barrier. According to Argus Systems, it requires PitBull LX."

"PitBull LX is the Linux version of Argus's Solaris- and AIX-based security software. Unlike firewalls that are primarily meant to prevent intrusion into your server but can allow access once they've been circumvented, PitBull LX's job is to deny someone access, no matter how they've intruded, even if they're logged in over the network as a super user. It does this by allowing you to create segregated access domains that isolate subsystems and processes from each other. You can then assign similar--or different--access rules to any or all of the domains you've created. If an intruder is detected, PitBull LX traps the intruder in the affected domain, leaving the remainder of your server otherwise untouched."

"PitBull LX is not actually an application. It becomes part of the Linux kernel and adds its commands. Don't worry about losing a weekend to patching and assembling; Argus provides an install script file on the CD-ROM that does most of the heavy work. Argus does note, however, that if you later need to build a custom kernel, you should also install the provided argus_kernel-source, which includes a prepatched Linux source tree and the binary modules needed to do a custom build."
