PitBull Foundation is the company’s core product, and it is a layer of software that, the company claims, eliminates vulnerabilities associated with Unix the root or superuser account; the software also protects applications and operating systems from attacks from within a company or outside a firewall.

Argus has been selling the product on Solaris, and now it has been ported to AIX. Argus also sells a program called PitBull LX, which is a security layer that wraps around Linux or Unix applications and prevents hackers from exploiting known bugs in the application software to gain access to the systems.

PitBull LX also protects sensitive information and does not allow hackers to deface Web sites. Both PitBull Foundation and PitBull LX essentially provide a finer granularity to root access than Unix and Linux themselves. PitBull LX was available for Solaris 8 and commercial Linuxes based on the 2.4 and 2.6 kernels, and now it is also available on AIX 5L 5.2.

It is unclear when support for the new AIX 5L 5.3 release will become available.
