When I write reviews of various Linux distributions and describe differences in performance I almost invariably get a comment to the effect that all Linux distros are essentially the same: running the same kernel, the same libraries, the same filesystems. Performance should be essentially the same, right? The answer is a resounding no. The performance results of different distributions, even ones running the same kernel version, the same core libraries, and the same filesystem can be very, very different.

Authentication is a the key component of security-based solutions. In client-server models designed over UNIX® systems, distributed network security is of significant importance. In order to meet the stringent security requirements necessary in client-server models, either multi-layer authentication or multifactor authentication or combinations of both are being used by existing systems. This article discusses the risk associated with the use of the same security mechanism in multifactor authentication systems and proposes the use of GSS-API Generic Security Service available with most of the UNIX systems as a suitable option for achieving the multi-security mechanism clubbed with multi-factor authentication for enhanced security for solutions designed over UNIX.
