Noorg Incorporated is a New York based consultancy specializing in Unix and Linux system administration, computer security and networking.
As company founder, Joshua Birnbaum has been working as an independent contractor since 1998, providing expertise to such business sectors as advertising, the financial industry, the computational sciences and Web development.

Mr. Birnbaum began his system administration career in 1994 within the advertising industry as a member of the computer systems and network support group of Frankfurt Balkind Partners, a Mid-Town Manhattan based advertising firm. His responsibilities there included all aspects of the administration of over one hundred Macintosh design systems in addition to the wire level maintenance of the ethernet network to which they were connected.
The latter addition of Silicon Graphics and Sun SPARC hardware running the IRIX and Solaris (SunOS5.x) operating systems respectively, provided Mr. Birnbaum with an entry point into Unix system administration and beyond that, Unix system security and practice. In addition to this, it also provided an introduction to C programming on Unix systems, an endeavor that first began on Macintosh and resulted in the release of Geoport Shutdown, a management utility for the Apple Computer Geoport modem that enjoyed exposure on such sites as MIT's Info-Mac software archive.
ifchk, a computer and network security tool, marks the first open source software offering from Mr. Birnbaum. More information on ifchk can be found here.

Australian born, Mr. Birnbaum grew up in Asia after which time he moved to Europe. He arrived in New York in 1993 where he has resided since.
