JP has been working with computers since the early Eighties and has been in the IT industry since the early Nineties, specializing in Information Security since the late Nineties. He spent a lot of that time working as a consultant but is now a Senior Security Engineer for BT MSS (i.e., BT Counterpane), after moving over to Engineering from Operations in March 2005.

Mr. Vossen has worked with DOS, Windows, UNIX, VMS and AS/400 platforms, with duties ranging from first-level technical support to network and security architecture and design. He currently loves to work with Linux, Perl, Snort and other Open Source and Free Software but is otherwise not much of a programmer. Unlike many of his technically inclined colleagues, he also enjoys writing and documentation, which has led to the publication of various InfoSec articles, scripts and tips.

JP is also a CISSP and member of CSI, ISSA (Delaware Valley), InfraGard (Philadelphia Chapter), SANS PANTUG PLUG and other industry related groups.

  • See the Winlocgcheck page for my Windows port of logcheck, the famous UNIX log processing tool. You can also download the PowerPoint presentation I gave to the Philadelphia Area Network Technologies User Group (PANTUG) on September 12th 2001.
  • I have written a couple of management scripts for CheckPoint Firewall-1 (LogSwap & CPFWBack). See my CheckPoint Firewall Tools section for more information.
  • I have also packaged an NTP service that will run on a really hardened NT server (unlike the non-free MS TimeServ service). See my CheckPoint Firewall Tools section for more information.

See my Bio above.

I have worked with many small and mid-size companies in eastern Pennsylvania and New Jersey. I have experience with companies in a broad range of markets, including Pharmaceutical, Financial, Healthcare, and Manufacturing.

I have worked with networks from Netware Lite and Netware 3.x on up to 30+ site TCP/IP WANS. I have written programs in COBOL, Pascal, C, BASIC, Perl, Bourne Shell and many application macro languages including VBScript. I have also been a beta tester for Microsoft (Win95 & NT4), Symantec and others.

What I like to do:

I am kind of a generalist rather than a specialist, one reason I have concentrated on Information Security--it is a very broad and far-reaching topic. I would rather have several different types of jobs and tasks than a single monolithic project. Of course, many projects involve a number of components, and that can be fun too.

While I am quite capable of doing both, I find I enjoy the tactical side of things more than the strategic. I really get into the nuts and bolts of how best to accomplish the goal. Here is a sample of things I enjoy doing, not in any real order:

  • Information Security engineering, architecture and design
  • System & Tool Automation (shell scripts and Perl)
  • Technical writing and documentation (really!)
  • Perl & Linux (mostly Debian and Ubuntu, with a dash of CentOS)
  • Broadband security and so-called "personal firewalls" for SOHO use
  • Hardening systems (mostly Linux, a little Solaris, some Windows 2000 and I used to do NT4)
  • Network Appliances, especially Network Security Appliances
  • Did I mention Perl & Linux? :-)

My Education:

I went to Oratory Prep High School, in Summit, NJ.

I also have a BSIS from The University of Pittsburgh. University of Pittsbugh Logo
