AREAS OF EXPERTISE (con’t)

Open Source Project Contributions:

2010-2025

I have produced more than 250 source code patches to the Snort

Intrusion Detection system and ClamAV open source anti-virus system, and have provided source code (pending review/accepted) to enhance the Snort Sensitive Data Preprocessor and ClamAV Sensitive Data Format/Data Loss Prevention processor to detect additional credit and debit card information, along with bank routing information being sent over data networks (including the internet) in an unencrypted manner.

Additional work is in progress for detecting medical diagnosis codes from ICD-9 and ICD-10 coding formats for detecting HIPPA and PII being sent in cleartext form over networks and/or the internet without encryption for both Snort and ClamAV.

Additionally, I am listed in the authors/major contributors/contributors

sections (via README/About/Changelog) for the following software applications:

Libpcap (Network Packet Capture Library)

TCPDump (Network CLI Packet Analyzer)

WireShark (Network GUI Based Packet Analyzer)

NMAP (Security Scanner for Port Exploitation)

ClamAV (Open Source Anti-Virus Scanner)

Snort (Open Source Intrusion Detection/Prevention System)

ISC DHCP (DHCP Server/Client)

ISC BIND (Domain Name System Server/Client)

ISC INN (Network News Server/Client System)

Bro 2.x (The Network Security Monitor)

In the 4th quarter of 2012, Sourcefire (now Cisco Systems) (developers of the Snort IDS and ClamAV) made me a member of the Snort team (under the major contributor section) for my code and documentation contributions to the Snort Open Source Intrusion Detection System.

As of the 4th quarter of 2015, I am now listed as a contributor for the ClamAV open source Anti-Virus system at www.clamav.net under the About link.

Additionally, I have written a guest diary for the SANS institute as part of their incidents website at http://isc.incidents.org entitled:

'Are you losing system logging information (and don't know it)?'

2004-2009

I have contributed source code to the Snort Intrusion Detection System for versions 2.4.x, 2.6.x, and 2.8.x; in which I implemented the configuration option known as –enable-timestats so that network/system/security administrators could get an idea of how much traffic snort is processing on an hourly basis, without having to stop and start snort, or by using SIGHUP to force dumping of data to /var/log/messages in a Unix or Linux environment. This was phased out in Snort version 2.9 alpha when SourceFire developed the performance monitor module, which gathers many more statistics than my original module.
