EMC Corporation, now DELL, a world leader in data Storage. Promoting data backup and recovery along with providing solutions for cloud computing.As part of the Global Security Organization, I had the opportunity to design, implement and manage the network packet capture tool for the Critical Incident Response team (CIRT). The opportunity to help the CIRT grow and build the Security Operations Center (SOC). I evaluated the CIRT needs, network traffic, network design, data retention, business functionality needs, requirements and etc. With that information I architect'd the whole packet capture infrastructure from ground up. The tool of choice, obviously was RSA Security Analytics Packet (NetWitness) which I was very familiar with.I spent the 2 years, designing, procuring, deploying, configuring, testing, documenting, troubleshooting and training the operations engineer on the product. It was a great feat as it was world-wide.Along with RSA Security Analytics Packet, I also helped design, build and manage the SIEM which was RSA Security Analytics Logging (aka enVision re-platformed). Since I was very familiar with the RSA Security Analytics platform which was based off of Linux (CentOS).A short list here at EMC:-- Packet Analysis, Malware Analysis & Portable Executable Analysis-- Traffic evaluation, traffic shaping, network monitoring, system & service trending and analysis-- Architectural Design, Implementation & Support USBank, VISA, Johnson and Johnson, Boeing, DHS, CSC, ADP-- DAC, JBOD,& VNX Troubleshooting (storage)-- SourceFire Support & Administration-- Ironport Support & Administration-- Archer Support & Administration-- Mapr Hadoop cluster support & Administration-- VSS, Gigamon, Network Critical - Configuration, Troubleshooting, testing and evaluation-- Netronome SSL Configuration, Testing, troubleshooting and evaluation-- VMWare Virtualization - ESX ESXi 4.0, 4.1 & 5-- Policy Control, Assessment, and Documentation
