Tim Brown joined Cisco as part of their acquisition of Portcullis for whom he worked for almost 12 years. He is equally happy performing white box assessments with access to source code or where necessary diving into proprietary binaries and protocols using reverse engineering methodologies. Tim has contributed to a number of Cisco's bespoke methodologies covering subjects as diverse as secure development, host hardening, risk and compliance, ERP and SCADA. In 2016-2017, Tim looked at targets as varied as Active Directory, z/OS mainframes, power stations, cars, banking middleware and enterprise SAP Landscapes. Outside of the customer driven realm of information assurance, Tim is also a prolific researcher with papers on UNIX, KDE, Vista and web application security to his name. Tim is credited with almost 150 vulnerability advisories covering both kernel and userland, remote and local. Tim particularly like to bug hunt enterprise UNIX solutions.
