Canada departments and agencies will have transitioned to a single, converged, and modern email
system. Mr. Stewart’s involvement includes regular policy meetings and design reviews both with
internal Bell Canada stakeholders (including senior management) as well as Shared Services Canada
(SSC) stakeholders. At the same time as the network was designed, implemented and configured,
Mr. Stewart has engaged in information transfer, coaching and formalized training of Security
Operations Centre personnel at Bell. He shepherded the SOC team through detailed testing and signoff of the production network and his network component was the first past the post for sign-off with
the Crown.
Representative Projects 2 (November 2012 – February 2013 and October 2013 – March 2014)
Corporate Security and Facility Services of the Bank of Canada (w/ Juno Risk LLC)
Network Security Architect
Mr. Stewart was part of a team which conducted a thorough review of the Bank’s virtualized data
centre network infrastructure which culminated in a detailed gap analysis as well as specific
recommendations as to how these security gaps may be closed. Extensive use of Cisco and other
vendors’ best practices as well as ITSG-22 and -38 are crucial, as is knowledge of the Cisco ASA
firewalls, virtual contexts, Nexus switches and Cisco VDC (Virtual Data Center) architecture and
TrustSec that are employed in BoC’s highly virtualized architecture. Subsequently, Mr. Stewart was
asked back to map out and document all network segments operated by BoC with an eye to mapping
the network security policy to a zone based security architecture more closely aligned with industry
best practices.
Representative Project(s) 3 (July 2012 – September 2012, and January 2013 to present)
University of Ottawa and International Joint Commissions (w/ Bell Canada)
Network Security Architect
Mr. Stewart reviewed uOttawa’s network security architecture and implemented two Cisco Firewall
Services Modules (FWSMs) in an Active/Standby Failover configuration at the Internet perimeter.
As part of the effort he rationalized and simplified the rule set logic of a cutover from the pre-existing
DrawBridge firewall to the new firewall architecture.
At the IJC, Mr. Stewart installed and integrated an A/S FO Cisco ASA pair supporting both gate-togate and client-to-gate VPN functionality using respectively IPsec and Cisco AnyConnect Secure
Mobility Client solutions. Subsequently scaled the solution by adding remote access by Cisco VoIP
phones via AnyConnect and integrating with Cisco UCS at the client headend in both Ottawa,
Windsor and Washington DC. Mr. Stewart is currently working on a SoW which, when agreed, will
modernize the IJC network to include a site-to-site Dynamic Multipoint VPN (DMVPN) using newly
purchased Cisco IOS routers at the main and satellite offices of IJC as well as a migration to full
