Work History

Senior Network Security Engineer (5 years 5 months)

ExxonMobil Business Support Center Malaysia Sdn Bhd

Responsible for enterprise security using Firewalls and IPSes to protect Corporate, DMZ, Process Control, Terminals and External 3rd Party connections, mainly using Cisco with IPS and FirePower and Juniper SRXes

During a network refresh project, was able to reduce number of firewalls deployed from 28 to 2 pairs thus reducing capex and maintenance by developing new standard network design using VRF which combines old Process Control Networks and corporate network within the same physical network, without sacrificing security

During a distribution terminal server refresh exercise, redesigned the distribution terminal network to include a new DMZ security zone that assures separate controls can be applied to traffic from Corp to the new server and from JV Partner (new requirement) to the new server.

Ensure continuous support from access control infrastructure (RSA SecurID) by migrating the old RSA 6.1 authentication manager which is out of support to latest version 8.1 smoothly without interruption to business operations and within a short span of 6 months even though I have no prior knowledge to the system operations
