Curriculum Vitae

While working with EUnet/Esat Net, in a support position I gained greater insight into the operation of DNS, smtp, proxies & firewalls and many other setup/diagnostic/resolution issues with a wide range of systems, as well as internetnetworking technically incompatable systems. I've also dealt with some of the 'politics' involved with dealing with other isp's / internic {& IEDR for .ie domains}, and I've had the experience of working directly with many IT managers in many large organisations, this has given me great insights into the uses and applications that buisness want/ need & can take advantage of.

Also I have been involved in the setup and management of a .ie domain and have been managing the Primary DNS server myself, also the web, mail and the other servers for the domain, this has been a huge learning experience as it was my first opportunity to install & administer Live Linux Based systems from start to completion

when working as a Senior Technical consultant for the Network Services group within esat net. I was involved in recomending solutions for customer internet connectivity/security needs, and then implementing (and troubleshooting should problems arise later) these solutions. Also I was regularily involved in troubleshooting and diagnosis of problems with 3rd pary setups, where either the 3rd party is unable or unwilling to provide support to the customer with the problems they experience when trying to configure the system to connect to us(esat net). Typical cases would be, troubleshooting ISDN line connections being brought up {to often} by misconfigured nt services/desktop machines, Limiting access to open mail relays on customer sites with mis-configured mail servers, Setting up firewalls / proxies /mail-servers/ viruswalls etc., Configuring cisco routers for leased-line & ISDN ip based wans and internet connections, also any 'never seen before' problems/systems I was normally the Technician sent out.

While working as a Security Architect for Internetworking Strategies (Ireland) Ltd. I was involved in all my previous duties with more of an emphasis on security and security auditing {including penetration testing, OS hardening etc.}

Now while self employed I am involved more with custom solution, ssh based remote control/configuration/repair, systems that mail alert customers and myself of any possible intrusions/alterations/anomalies etc. mainly for more secure firewall-1, mailserver & webserver implementaions, this lowers support costs for the customer and increases their confidence in their security. Also running diagnostics such as penetration tests site and system auditing, troubleshooting network issues, setting up vpns {from wan mesh's to client server remote access vpn's}. Occasionally designing/reccomending/setting up systems in conjunction with customer IT staff so as to train them in the instalation/maintenance of further similar sytems. and a large amount of time on cleanup/troubleshooting of other companies installs that are underperforming/failing which often involves dealing with systems that i'm not familiar with but as the basics are always there i've had no failures so far except when the systems were clearly functionly incapable or implementation incompatible such as firewalls with no site to site vpn functionality etc. related work involves analisis and preperation of reports outlying why such systems were non-functional {innappropriatly supplied} to aid customers to get the re-funds they deserve.
