Our responsibility towards IT Network Security

What is Information Technology (IT) ?

Information Technology (IT)
In a nutshell, anything related to computing technology is a component of IT.

IT in Home Computing : some components

IT in Home Computing
Non-exhaustive list :

  • Smartphones
  • Tablets
  • Laptops / Desktops
  • Smart objects used for home automation (Bulbs, doorbells, thermostats, etc...)
  • Internet Connection and ways to use it (WiFi, cables).

IT in Professional Computing : some components

IT in Professional Computing
Non-exhaustive list :

  • All components involved in Home Computing
  • Datacenters
  • Servers, hypervisors, storage arrays, etc...
  • Routers, switches, firewalls, etc...
  • Websites, applications
  • Public or private customer data

What about IT security in Professional Computing ?

IT security is the way to protect IT components from every kind of threat :

  • It has to be considered as a long-term insurance,
  • It must cover physical infrastructure as much as logical infrastructure.

IT Network : the key component to secure ?

IT Network : the key component to secure ?
With a strong predominance of Internet-related uses, network infrastructure must be considered the backbone of computer technology.

In addition to strong reliability requirements, more and more abilities were added to network architectures the time passing by, such as content inspection/protection layers against cyberthreats.

Everyone must be concerned about IT Network security. Why ? How ?

Everyone must be concerned about IT Network security. Why ? How ?
From the decision makers to the operations technicians, passing by IT Network architects, everyone should be aware of the importance of securing IT Network.

As mentioned upper regarding a more global scope, IT Network Security in Professional Computing must be considered a long-term insurance, that means :

  • A good knowledge of the scope to protect :
    • "Every fuzzy need leads to a very specific bullshit" : in less flowery language, security requires accuracy.
    • Security expectations evolve over time, and require some adjustments regarding configuration and service contracts.
  • Investments costs awareness :
    • Investing on network devices hardware and/or perpetual software licensing is a thing, considering that lifecycle policy to follow for such in order to keep a state-of-art infrastructure is about 5 years.
  • Operational costs awareness :
    • Typically, threat prevention features embedded in core network devices are tied to time-limited licenses. Those costs are cumulative with hardware or basic software support contracts.
    • In some cases, 99.99% SLA and 24/7 support is a must-have,
    • higher the security requirements are, higher the recurring costs will be.

Problem solving mantra

Life is succession of challenges...

... that we face on a daily basis :

  • Most part of those are easy to overcome, and are completed in a matter of seconds,
  • But some will appear overwhelming, and will take much time to achieve !

Nobody said it was easy...

With such assessment, we can agree that everybody need some waypoints to go through life.

Regarding my personal and professional background, that is a good example of this succession of ups and downs, I use a simple motto as my main waypoint, like a mantra which sum-up my approach for problem solving :

My personal mantra

If there is no solution, there is no problem. --- Unknown

I can't remember how this came to my knowledge, so I don't know who I can credit for that quote! Google Search hesitate between Buddhism (Dalai Lama) and Dadaism (Marcel Duchamp)...

How those simple words can affect a life path


Anyways, it has driven my decisions and choices at least thorough the past 15 years, with quite a good success :

  • When I switched from nurse studies to IT field for health concerns,
  • When I left my native area to work on Paris (France) following a dark year,
  • When my wife and I chose to emigrate to Canada at the very moment we felt that our lives needed to level-up !

How those simple words can help on a working routine


From my point of view, using this mantra as a decisional leverage, combinated with a solid professional expertise, is a good way to find relevant (sometimes out-of-bounds) solutions to :

  • some network and security designs that needs to be efficient with the lowest building and recurring fees,
  • blocking points you can face when you integrate some unknown technology,
  • the most critical issues when all well-known solving paths can't apply.

Make those words yours !

As it worked for me, I have no doubt that some of you will find out that this "mantra" makes sense ! And if it can help you to complete your daily challenges as from now, I will be more than pleased :)
