  • This is an animated video explaining what a network firewall is. A firewall is a system that is designed to prevent unauthorized
    access from entering a private network by filtering the
    information that comes in from the internet. A firewall blocks
    unwanted traffic and permits wanted traffic.

      Is a firewall a different networking device or just a virtually installed with OS? This doubt is because you said some computers have pre installed firewalls.

However, when I see these videos explained so clearly, it changes my whole look outlook on my abilities and the IT field. I can't emphasize how much these videos mean to me. Thank you!

    My understanding after watching this video is very vivid. The simple way I understood and will teach others in the future is that our network is like our house. Network based firewall is the main gate and host-based firewall is the door of room. Former protects the whole house and later protects the specific room. Both are needed to be safe from intruders.

    Years ago I worked for a large government agency that dealt with incredible amounts of sensitive information.

After a 6 month background investigation I was offered the job and yet somehow during my first week of training they never even mentioned firewalls. Given everything we did on a daily basis and the amount of critical data we possessed (seriously), I’m certain they must’ve had one…. But we never heard about it. Thank you for these videos.
