This video is honestly one of the most simple, yet clearly explained real life execution of a DMZ. I work in It Security and i've watched hundreds of videos that try to explain this concept but fail because of their lack of application. Videos that simplify concepts to a basic level help people learn better. Great job! 👍
How does having 2 firewalls provide better security & redundancy? The firewalls are protecting different elements. If one firewall goes down the internal traffic won’t be getting out since it’s in the path of outgoing traffic….?
Great question! Most firewalls are statefull. This means that if traffic is allowed out, then it will be allowed back in. I didn't show outbound rules here because they're not relevant to DMZs. Hope that helps!
Can a server in a DMZ pose a security risk to the rest of the network? Like if i put my playstation ip on DMZ network will it put any danger on my other devices if it got hacked ? Thank you in advance.
The purpose of a DMZ is to protect the rest of the network from the public facing assets. As for the playstation, other than a possible slight increase in network performance, I can’t think of any benefits.
Thank you for the vedio , One question and forgive me if it seems stupied : If I will block public Internet connection to my local envirenment (PCs laptops) based on firewall rules and only allow it to DMZ , How can I connect to the Internet to those laptops for exemple making search on the internet , watch vedio ...etc?

just like David Bombal
I'm a beginner and I simply love the way you explained with with animation and pictures. Thanks a bunch!!!
Great simplified explanation AND application. Since watching I'm thinking the public facing network should be on a separate provider circuit.

Is it DM-Zed or DM-Zee? 🤔
DM- Zee is the correct pronunciation currently being used in the industry
@@rahulsinghpatel9621 It was rhetorical, they are aware of that, they are poking fun at his accent.
DM Zed THANK YOU FOR SAYING IT PROPERLY AND NOT SUBMITTING TO THE …. (You know who) 😅
I guess it depends on pronunciation.
I love you for creating this video and explaining so beautifully ❤
Thank you for the info brother.
You're welcome!
Wish you big growth!🎉❤
Great presentation, man 👏cheers!
i was looking for DMZ call of duty but i stayed
appreciated as always, one of the best at making learning enjoyable and easy to absorb
Good stuff 👍
Thank you as always Orley!!
Subscribed, sir! This is great stuff.
Thank you! Happy you enjoyed the video.
Great video thanks for the animation to further drive the concept home.
If you block any other traffic (source WAN, destination any, port any, action - deny) then how workstations can browse Internet?
Great question! Most firewalls are statefull. This means that if traffic is allowed out, then it will be allowed back in. I didn't show outbound rules here because they're not relevant to DMZs. Hope that helps!
@@Certbros Thank you for your clear explanation ☺️ that makes sense
This is super useful. Thank you!
Great stuff as always! 💚
It's always a good day when Boson shows up in your comment sections! 😁
Thank you!
Excellent explanation 🎉❤

then how the web server talks to the backend?

That's blocking just incoming requests I think
