What is a DMZ? (Demilitarized Zone)
HTML-код
- Опубликовано: 27 сен 2024
- A DMZ, or demilitarized zone, is used to help improve the security of an organization’s network by segregating devices, such as computers and servers, on the opposite sides of a firewall. And setting up a DMZ in your home router designates a device as a DMZ host and will forward all the ports to that device.

This is what schools are supposed to be: Good old-fashioned simple animations with commentaries crystal clearly breaking down complex concepts and emulating them into real-world practices. No bs, just what it is, how it works, and what it brings about. I dont mind writing essays, but I do mind writing essays for professors to assess who cant clarify the simple difference between Ipv4 vs Ipv6. Boy i was 5mins in the lecture and started googling and got everything I needed from this channel...

schools are for hour long lectures you will or will not need in future but honstly most of it wont be needed
Most people have to use 2 sometimes even 3 4 or 5 sources to study for each IT cert they get. This is cause not everyone explains stuff in a way you understand. So each source might only explain some of it in a way you understand. That's why to learn it all for a cert people use many sources. If it was so easy for everyone to understand instantly then IT people wouldnt get paid well if just anyone could learn it without almost no struggle or effort.
my mind went to the school shootings
when you've been in IT for 10 years and heard these words thrown around and by this point you're afraid to ask.. these videos are gold!
Should never be afraid to ask
This video is amazing!! During my Network + studies, they talk a lot about NOT using Demilitary zones on corporate networks and i don't understand why?? This video explains it's uses and why it's beneficial. Also, NOBODY has every explained(except this video, smiles) how the DMZ is utilized in a home router setup. The XBOX example is very pertinant and is a great example of how to use that feature at home.
Thank you.
In a corporate environment it is important to prevent unauthorized access to data storage servers. It is those servers you do not put in the DMZ
@@stephenhunter70 Well in a corporate environment, what devices are you allowed to put in a DMZ? What devices have you seen placed there? Thanks.
In a corporate environment you are allowed to put whatever your client has authorized to be put there. The real question is what would I put there!
Kenneth White some put their Webserver, mailserver or cloud storageserver there. Just as examples.
when you're trying to look up a documentary on the Korean war and you stumble upon this
you must be an idiot.
TJ NightTrain you must be insanely fun at parties.
wait this isnt about Korea?!?
Joseph Fox it's about computer networking.
@@dusscode ah yes computer networks in korea
I teach IT at the high school level. Your videos are one of my greatest resources. Our students take the CompTIA IT Fundamentals exam their first year and the Microsoft Networking Fundamentals their second year. I can not thank you enough for your help.
Thanks
Two useless Certs: IT Fundamentals (is it still around?) and Microsoft Networking Fundamentals (never even heard of it). High school students should be studying something like CompTIA A+ or Cisco Academy CCNA modules (full CCNA might be tough for HS kids). Agree that these videos are a wonderful resource as are Professor Messer (sp?)
3:41 Love the toxic skulls spitting out from the first firewall. Great video as usual!
:)
Hands down one of the best presentation I have ever seen. I've been in school for 5 years haven't came close to this great of a video like this. Animation was on point, Summarizing on point, and give me extra content such as connect it to gaming console. I'm actually going to try this out. Thank you a million, you've help me tremendously, sir. Happy holidays, and New Year. :)
Thank you.
How are his explanations so easy and crisp! He even put in a explanation and quick guide for a home DMZ! You are just amazing!
That home router animation was so captivating!
Exactly my thought
whenever im stuck on a concept, i come to your videos. Thanks
Such a simple way to describe and advance computer security aspects. Thank you
I always come back to this video when I try to remember of explain an DMZ. This was so clear, concise and easy to understand.
I've been watching A+ videos to study and DMZs popped up and nobody explained it well, but this video is incredible! you actually explained it perfectly, thank you
This videos zipped hundreads hours of study. Thank you.
Most clear explanation of a DMZ I've ever heard, thank you very much!
Nice! Been switching my brother over to 5 GHz on our secondary router Sunday and noticed this option. Was wondering what that was (besides parent's initials!) Decided to look it up later and was surprised to find it in my feed yesterday from you! Caught me off guard! Didn't even have to search for it! This amazing timing tends to happen a lot! Especially with TechQuickie! Nice job, really helped! Saved me time too!
One of the most underated IT channel on youtube. Subscribed!
Studying for my A+ , this is by far the easiest video I have seen yet. Awesome job
I highly recommed this outstanding video to everyone who is familiar with networks, since i bet that 99% of them including me won't know the DMZ term in router 😁
Now I have a new 2nd place to go for IT.. Professor Messer and this guy.. wow.. great explanations on how things work.
You can do more in 10 minutes than what 20K tuition does in 4 years. Keep the videos coming, I learn every single time when I watch.
Agreed!
This has got to be the best channel to learn networking. I never leave here without understanding the topic!
4:33 thanks for giving me one good reason on why we should have a game console at home
I agree I honestly am learning more on these videos than I am with the school content. Thank you.
Dude! Thank you so much! You have no idea how hard it has been just to get a basic summary on what this is!
DUDE, your videos are so easy to understand.
Your vids are the absolute best on the subject matter you cover. Concise, well presented and very useful in helping me understand these concepts and topics. Thank you!!!
Very clear and easy to understand. Thank you! Also really enjoyed the animation on the router at about 3:50.
This is the best explanation about DMZ I have ever seen. And I've seen a LOT (mostly bad). And your animations are amazing! Thank you for your videos.
Thanks
Crap! Don't you know dmz computer has local network ip address? Meaning once it's hacked, it can easily access other computers in the LAN?
honestly i love how you explain things...
Thanks
very useful and easy to understand. I have heard DMZ a lot but can not understand clearly, and why we have to use DMZ area in network to secure
Best explanations ever on DMZ, especially for Home Router part was awesome!
Your tutorials are the BEST here on RUclips!!!
I'm an IT guy, and this is an excellent YT-channel.
Great video, especially the graphics. I can't help thinking of something I was taught in school; "a picture says more than a thousand words", especially on complex subjects.
Great, simple, and nice explanation. Thanks! I will use this video to explain my classmates the DMZ.
I was wondering when you were going to add the second firewall in front of the web and email servers. Then bam you put it in, good job and a great video for those just starting out in networking. Thumbs up.
Thanks.
I absolutely love this channel.
Finally I understand what a DMZ is !! Thank you so much PowerCert.
god, these visuals are so good...makes it SO easy to understand
This has been one of the most clear and helpful videos in my IT studies
I wasted 6 minutes learning something I already knew.. Now that's dedication.
Nice video, thanks for respecting our time by making it short.
clear explanation of a DMZ ever meet! thank you sooooo much
Simply amazing and easy to swallow. Great job PowerCert.
Your way of explanation is just mind blowing.
"In the real world, a DMZ is an area where the military is forbidden" - Not quite if you've been to the North-South Korean border DMZ
The parts with soldiers are not in the DMZ. The DMZ runs right through the middle, and aside from some special events any soldier from either side stepping into the DMZ would be committing an act of war.
@@NaptownClassic Like the neutral zone between federation and romulan space
The DMZ itself is filled with landmines if im not mistaken.
Thanks that was really a short and absolutely to the point explaination
Good Job. I love the way it was explained. Kudos and I have downloaded the video for future reference.
Your explanation is clear cut. Love that. Please also include practical lab snippets when necessary
what a great and clear explanation thanks a lot
thank you for explaining it both in a company sense and home network sense!
Someone buy this man a damn coffee!! Kudos sir!!!
Wonderfully explained. Thank you.
i havent seen such well explained videos
Thank you.
The security professionals I know scoff at the term "DMZ" to describe any configuration other than the two-firewall arrangement starting at 3:25. An aspect of operating a DMZ that you didn't mention is that each system running in the DMZ should run an image copied from a server in the protected area, and that image should have strong reference hash associated with it. A monitor should recompute the hash for each system periodically and compare it with its reference hash. Any malware that might find its way into the DMZ will be detected by the monitor, and can be immediately replaced by its reference image in the protected area.
As more people work from home in the post-pandemic era, the demand for increased security will escalate. Many or most employers require their home workers to use an employer-provided system for company work. That system should NEVER be on the same private network as the other devices in the home - especially if any of those devices is accessible from outside.
The proper configuration of a home network might be a good candidate for its own video. The security professionals I work with recommend one firewall at the connection to the outside, and another firewall for the devices from each employer (a home with two remote workers would therefore have at least three firewalls). The result is a private network segment for each employer, with shared resources on another private network. Any cloud-facing device is configured in the (real) DMZ.
Lmao if they want that they can pay for it.
Best explanation I found on youtube
I love all ur tutorials. There are well explained even a person who has no idea about networking can get some info from ur tutorials.
Amazing and clear explanation. I was reading up and down the web failing to understand that. You helped me a lot thx
Thankyou. I am on chapter 19 of my Comptia Net+ Book by Mike Meyers, and this video helped to explain this plainly!
lol I know people that will flip listening to this! But u agree with you 100%
I’ve followed n subscribed! Thanks for sharing what everyone has in mind
Thank you so much, i could get portforwarding to get to work but now i just know i can use a dmz👏🏻👏🏻👏🏻
I could give you a big hug right now
Thank u for ur explanation,,,
Could explain more about security like email gateway security
As a kid, I wish I knew that DMZ trick for my console.
fun fact: i found this video & this channel only because of wiimmfi error 86420
so greatly made thank you very much for sharing the knowledge
Omgawd thank you! Keep up the videos! This is helping me with comptia!
Wow. This was a REALLY good quality explanation.
DMZ in the real world: no more weapons
DMZ in the computing world: no more firewalls
Great video thank you
Simple and Easy!!! Thanks!!!!
very well explained DMZ in a simplified manner keep up the good work...
Best explanation videos in the world! Keep up the great work!
Thank you! DMZ and proxy server clearly explained. +1 subscriber
Beautifully explained for newbies like me. Love the animated graphics. Thank you.
You really are the best you have helped me with a lot, thank you so much. :)
Fantastic Visualization. You have shown the concepts visually. Thanks a ton. Please make more vids. Great you are helping the community.
This video is everything I needed and more. Thank you.
Excellent videos, nicely explained.
Best explanation ever!
Finally I know what a DMZ is! Thank you!
really very good explanation
Awesome video i had issues with my xbox being on a strict nat type but thanks to dmz my ports are all open and my nat type stays on open all the time 👍🏻
extraordinary explanation
Excellent video. Really explains the DMZ in a concise and useful way. Thanks.
Thank you.
A very good explanation! What i dont understand is what you mean by "inside" and "outside" the firewall. Most network firewalls have multiple legs/interfaces you can configure into security zones of different levels, so that you can create a zone for the dmz in your terms "inside" the firewall, without it being on the same zone or even subnet as the rest of your lan. If you are setting up a dmz with your topologi using only one firewall you will not have any control of the network activity on your dmz, as you have your dmz "outside" the firewall. I belive that the dmz should have some sort of security. Not trying to be a smarty, just trying to educate myself and others. I think your videos are really good!
very good explanation.thank you.
Thank you for simplifying what others make a pain in the ass explaining! you now have another new sub! keep up the good work!
Such a good explication, in the book is so much beating around the bush that the bat got green in color. THANK YOU! subscribed! Will use DMZ for faster connection on my PS3
did you even watch the video? Dont do it. Stuppid risk to take unless you acctually know networking and computers.
I love your art! Your animations are so cool and very didatic! I love doing powerpoint animations and design, so you're an inspiration for me!
thank you sir for teaching me this.
I am now almost at the end of my Study as an it technician, I must honestly say that this guy is simply the best at explaining things to beginners, there is no one better. He explains everything as simply and clearly as possible so that even beginners are not confused. Sometimes I have the feeling with him that my grandma who has nothing to do with it could understand him. Keep up your great job!
Thank you for these amazing and well-prepared videos 🙏
I wish I could subscribe and like this video 1000 times as a token of appreciation.
Great, informative, easy to understand tutorial video, 5 stars for you sir..⭐⭐⭐⭐⭐
An important thing to do with the firewalls, is to use different settings and if possible, use a different brand of firewall for the DMZ. This prevents hackers from bypassing 2 firewalls with 1 method.
SUPER FANTASTIC explanation! In term even I can understand! Thank you so much for taking the time to make this video!
Please create more videos,i want to learn more
Excellent explanation
You are a gem!! Your videos are very intuitive. keep it up.
What an amazing channel.
Excellent video, thank you.
