@@mrnmrk6191 are you in the network berg chat often talking about MTKs? If so we have talked. I concur that Mikrotiks rock and def easy to learn, but the certs are harder to get and require a lot more. The CCNA is more widely accepted and currently respected, so while MTKs rule and I love them and use them myself on a few networks, I would not say the CCNA cert is something one should give up, some of the tik language, and most of other routers, are based on cisco so all around a good cert, it is better than a network + for sure. Once Mikrotik makes their certs affordable and not a required class to get it, then will jump on that cert wagon lol

The most common approach is: a lock on the doors and security personnel The next step is authentication of each deive on the port 802.1X. The next step is IPSec.

You can spoof Mac addresses. So if you unplug a Pi from the switch, you might just take the Mac of that Pi and the mac filter is irrelevant. This is an inconvenience for the attacker, but be careful not to overstate the gained security there. Mac addresses are often just written on devices, otherwise just plug it into your own switch and read the mac from there. Furthermore, in a real life scenario, you run in a huge problem if an attacker gains direct physical access to the switch, but I guess everyone is already aware of that ;) Overall nice content, thanks!

Security is all about layers. Usually when a device is hard linked to a port it provides a certain service. Sure you can spoof the mac address, but for a network printer I can disable most networking. I only have to open certain ports and when you spoof the MAC address, you can only do things that the device could, but nothing more. I'm an old-school administrator. By default I block/deny everything and than I open up the things I need. It is not user friendly and when something needs to be connected, I takes some time (sometimes several hours) to setup everything. This concept is working for me for over 25 years going back to my Netware days. Given enough time, opportunity and resources everything can be hacked. If someone is specifically targeting you, there is usually very little you can do about that. But by securing your switch in a proper way, you can guard against 99% of the attacks out there...

not to mention that in his example, the sharkjack has already cloned the MAC of the existing raspberry Pi. which makes his example terrible.

@@mathbee It's not cloned. The last two digits of the MAC were indeed different. The Pi was d9, the sharkjack was a9.

This series has been massively helpful. I know you are crazy busy running a community and a business, but I would really love to see this series completed

MAC's are easily cloned. Which is why you need to pair up port security with 802.1x machine certificates

I think you do a really good job when it comes to fast paced dictation, most people stumble over their thought processes or skip steps, you stayed on track the whole time while making it enjoyable to learn. I wish all IT channels were as entertaining and captivating as yourself when it comes to teaching new users. Keep up the good work sir, subbed.

Hey Chuck, First.... I love your channel and your teaching style is superb! Second, When do you think EP 15 might be coming? I'm hungry for more !

I'm 3 months into getting my bachelor's in cybersecurity. So glad I found your channel. You explain things very well and it helps me out. Thank you.

Thank you for popping up in my feed today! I have been slacking off on studying and pushing my way into the IT universe after getting shot down after 4 rounds of interviews for my first IT job. But your videos do a great job of keeping me on focus and how fun it can be! Thank you much and I appreciate all your work on your channel!

Thank you for doing it this way! Learning how to do the stuff is one thing. But seeing what its like "being attacked" looks like and blocking the attack looks like!

I love this!! I have to work with customers all the time where I have to tell them, "I'm gonna send the ticket to the network team and tell them to do a shut/no-shut on the port." I had an *idea* of what was going on behind the scenes, but it's so stinking cool to see it play out on screen like this!!! Thank you so much for what you do!!!

Loving this free CCNA course you've been doing. The way you talk about it you can tell your passionate and it makes it much easier to watch. Will you be doing a video on configuring IP addressing for data center's/offices?

Chuck, I don't know how you do it but I've been going to school for IT for about 2 years now and every time i start a new class you cover something about that subject. Thanks for your guidance you make some of the subjects easier to understand!

Would love to see more of this series. I have found it really interesting and really enjoy the way you present the information.

This was really interesting, parts of this I used for years, other things I had little knowledge about but you explained those things in a level that I understand. I not work with it, just an nerdy hobbyist. With your videos I have to rebuild my home network and play with the security stuff 🙂 Keep up the good work

I need to configure port security on a Cisco switch this week and you just happen to have a quick tutorial. Perfect! Thank you.

Dude, there is no one, absolutely no one on youtube with better network related content. I do hope you are getting rich from it and thank you, thank you a lot

I absolutely love everything about your content! Just how clean your explanations are and how much detail you go through using visual aid. As a visual learner, your videos are absolutely Paradise to me! Also, your comment about being in a black hole with no friends and you're sad reminds me of Loki when he says, "Yes, very sad...Anyway..." LOL!

Chuck, a good tip with working on multiple ports at once in cisco is interface range then you can put the range of ports you need to change and do it all with one command

Your videos make the seemingly daunting task of playing with the CLI on a Cisco switch surprisingly easy!!! Thank you.

I'm currently in OS Software and computer hardware, and Networking, but security is next once I re-learn all the stuff I forgot in my 20's. Can't believe how much I still know and is actually still relevant some 10+ years down the line. Did port security and observation old-school for so many years, a keychain shark seems too easy. I want one!

I have been doing networking for about 6 years, but never got a CCNA. Never thought I could do the cert. Your videos make me think I can. Thank you and keep doing the fine work you do

Natural born teacher. I love the way you teach. You make hard things look easy.

what a kick ass series man thank you so much for these! looking forward to the next video!

You are such an underratedly effective teacher of this stuff

Thanks man, Cisco auto learning makes it soooo complicated to digest while your course is easy to follow and understand!

Great video as always, wish you would have covered "errdisable recovery cause all" saving the babysitting of having to shut, no shut ports to recover from err-disable. Maybe you'll get into that in a future episode. Looking forward to spanning-tree and DHCP snooping trust. Well done.

Thank you man this is good content .. im following network engineering and cyber security degree ..these videos good for studies and for additional knowledge ..keep up the good stuff

You explain everything so nicely. I have never understood this concept before you.

I personally didn't learn anything new, but this was a good episode. I've never heard blackhole VLAN, everyone I've met in the industry for me personally has called it a quarantine VLAN. Port security is very important, thank you for sharing with everyone!

Has this series finished ? It has been 4 months since the last video 😔😢 Seriously .. you're the best instructor I've ever seen 🌹👍 Hope you complete the series very soon 😊

What an awesome video, super entertaining while also informative on the topic. Looking forward to your next CCNA videos!

What if the attacker determines the MAC-Address from the allowed device, and sets the MAC-Adress to it's hacking device? MAC-Address can be changed I think. Is there any way to handle this?

more ccna i been waiting the longest

I'm glad that you give use the run down and course for free so at lest we have some knowledge of how to secure a port

This was one of your more useful videos that I've watched; more advanced content plz!

Hi Chuck , I'm a huge fan and get very excited whenever your video comes

Thanks for the amazing content brother. Any chance you're able to tell us when this course might end and in how many episodes?

@NetworkChuck - Thank you for all your videos - you really have re-inspired me to get my homelab set back up. I'm now running an ESXI which I never thought I could do - THANK YOU

Great video! Exited for more videos in this course! When will more videos in this course come out? ;-) Cant wait

This is pretty awesome. I understand the process and how to do it but the Cisco syntax is not something I use often so it's very hard to get it to stick. Plus, the Privacy VCards is a great idea to protect your identity and not have your primary card set up for automatic payments when you don't know if you can cover something you may have forgot about.

Another cool thing you can use the Shark Jack for is making a rogue DHCP server. This is good for learning how to configure DHCP snooping and dynamic ARP inspection.

Thank you for the information. I enjoy your KZread videos.

With sticky mode, if you don't write the config, a reboot erases the learned MAC and you can plug any device in. Also good practice to give your VLANs a description, especially when doing very large networks.

So good, dude. You're an amazing teacher.

I had old port servers from like 1998 that were Linksys that I went through and learned alot!! Especially after I revamped them on today's newer 5G network back in 2012 when I was re mapping digital security infrastructure and tracking finances.

Love the channel huge help to my choices my mental health and brain function , thanks

You always help me out so much!!! Can you maybe once do a JavaScript or python tutorial on the side? I would love to see it, respect for your efforts in your video! If I can I would love to enter the goveaway

Keep these babies coming! Thanks for the videos!

Chuck, A couple quick questions about the Shark Jack, 1. Where dies it get its power? Is it PoE or does it have a battery? 2. Could you have it grab MAC addresses connected? Like use a coupler, grab the mac(s) of a device/cable you are unplugging, then spoof that MAC via a script config? BTW: I love your videos, i have been digesting your whole channel and your way of teaching is similar to my own. It is obvious that you love and live what you do. Keep it up.

You are very good at teaching.... very practical

"Put it in VLAN 666!" That comment has earned you my sub! Also, thank you for teaching this. Physical security is one of the things that I love seeing at the places I've worked (and hate when there is none). I've seen switches plugged into wall jacks that were left out in the open and since earning my BAS in IS&C, that is vexing! Also "swi po mac sticky" is a great command to run on cisco ports to ensure that no "new" devices get swapped for the one that is set for the port!

This is especially important for residential homes that have multiple Surveillance cameras outside house that can easily be knocked off to gain network access. Best practice dictates having multiple cameras recording other cameras in case they get vandalized.

I love chucks videos every one is a learning curve great content chuck

favorite dialog of chuck : Let,s hack youtube today ethically ,off course🔥🔥🔥🔥😂😂

Hey Network Chuck, I hope you can start working on this course again. This course is extremely valuable!!!

This is all great info, your content is awesome! One thing I might add though: If you unplug the raspberry pi and plug it directly into the shark jack, the shark jack can clone the RPi's Mac address, which would allow the shark jack to bypass port security by providing the same Mac address as the legitimate raspberry pi.

Love these videos and I'm learning a ton and applying to my home network. When will there be an episode on trunk port security?

I'd like to own one 😂. It's been a long time since I dabbled as a neutral hacker but anyway. I love your channel. And I thank you for sharing information like this for people's safety. Excellent 👌
