    I'm a CCNP for over a decade and always use your videos for interview prepping. Cheers.

      Great to hear. Good luck with the interview! You're going to nail it!

    Don't mind me just making myself some notes:
    Firewall
    - On a local network as an admin you have a great level of control on the devices and therefore can assure security but outside in the public internet you cannot
    - shielding/protecting a trusted network by blocking unwanted traffic from networks, while allowing desired traffic from untrusted networks
    - firewalls block everything by default, both outgoing traffic and incoming traffic
    - traffic is allowed by adding traffic rules that specify source IP, destination, port and action
    - Stateful firewalls monitor active connections therefore automatically allow response traffic if there was an initial request traffic even if the firewall denies all other incoming traffic
    Endpoint firewalls are made to catch the bad traffic that might pass the network firewall or if the threat comes from internally, inside the network
    - Having a firewall on both the network and endpoint is important to have a layered security posture and in case the threat is from an internal source

    I am not studying for CCNA, but for Security+. Your videos have made my learning so easy, so entertained. This has become one of my TH-cam favourite channels by far! Thanks a lot :D

    Your not the only channel I watch thats in the Networking Tech sphere on TH-cam as I watch many for content need and educational awareness, but I can plainly say you do a far more fantastic job by a wide margin to make complex technical info seem easily understandable, learnable, teachable and easy to remember thus learning the information. While I may not always remember everything because it takes time to mentally digest new info, it is the best presented information that can be easily learned. On some topics in the future, you could do a deeper dive on some aspects of many topics. However, to initially learn a topic you cover it superbly.

    I recommended your channel to our trainees at the company. The explanation is really easy to understand and I don't need to watch the video twice. I did understand a lot from your channel. Best regards from Germany 😀

    Quite clear without injecting too many other confusing detailed terminologies. Great videos for all levels of knowledge.
    Even if I may know some of the topics in your videos I still watch them because different explanations from different sources do help me grasp a bigger picture.

      Thanks for the comment Zackery! Glad you enjoyed my explanation.

    Wow that is a very interesting topic.
    It is well known that one picture is valueable more than 1000 of words. You have dozens of great pictures on your videos and that is why they are only to the point yet so good. The images help understanding the overall idea.
    I learned about the network firewall and about the firewall table that allowes the traffic requestd in its rows to pass and the replay of the request to come back and the else not. In addition I learned the important of end point firewall.
    The example of the rooms and front house door was very useful to see. The network firewall is the front door and the room's doors are the end point firewalls. Perfect example.
    Additionly I learned about NGFW and the importance of it from the security perspective.
    Keep up with your sharing of knowledge.

    how do you ensure firewall goals do not overlap?

    • @Certbros
      @Certbros  3 ปีที่แล้ว +1

      Sometime firewall rules do overlap. They can get pretty messy after a while if you're not carful. A firewall will read the rules from top to bottom and the first matching rule will be applied.

    Hi, what is the best software firewall for Windows and small office?? And we can block port manually on it for more security??

    • @Certbros
      @Certbros  4 ปีที่แล้ว +1

      Hi Martin. To be honest, the windows 10 firewall does a good job. Couple that with a good endpoint protection (anti-virus) and you should be good to go.
