Understanding the TCP/IP and OSI models - how to categorize technologies by layer.
Early in my studies I struggled understanding what the OSI model was - and how to know what technologies went in each layer - I hope this video helps you understand what took me a considerable amount of time to unravel!

  • @FadiHelou73
    @FadiHelou73 4 หลายเดือนก่อน

    This is good but what kind of policies you are talking about? Lets say one of the employees was pissed off having a problem with his boss and his boss fired him and this employee is a smart ass he mirrored copy his device on a hdd usb or whatever after he leaves the company he will install the mirrord drive on another computer with all the policies and even can copy the MAC address that he had on the old pc so he will have access on the network and screw up everything, what I am pointing here is about the most important thing which is security and we need a kind of security that can’t be accessed in any way, as we know the is a security called ACL access control list that works for MAC address but unfortunately MAC address can be copied and edited, so for me this is not a security anymore but a new security called device serial number which can’t be edited that we can rely on for security, so at least we know no matter what happens its impossible to access a network if a serial number is not found on the switch itself before reaching the server even and searching for the rest of the policies that you implement in your system. The question is that do you think its possible to have a device serial number ACL on installed on the switch itself with the Mac Address ACL to work together in order to have a stronger security?

    • @dariopalermo2095

      Sorry, you're not getting it right. FortiNAC takes control of the switches and is able to change the VLAN you're connected to. It also sends CoA or Disconnect messages to the Wireless Controllers to manage wireless connections in the same way. So, let's say a disgruntled employee wants to create havoc on the former employer network and clone his former PC's hard drive: he will not have valid credentials for sure, and one of the enforcments the FortiNAC does is authentication. Even if the hacker wannabe finds his way into the office or connects to the wireless lan just from the other side of a wall, he will end up in one of the protected networks. The real issue is when the disgruntled employee had FortiNAC administrative rights: in that case he would know the policies and therefore he will be probably able to set up hi s PC to resemble a printer or some other device that bypasses the authentication: you want to have LAN segregation in place for this specific scenarios to minimize the attack surface (the hacker will enter a VLAN segregated and protected by a firewall at least so he will be capable of doing a lot less damage than entering the normal clients network).

    This is a really good explanation. The only part I don't get is how to access corporate resources like files (which aren't an application, but used by an application on a managed device) like you would with a VPN and have ZTNA security applied to that access.

      EDR should include all NGAV features. The vast majority of EDR/NGAV solutions will detect each other as malicious and cannot be run simultaneously.

    Hi, thanks for the video. I’m working with Cisco ISE and I’m interested about other solutions. How would you compare fortinac with fortinet ztna?

    • @SamuelBarlass
      @SamuelBarlass ปีที่แล้ว

      From a high level: Both are implementations of the Zero Trust principal. FortiNAC protects devices connecting to the network (specifically headless/IoT/OT devices). Fortinet ZTNA is more focused on remote access, and requires an agent (no headless/IoT/OT devices supported). NAC protects network connectivity, ZTNA protects specific applications.

    • @SamuelBarlass

      Cybersecurity is a broad industry, so it's difficult to pinpoint something specific. Many people go after particular degrees or certification as a goal when they are getting started, but keep in mind that understanding the fundamentals of I.T. and how an I.T. organization works are also important. Many cybersecurity professionals started in other I.T. positions and later moved into cybersecurity. If you want to look into certification, CompTIA, Cisco and Fortinet have some great certifications (Some of Fortinet's are completely free).

    • @SamuelBarlass
      @SamuelBarlass ปีที่แล้ว

      IPv6, like many technologies, seems more complex from the outside then it really is. Subnetting in IPv6 is similar to how we've submitted in IPv4, just with Hexadecimal instead of Binary. In fact, since the IPv6 address space is so large, we will likely do much less subnetting (at least in the near future) then we would with IPv4!
