Understanding Secure Network Architecture Design | TryHackMe

In this video walk-through, we covered secure network architecture design concepts such as VLANs, security zones, access control lists, DNS snooping and ARP inspection.  VLANs are used to separate computers and devices into logical compartments for effective implementation of traffic control and security. VLANs are divided into security zones such as trusted, DMZ and zero trust zones. ACLs control traffic flow by writing rules in the firewall that permit/drop packets based on source/destination IP/port. This was part of TryHackMe Secure Network Architecture.
