How are firewalls placed in the network architecture?

There are two major types of firewalls: hardware-based and virtual-private network (VPN) appliances. The former operates as a physical barrier between the Internet and your network, while the latter operates as a single point of security throughout a LAN or a WAN. When you're designing your network, you can put either type of firewall in your architecture. However, many companies implement physical firewalls to protect their business from attacks coming from the Internet, such as botnets and malware. Most networks contain both types of devices, but there are some exceptions which are also covered in our PSE Strata Dumps. For example, if you're using Layer 3 switching for your network that is, routing data packets based on the contents of the packet then you don't need firewalls because they're unnecessary. Most firewalls operate at Layer 2 (data link layer). They block traffic based on whether it's destined for the outside world (Internet) or coming from the inside to an internal LAN or WAN segment. You can also use access lists to control traffic between VLANs or subnets separated by a firewall.
