Today’s security technologies use different techniques for allowing traffic flows through the network. In this video, you’ll learn about firewall-based stateful inspection and how to perform simple packet filtering in other network devices.
Our firewalls allow us to keep the bad guys away from our systems but still provide for connectivity to network resources. In this video, you’ll learn about the advantages and disadvantages of hardware-based firewalls and software-based firewalls.
Firewalls are one of the most fundamental security components in our modern networks, but not all firewalls are created equally. In this module, you’ll learn about common features of modern firewalls, such as network-layer and application-layer firewalls, stateful vs. stateless operation, content filtering, signature identification, and zone-based security.
