Firewalls are designed to shield and protect our trusted networks from the untrusted. • • The idea is that a firewall will block all the bad traffic from the attackers. • While at the same time, allow normal flow for the good traffic. • • Most firewall, by default, block everything! • • It doesn't matter if its traffic leaving the network or traffic entering the network. Everything is blocked. • • The way we allow traffic to pass the firewall without being block is by adding firewall rules. • Next-gen firewalls take the same methods but then enhances them with more in-depth security features. • • Generally speaking, this is what a next-generation firewall should include. • • Application Level Inspection: So the firewall can identify and block risky application traffic. • • Intrusion Prevention Systems or IPS: IPS will inspect the contents of the traffic and look for patterns or signatures of malicious or malware related traffic. • • External Threat Intelligence: Next-generation firewalls can update themselves from external threat intelligence sources. • • Computers can also have software-based firewalls. For example, the windows firewall is built-in and uses the same rule-based methods. Such as port, destination, and source IP addresses. • • Having a firewall both on the network and the endpoints is important when creating a layer security posture. • #ccna #cisco #networking
