What is a firewall?
Watch now. A firewall is a network security device that monitors incoming and outgoing network traffic and decides whether to allow or block specific traffic based on a defined set of security rules. Firewalls have been a first line of defense in network security for over 25 years.
What are ports in a firewall?
Firewalls guard traffic at a computer’s entry point, called ports, which is where information is exchanged with external devices. For example, “Source address 172.18.1.1 is allowed to reach destination 172.18.2.1 over port 22.". Think of IP addresses as houses, and port numbers as rooms within the house.
What is a firewall in LAN?
The firewall is the barrier between a trusted and untrusted network, often used between your LAN and WAN. It's typically placed in the forwarding path so that all packets have to be checked by the firewall, where we can drop or permit them. Here's an example: Above we have our LAN that has a host computer and a switch.

How does a firewall work?
These firewalls include all the capabilities of a traditional NGFW and also provide advanced threat detection and remediation. With a threat-focused NGFW you can: 1 Know which assets are most at risk with complete context awareness 2 Quickly react to attacks with intelligent security automation that sets policies and hardens your defenses dynamically 3 Better detect evasive or suspicious activity with network and endpoint event correlation 4 Greatly decrease the time from detection to cleanup with retrospective security that continuously monitors for suspicious activity and behavior even after initial inspection 5 Ease administration and reduce complexity with unified policies that protect across the entire attack continuum
What is proxy firewall?
