What are the three types of firewalls?

The three types of firewalls are hardware-based, software-based, and cloud-based firewalls. Hardware firewalls are physical devices that protect a network, while software firewalls are programs installed on individual devices. Cloud firewalls are managed by third-party providers and protect network traffic in the cloud.

Here's a more detailed explanation:
Hardware-based firewalls:
These are physical devices that sit between a network and the outside world, acting as a gatekeeper for network traffic. They are often used to protect entire networks, like those in businesses or organizations.

Software-based firewalls:
These firewalls are installed directly on a computer or server and protect that individual device. They are often used for personal computers or individual servers.

Cloud-based firewalls:
Also known as Firewall-as-a-Service (FWaaS), these firewalls are managed by a third-party provider and protect traffic in the cloud. They are often used by organizations that have a significant online presence or use cloud-based services.
