What are the two main types of firewalls?

The two main types of firewalls are network firewalls and host-based firewalls. Network firewalls are typically positioned at the boundary of a network and are responsible for monitoring and controlling incoming and outgoing traffic based on predefined security rules. They act as a barrier between trusted internal networks and untrusted external networks, protecting the entire network as a whole.

Host-based firewalls, on the other hand, are installed on individual devices or hosts within a network. They monitor and control the network traffic to and from that specific device, providing a layer of protection that is tailored to the individual user's needs. This type of firewall is beneficial for protecting devices from threats that may originate from the local environment or network.

Both types serve essential roles in cybersecurity, addressing different aspects of network security and ensuring robust protection against a variety of cyber threats.
