Network Firewall vs. Host-based Firewall

Network firewall and host-based firewall are both essential components of a robust cybersecurity strategy. Here's a simplified explanation of the differences between the two:

Network Firewall:

A network firewall is a perimeter security device that monitors and controls incoming and outgoing network traffic based on predetermined security rules. It acts as a barrier between a trusted internal network and untrusted external networks, such as the internet. Network firewalls can be hardware or software-based and are typically deployed at the network boundary.

Host-based Firewall:

A host-based firewall, on the other hand, is a software application installed on individual devices or hosts to monitor and filter network traffic on that specific device. It provides an additional layer of defense by enforcing security policies at the endpoint level, protecting against threats that may bypass network-level defenses. Host-based firewalls are especially valuable for securing user endpoints like laptops, desktops, and servers.

In summary, while network firewalls protect the entire network infrastructure, host-based firewalls focus on securing individual devices. Organizations often employ both types of firewalls in a multilayered defense strategy to mitigate various cyber threats effectively.
