What is a Firewall?

A firewall acts as a barrier between a trusted internal network and untrusted external networks. It helps prevent unauthorized access and threats.

Types of Firewalls

There are several types of firewalls, including hardware firewalls, software firewalls, and cloud firewalls.

Hardware Firewalls

These are physical devices that protect the network by filtering traffic based on predetermined security rules.

Software Firewalls

Software firewalls are installed on individual computers and monitor traffic to and from that device.

Benefits of Using a Firewall

Firewalls provide essential protection against cyber threats, helping to secure sensitive data and maintain privacy.
