Understanding Firewalls

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

Types of Firewalls

There are several types of firewalls, including hardware firewalls, software firewalls, and cloud firewalls, each serving different purposes.

How Firewalls Work

Firewalls use predefined rules to allow or block traffic. They can filter traffic based on IP addresses, protocols, and ports.

Benefits of Using a Firewall

Firewalls enhance security by preventing unauthorized access and monitoring network traffic for suspicious activity.

Configuring Firewalls

Proper configuration is essential for effective firewall protection. Regular updates and rule adjustments are necessary to adapt to new threats.
