What are firewalls and how do they protect websites?

Firewalls are security systems that monitor and control incoming and outgoing network traffic based on predetermined security rules. They act as a barrier between a trusted internal network and untrusted external networks, helping to protect websites from various threats.

What types of firewalls are there?

There are several types of firewalls, including network firewalls, application firewalls, and next-generation firewalls. Network firewalls filter traffic at the network level, while application firewalls filter traffic at the application level, providing more granular control.

How do I choose the right firewall for my website?

Choosing the right firewall depends on your website's specific needs, such as the type of content you host, the expected traffic volume, and your budget. It's important to assess the level of security you require and consider features like intrusion detection, logging, and ease of management.

Can firewalls prevent DDoS attacks?
