What is a firewall and why is it important for network security?

A firewall is a security device that monitors and controls incoming and outgoing network traffic based on predetermined security rules. It's crucial for protecting networks from unauthorized access and cyber threats.

How do firewalls differ from antivirus software?

Firewalls primarily focus on controlling network traffic, while antivirus software detects and removes malware from devices. Both are essential for comprehensive security.

Can you explain the different types of firewalls?

Sure! There are several types of firewalls, including packet-filtering firewalls, stateful inspection firewalls, proxy firewalls, and next-generation firewalls, each serving different security needs.

What are some common firewall configurations?

Common configurations include setting rules for allowed and blocked IP addresses, defining port access, and implementing VPN support for secure remote access.

How can I choose the right firewall for my business?

Consider factors like the size of your network, the types of data you handle, your budget, and whether you need additional features like intrusion detection or VPN support.
