A firewall is like a security guard for your computer or network, deciding which data can come in and go out to keep things safe from hackers and viruses.
Firewalls contribute to network security by acting as a gatekeeper that filters and monitors incoming and outgoing traffic, preventing unauthorized access and protecting against cyber threats.
Different types of firewalls:
1. Packet Filtering Firewall: Checks each packet of data entering or leaving the network based on predefined rules, like source and destination IP addresses, ports, and protocols.
2. Stateful Inspection Firewall: Tracks the state of active connections and monitors incoming packets to ensure they’re legitimate responses to outgoing traffic.
3. Proxy Firewall: Acts as an intermediary between internal and external networks, intercepting and inspecting all incoming and outgoing traffic to enforce security policies.
4. Next-Generation Firewall (NGFW): Combines traditional firewall features with advanced capabilities like application awareness, intrusion prevention, and deep packet inspection.
5. Software Firewall: Runs as software on a computer or server, protecting that specific device from unauthorized access and malicious activity.
6. Hardware Firewall: Dedicated physical devices placed between the internal network and the internet, providing robust protection and higher performance compared to software firewalls.

What is a firewall?
A firewall is a security device available as computer hardware or software. It can help protect your network by acting as an intermediary between your internal network and outside traffic. It monitors attempts to gain access to your operating system and blocks unwanted incoming traffic and unrecognized sources.
How do firewalls work?
A firewall acts as a barrier or gatekeeper between your computer and another network like the internet. It works like a traffic controller, monitoring and filtering traffic that wants to gain access to your operating system.
What does a firewall protect against?
A firewall protects you from unsolicited and unwanted incoming network traffic. It validates access by assessing this incoming traffic for anything malicious like hackers and malware that could infect your computer.
