Creating a wall between your internal network and the outside world—which could include the internet—is one of the main functions of firewalls. Firewalls serve as a shield in this way, stopping unwanted access to private information and network resources.

2. Monitoring Network Traffic
Based on predefined security criteria, firewalls actively monitor all incoming and outgoing network traffic. They are able to recognize and report any questionable or potentially dangerous activities, such illegal attempts to get access to your network, thanks to this ongoing observation.

3. Packet Filtering
Data packets are inspected by firewalls using packet filtering while they are traveling over the network. Analyzing the source and destination addresses, port numbers, and protocol in use is required for this. Firewalls can decide whether to accept or deny the packets based on a thorough examination of these details.

4. Stateful Inspection
Stateful inspection, also known as dynamic packet filtering, differs from classical packet filtering in that it considers the current state of active connections. By keeping track of the current state of active connections in a table and making judgments depending on the traffic context, stateful inspection firewalls improve the accuracy of recognizing allowed and valid communications.

5. Application Layer Filtering
In the OSI model, firewalls can function at the application layer, which enables them to filter traffic according to particular services or applications. More precise control over the kinds of activities allowed on the network is made possible by this, improving security by limiting access to potentially vulnerable applications.

6. Protection Against Cyber Threats
First line of security against a range of cyberthreats, such as viruses, malware, and other malicious activity, is a firewall. Firewalls play a major role in preventing cyberattacks by preventing unauthorized access and removing potentially hazardous content.

7. VPN (Virtual Private Network) Security
Firewalls are essential for guaranteeing the security of connections made by enterprises using VPNs to create safe online connections. To stop illegal access and protect the privacy of the data being sent, they monitor and regulate VPN traffic.

8. Logging and Reporting
Network activity logs are kept up to date by firewalls, giving administrators important information about possible security incidents. By identifying patterns, anomalies, or suspicious behavior, these logs can be examined and analyzed to help uncover security issues early on.

9. Intrusion Detection and Prevention
Certain sophisticated firewalls provide features for preventing and detecting intrusions. These capabilities give firewalls an extra line of defense against online attacks by allowing them to recognize and react to questionable activity in real time.

10. User and Content Filtering
