Network Firewall Explanation
Firewall is a computer network security system that is able to protect computers from various attacks on the internet.
Its main task is to monitor and control all access in and out of network connections based on predefined security rules. In other words, a firewall is a wall or partition that limits between our computers and the internet network.
That was the definition of a firewall and its function in brief. Watch until the end to find out more about firewall functions.
Functions Of Network Firewalls
There are many features of a firewall that you can use to stay safe while surfing the internet. Here are some functions that are important for you to know:
Protect Data from Hacker Attacks
If you surf the internet a lot and never control your internet network. Then the more likely you are exposed to a cyber attack. To avoid this, you need to activate a firewall protection system to stay safe surfing the internet.
Able to Block Unwanted Content
Firewalls can also be used to block unwanted content. You can control what content is accessible and not via a computer.
For Bandwidth Monitoring
Apart from ensuring your internet network is secure, a firewall can also be used to monitor and limit the bandwidth used by the network.
Can Access VPN Service
Can access VPN services, the firewall also has a VPN (Virtual Private Network) feature that has the function to access your internal network. You also have access to open websites or content that is blocked by certain parties.
How Network Firewalls Work
A firewall is a security system on a computer and how it works is related to security itself. The workings of the firewall are as follows:
Perform Package Filtering
The firewall will filter any data or files that enter the computer. The filtered data will be forwarded to the requested system and unused data will be discarded.
The firewall will retrieve information on the internet which will then be sent to the requested system. The proxy application in the firewall is responsible for checking packets on the network.
Carry out Stateful Inspections
The firewall will track the received packets. Received packets will be checked in the packet database. If the packet does not represent a hazard, it will be forwarded to the requesting system.
After the firewall has finished checking, it will then respond in one of three ways:
- Accept, meaning that the firewall gives access to traffic to pass through the network.
- Reject, meaning that the firewall does not allow traffic to pass through the network and will respond by displaying an “unreachable error”.
- Drop, meaning that the firewall refuses traffic to pass through the network without giving any response.
