Hello friends, in this article we will be learning about the usage of security devices in Organizations and colleges/universities.
The reason they use a firewall is to protect their data and to keep an eye on the traffic of their network.

Uses of firewall
- a firewall is used for authentication purpose
- a firewall is used for application blocker/sites or URL blocker
- a firewall is used for blocking port numbers
- a firewall is used for monitoring incoming and outgoing network traffic.
Authentication Purpose
You might have come across this while you were in your college or while working, to gain internet access you first have to log-in with the credentials provided to you after successfully logging in you would get internet access.

Application blocker
In your working area/network, you might have noticed some of the application is blocked and you cannot use them until or unless connected through a proxy, this is because IT admins have blocked the particular program on the firewall.

This is a feature which allows us to block a website/URL, this feature is also found in antivirus software where we can block a specific URL (example- Facebook, porn sites)

This is the feature using which we can block specific port numbers or protocols, if we don't block unwanted ports there's a chance that our computer gets hacked. Hackers attack our computer with the help of ports, so to prevent our system/network IT admins block ports.

Monitoring Network Traffic
In an organization, this feature is used to find what kind of traffic is consuming more bandwidth on the network and who are trying to connect to an internal/private network.
