🔥 Network Security: Firewalls
A firewall is like a protective wall between your network and the internet. It checks all traffic that tries to enter your network and blocks anything that looks suspicious. Imagine it's a vigilant guard who checks everyone who tries to enter your home and doesn't let in those who don't have the right.
Firewalls can be hardware or software.
Hardware firewalls are separate devices that connect to your network.
Software firewalls are programs that are installed on your computer.
Firewalls are an important tool for protecting your network from hackers and malware. They help prevent unauthorized access to your information and protect your data from theft.

Behind it is a network of swirling data and vibrant colors that represent the flow of digital information. This barrier is designed to block out all unwanted traffic represented by shadowy, dark tendrils trying to penetrate the wall. In a 3d digital art style, in a high-resolution, with a wide-angle lens, showing all the details and the composition of data and the filter.
