Firewalls have become a standard tool for Internet security. A firewall, for example, is incorporated into your home Wi-Fi router and can also be used by your computer.
But how did a rather uninteresting technology acquire such a fantastic name? Why is it called a firewall, anyway?
The name is stolen from the building industry
Firewalls (literal translation of “wall of fire”) have been around for a long time, far longer than the Internet has existed. However, firewalls didn’t originate from the IT business. The first firewalls can be found in the construction industry, where they are an important security design feature.
A firewall is a specially reinforced fire barrier that is used to limit or stop the spread of fire in construction. Firewalls are generally constructed of concrete and may endure temperatures up to +400°C.
The firewall will slow or halt the fire’s spread if it catches on fire. This helps to minimize harm to the remainder of the structure and gives individuals more time to flee or exit the area.
Computer firewalls are similar to building firewalls
Firewalls, on the other hand, are designed to prevent hackers and harmful web traffic from entering your personal network. The firewall acts as a barrier by keeping hackers and malevolent website traffic out of your home network.
Smarter than concrete
A concrete firewall, on the other hand, is a simple fireproof barrier. Because it can monitor traffic flowing into and out of your network, a computer firewall is considerably “smarter.” Every single piece of data that goes through the firewall is meticulously examined to assure that it is “safe.”
Your firewall will instantly detect and prevent harmful activity, keeping online criminals at bay. Simultaneously, “safe” traffic is permitted both toward and away from your network when it enters the Internet.
A computer firewall, like a concrete one, can resist assaults for hours or longer.
An important aspect of your personal security
Your home Wi-Fi router’s firewall already provides some protection for your network. What if you and your computer are not at home?
When you’re on the road, protecting your laptop with a firewall is the same as if you were at home. The firewall incorporated into your antivirus protects you against harmful traffic and hackers when you connect to a public Wi-Fi network or any other untrustworthy network.
If your computer has no firewall, it is at risk of being hacked by hackers.The firewall protects you from active hacking tools, but antivirus software cannot. Viruses, Trojans, and worms can all be handled by malware protection programs; however, the firewall defends against active hacking methods.
