You, the owner of your network, can access any port a visitor can only access some of them – or none of them if the firewall prevents it. After that, the firewall provides more filters so that only certain traffic sources can access those ports. Only certain source addresses can get through the IP address in the first place. For our purposes, the IP address is what houses the ports – your network ports sort of live within the IP address. This is where data flows between external and internal devices – and it’s a vulnerable spot for your network.Īn Internet Protocol (IP) address is a unique address given to a device or network. Malware: Attackers who want to infect your device or server with malware, which can steal your personal information, harm your computer and even spread to other devices.Ī firewall will act as a data guard at your computer’s entry point, called the port.Intrusions: Unauthorized users who try to access your computer or server.DDoS Attacks: An attack that sends thousands (or even millions) of fake packets to cause server overload and take your site down.

Brute Force Attacks: Hackers who try hundreds of username and password combos to discover your login credentials.There are pre-set rules to analyze and filter traffic, rerouting data that comes from suspicious or unsecured sources in order to prevent attacks on your network.įirewalls protect your website against the following: This blocks hackers, viruses and other malicious traffic.

Its purpose is to create a barrier between your internal network and traffic that flows in from external sources – like the rest of the internet. It monitors network traffic – both incoming and outgoing – to either allow or block data packets based on its security rules. To revisit, it’s a device used for network security. And from the web server’s point of view, it needs protection between itself and the thousands of connections it makes with computers every day. The same goes for connecting to a web server. You wouldn’t connect to another device – like a stranger’s computer or iPhone – without some sort of protection in between, right? If you did, you’d worry that they could steal your information or somehow attack your device. And since servers are, essentially, computers, they’re vulnerable to the same types of attacks that your personal computer is. Whenever you use your computer to visit a website, you’re connecting to another type of computer: a web server. It provides protection between the computer and…well, everything else. In its simplest terms, a firewall is like a virtual bouncer. How are hackers and malicious traffic kept at bay whether you’re protecting a computer, network or server? With firewalls. Otherwise, they’re especially vulnerable to an attack. But in addition to your computer, online servers also need protecting. You already know that your computer needs protection, and you’re likely doing what you can to keep it safe (we hope).
