ImportantĪll sites hosted on Kinsta are automatically protected by our free Cloudflare integration, which includes a secure firewall and DDoS protection. Nowadays they’ve evolved into complex pieces of programming that are much better at keeping out-attempted intrusions and are an essential piece of software for all devices. When they were first developed, firewalls were very simple packet analyzers that allowed or blocked incoming traffic based on a minimal set of predefined rules. It’s a big filtration system for your computer or server. Should it detect something suspicious, it will instantly block it from reaching its destination. Connecting to a web serverįirewalls simply monitor incoming and outgoing traffic on a device, scanning for any signs of malicious activity. It’s the intermediary between you and any other devices trying to connect to you or, in a web server’s case, between it and the hundreds or thousands of connections it makes with others every day. Once that connection is established, it’s much easier to infect the other party with malware or launch a DDoS attack. It’s not safe to connect so directly to another device without any kind of protection in between. Whenever you visit a website, you’re basically connecting to another computer: the web server. But because a server is just a specialized kind of computer, it’s susceptible to the same kind of attacks your own PC is. What Is a Firewall? What Does a Firewall Do?
