What Is Host-Based Firewall?

The term "host-based firewall" might make you think of a person who protects your car's engine by holding back a crowd. But in this case, it's more like a guy who keeps individual parts of your vehicle from getting infected with viruses and malware. Firewalls are a great way to keep your network safe from malicious attacks. They act as gatekeepers between your network and the internet, blocking unwanted traffic and keeping hackers at bay. But what if you want to stop something specific on your computer? What if you want to keep that thing from going out onto the internet and coming back? That's where host-based firewalls come in! When a host-based firewall is enabled, it will block all traffic that doesn't originate from the local machine or device. It means that if you have a laptop with a host-based firewall enabled, only traffic from that laptop will be allowed. If someone tries to send you an email or browse your website, the attempt will fail because the request isn't coming from your machine. Host-based firewalls are also helpful for preventing unauthorized access to your files and resources by limiting what users can see or access on their machines. For example, say you're working on a project with someone who doesn't get along with anyone else—you could install a host-based firewall on their machine so they can't see specific files or folders unless they ask for permission first! You might wonder how this works: you set up rules that tell which traffic is allowed into or out of each host on your network (your home). It's like a firewall for your firewall, but it's more like a second firewall for your first firewall. Host-based firewalls are a great way to double down on security. They're like a standalone device that sits on your computer and keeps out the bad guys lurking in your network. But don't take our word for it.
