How Do Software Firewalls work?
A software firewall is used to run on your computer in the form of a program. They monitor all your network traffic and operate as close to the network interface as possible.
- All of the network traffic will technically reach your system even if you are not using your router. But the firewall prevents malicious traffic. A software firewall prevents the rest of your system exactly like a router from even realizing that there is any malicious traffic.
- In addition, to monitor outgoing traffic, some software firewalls can be configured. A software firewall can warn you and block the attempt when your system becomes infected and some malware attempts to “phone home” by connecting to a known malicious site or tries to infect other systems on your network.
- A software firewall built in and turned on by default in all current versions of Windows. To aware you of the risks, Windows always send you the notification to ensure that the firewall is either turned on (in Control Panel) or not.
How Hardware Firewall Works?
- A router which acts as an intermediate between your computer and internet is truly an outstanding and most cost-effective firewall that most of a computer user can have. It’s generally a bit of hardware that sits physically between your computer and where the wires plug into the wall, with flashing lights that inform you it’s on duty.
- Routers additionally enable you to share an internet connection with the help of NAT (Network Address Translation). NAT “interprets” between the single IP address you’ve been given by your internet service provider, and the IP addresses assigned to your machines by the router.
- The connections that are initiated by your computer are watched by the router. And also it keeps track at the time of establishment of the connection so that when the response returns on that connection, it knows which of your nearby machines gets the information.
- When an outside computer tries to start a connection, the router doesn’t know how which computer to send it this is the one disadvantage. the thing it does is ignore the attempt. That effectively blocks everything on the internet from trying to start a connection to a machine on your local network.
