Firewall Software
A firewall is software that helps protect your computer from unauthorised access. It does this by blocking incoming connections that you do not authorise. A firewall can also block outgoing connections that you do not authorise.
Firewall software is designed to work with the operating system of your computer. Installing a firewall will create a list of rules that determine what kinds of traffic are allowed through and what kinds are blocked. You can usually customise these rules to better suit your needs.
There are different types of firewalls, including hardware-based and software-based firewalls. Hardware-based firewalls are physical devices installed between your computer and the internet connection. Software-based firewalls are programs that run on your computer and use the resources of your operating system to filter traffic.
Both hardware-based and software-based firewalls have their advantages and disadvantages. Hardware-based firewalls tend to be more expensive, but they can provide a higher level of security since they are dedicated devices that do nothing but firewall duties. Software-based firewalls tend to be less expensive but rely on your computer’s resources, which can impact performance if the firewall program is not well-optimised.
The best way to protect your computer is to use a hardware- and a software-based firewall. This process will give you the most comprehensive protection against unauthorised access.
