This article dives deep into the functions of firewalls, the capabilities of Windows 10’s built-in security features, and whether investing in a third-party firewall is worthwhile.
Understanding Firewalls
A firewall acts as a barrier between your computer (or network) and potential threats that exist on the internet. Its primary function is to monitor and control incoming and outgoing network traffic based on predetermined security rules. By doing so, firewalls can help block unauthorized access and protect your computer from various cyber threats.
Types of Firewalls
Firewalls can be categorized into several types, including:
- Network Firewalls: Typically used in business environments, these firewalls protect entire networks by filtering traffic between internal and external networks.
- Host-Based Firewalls: Installed on individual devices, these firewalls protect specific computers by monitoring traffic to and from those devices.
How Firewalls Work
Firewalls function based on defined security rules. When traffic attempts to enter or leave your computer, the firewall checks it against these rules and decides whether to allow or block the traffic. This way, firewalls can effectively manage application traffic and prevent unauthorized access.
