Firewalls: Guardians of the Digital Age
In today's digital world, where every click and swipe can leave a trail, your online security is paramount. Enter the firewall, the silent sentinel standing guard at the gateway of your network, shielding you from malicious intruders and unwanted traffic.
Imagine a fortified castle, with drawbridges, moats, and vigilant guards. That's essentially what a firewall does for your digital realm. It analyzes incoming and outgoing traffic, allowing only authorized data to pass through while blocking suspicious activity.
Types of Firewalls:
Packet-Filtering Firewalls: These basic gatekeepers examine data packets based on IP addresses, port numbers, and protocols. They're like bouncers checking IDs at the castle gate.
