Your home network connects dozens of devices — computers, phones, smart TVs, cameras, and IoT gadgets. Each one is a potential entry point for attackers. Here's how to lock it down without a computer science degree.

Step 1: Secure Your Router

Change the default admin password (the one on the sticker) to something unique. Update the firmware — most routers have a "check for updates" button in settings. Enable WPA3 encryption (or WPA2 if WPA3 isn't available).

Step 2: Create a Guest Network

Put IoT devices (smart speakers, cameras, thermostats) on a separate guest network. If a smart lightbulb gets compromised, attackers can't reach your computer.

Step 3: Enable DNS Filtering

Set your router's DNS to Cloudflare's malware-blocking service (1.1.1.2) or Quad9 (9.9.9.9). This blocks known malicious domains automatically.

Step 4: Keep Everything Updated
