CyberGuard Tips

Almost every scam starts the same way: you click something, and your device looks up a domain name. Before a single byte of the fake login page loads, your device asks a DNS resolver, "what is the IP address for this domain?" If that resolver simply refuses to answer for known phishing and malware domains, the attack ends there — no antivirus scan, no warning banner, nothing to click through. That is what encrypted, filtered DNS gives you. It is one of the highest-impact security changes an ordinary household can make, it is free, and it takes about ten minutes to set up across every device in the home. What DNS Actually Does DNS, the Domain Name System, is the phone book of the internet. Humans use names like example.com; the network routes on numbers like 93.184.216.34. Every app on every device performs dozens of these lookups per minute. By default, those lookups go to whatever resolver your internet provider assigned when your router connected. That has two conse...

  Every device in your home — laptops, phones, TVs, cameras, thermostats, game consoles — passes its traffic through one box. Compromise that box and an attacker sits between you and the entire internet, able to redirect your banking site, watch your traffic, and reach devices you assumed were private. Yet the typical home router runs on factory settings from the day it was plugged in. Here are the ten changes that matter most, roughly in order of impact. Do the admin password change last, not first. On the router I set up, every settings change logged me straight back out afterwards, so changing credentials at the start meant re-authenticating after each of the following nine steps. Before You Start: Get Into Your Router Open a browser and go to your router's admin address — usually 192.168.1.1 or 192.168.0.1 . The default login is often printed on a sticker on the router itself. Many modern routers are managed through a phone app instead, which works just as well. 1. Ch...

Why Smart Home Security Matters More Than Ever in 2026 By 2026, the average American home contains more than 25 connected devices — from smart speakers and thermostats to security cameras and baby monitors. While these devices add convenience, each one is a potential entry point for hackers. A compromised smart home device can give cybercriminals access to your personal data, your home network, and even your physical security. The good news? Securing your smart home doesn't require an IT degree. This guide walks you through every step — from securing your router to managing device firmware — so you can enjoy the benefits of a connected home without the risks. Understanding IoT Security Risks Before diving into solutions, it helps to understand what you're protecting against. Smart home devices (also called IoT devices — Internet of Things) face several unique security challenges: Weak default credentials: Many devices ship with username "admin" and passwo...
