DNS was built for speed, not security. That's why attacks like spoofing, cache poisoning, and hijacking are still common. Here are the practices that actually protect you.
Why DNS Security Matters
Every action on the internet starts with a DNS query. When you visit a website, send an email, or open an app, your device first asks a DNS resolver to translate a domain name into an IP address. If that process is compromised, an attacker can redirect you anywhere — and you'd never know.
The DNS protocol was designed in the 1980s when the internet was a trusted academic network. It has no built-in authentication, no encryption, and no way to verify that the answers you receive are legitimate. That's why DNS attacks remain one of the most effective tools in an attacker's toolkit.
Some important things to note down for dns security
- Enable DNSSEC
- Use Encrypted DNS (DoH or DoT)
- Choose a Secure DNS Resolver
- Secure Your Email with DNS Records
- Lock Your Domain and Monitor Changes
