DNS Security
Why DNS Matters
DNS is the foundation of how we navigate the Internet — and one of its most exploited weak points.
What Is DNS Security?
The Domain Name System (DNS) acts like the Internet's address book — translating domain names (like hafnova.com) into machine-readable IP addresses. Without DNS, accesing online services would be like navigating with raw GPS coordinates.
It is seamless for users, but this invisibility also makes DNS a prime target for cybercriminals.
Attack Surface
DNS Cyberattacks Explained
DNS is a critical attack surface. Cyber attackers exploit it to:
Phishing & Spoofing
Redirect users to fake websites impersonating trusted brands.
DNS Tunneling
Exfiltrate sensitive data covertly through DNS queries.
DDoS Amplification
Overwhelm targets with massive traffic through DNS amplification.
C2 Communications
Hide malware command-and-control channels inside DNS traffic.
MITM & Cache Poisoning
Hijack traffic by corrupting DNS caches or intercepting queries.
DNS is too often overlooked by traditional security tools. It's a blind spot attackers know and use.
