DNSSEC: What it is, what it isn't, and why your DNS infrastructure needs it

DNSSEC uses cryptographic signatures to ensure the authenticity and integrity of DNS records, protecting against attacks like cache poisoning and man-in-the-middle interceptions. While it does not provide encryption or prevent phishing, it establishes a verifiable chain of trust that links individual domains back to the DNS root. Consequently, it is an essential tool for maintaining secure, compliant, and reliable modern DNS infrastructure.
