What is DNSSEC?

DNSSEC (Domain Name System Security Extensions) is a set of protocols that add security and authentication to the Domain Name System (DNS). It ensures data integrity and prevents DNS spoofing by digitally signing DNS records.

Key Features

  • 🔒 Data Integrity: Verifies that DNS data has not been altered.
  • 📜 Authentication: Confirms the authenticity of DNS responses.
  • 🌐 Prevents Spoofing: Blocks malicious attempts to redirect users to fake websites.

Core Concepts

  1. DNSSEC Zones: Zones that are signed using cryptographic keys.
  2. DNSKEY Records: Public keys used to verify DNS data.
  3. DS Records: Trust anchors that link parent and child zones.
  4. RRSIG Records: Digital signatures for DNS resource records.
