Why Enable DNSSEC?
DNSSEC provides critical security for your domain by preventing DNS-based attacks:
- DNS Spoofing: Prevents attackers from redirecting your traffic to malicious servers
- Cache Poisoning: Protects against DNS cache manipulation attacks
- Man-in-the-Middle: Ensures users connect to your legitimate servers
- Data Integrity: Verifies DNS responses haven't been tampered with
Many security standards, including PCI DSS, recommend or require DNSSEC for domains handling sensitive data. Email security protocols like SPF, DKIM, and DMARC also benefit from DNSSEC protection.
