What are Domain Name System Security Extensions (DNSSEC), and how can you implement DNSSEC in Amazon Route 53?
DNSSEC is a security protocol that adds an additional layer of protection to the Domain Name System (DNS) by validating DNS responses using digital signatures. It prevents attackers from manipulating or forging DNS data, ensuring the integrity and authenticity of the information.
To implement DNSSEC in Amazon Route 53, follow these steps :
1. Enable DNSSEC signing for your hosted zone in Route 53.
2. Create a Key Signing Key (KSK) and Zone Signing Key (ZSK) pair for your domain.
3. Configure your domain’s DNS records with the generated keys.
4. Sign your zone file using the ZSK and KSK pairs.
5. Publish the signed zone file to Route 53.
6. Update your domain registrar with the Delegation Signer (DS) record containing the KSK public key hash.
Note that not all top-level domains support DNSSEC, and some registrars may require manual configuration.
