DNSSEC Details

DNSSEC (Domain Name System Security Extensions) is a set of security extensions for the Domain Name System (DNS) that is designed to protect the DNS infrastructure from various types of attacks.

Key Features

• Integrity: Protects against DNS data tampering and modification.
• Non-repudiation: Prevents the sender from denying that they sent a message.

Implementation Steps

1. Sign your DNS zone: Use DNSSEC tools to sign your DNS zone.
2. Publish the public keys: Publish the public keys in the DNS zone.
3. Configure your DNS resolver: Ensure your DNS resolver is configured to validate DNSSEC signatures.
