Use DNSSEC DNS Security Extensions (DNSSEC) add a layer of security to your DNS records by enabling cryptographic signatures. This ensures that DNS responses are authentic and have not been tampered with.
Implement SPF, DKIM, and DMARC Utilize SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting & Conformance) protocols to authenticate your emails. These protocols help verify the sender's identity and prevent unauthorized emails from being delivered to your recipients.
Regularly Monitor DNS Records Consistently monitor your DNS records to detect any unauthorized changes. Early detection can help mitigate potential damage from DNS spoofing attacks.
Educate Your Audience Inform your audience about the risks of phishing and educate them on how to identify suspicious emails. This can reduce the likelihood of them falling victim to DNS spoofing attacks.
