Email Spoofing Detection Using SPF and DNS

Computer Engineering

Email Spoofing is a common technique used by attackers to send malicious emails to victims by disguising their identity as a trusted sender. Spoofing is the act of forging an email sender's address to make it appear as if the email came from a legitimate source. It is a significant threat to businesses and individuals as it can be used to distribute phishing emails, malware, and other harmful content. This paper proposes a solution to detect email spoofing using Sender Policy Framework (SPF) and Domain Name System (DNS). SPF is an email authentication protocol that checks whether the sender's IP address is authorized to send emails on behalf of the domain. DNS is used to publish the SPF records for a domain. This paper discusses the importance of email spoofing detection and the use of SPF and DNS for its detection. The effectiveness of the proposed solution is demonstrated by analyzing the performance of SPF and DNS-based email spoofing detection mechanisms
