What Measures Can Be Taken to Prevent Email Spoofing?
There are several measures that businesses can take to protect themselves and their customers from email spoofing:
SPF (Sender Policy Framework): This is a protocol that allows domain owners to specify which mail servers are permitted to send email on behalf of their domain. DKIM (DomainKeys Identified Mail): This adds a digital signature to outgoing emails, verifying that they haven't been altered in transit. DMARC (Domain-based Message Authentication, Reporting & Conformance): This builds on SPF and DKIM to provide a way for domain owners to specify how email from their domain should be handled if it fails authentication checks.
