Forging email headers to make messages appear from trusted sources.
Email spoofing is the creation of email with forged sender addresses, making messages appear to come from trusted sources—your CEO, your bank, or your IT department. Spoofing exploits the inherent trust in email 'From' addresses. Without authentication (SPF, DKIM, DMARC), anyone can send email appearing to be from any address. Spoofing enables phishing, BEC, and fraud. Implementing DMARC with enforcement protects your domain from being spoofed.
Why It Matters
The DSC Perspective:
Your domain can be spoofed for attacks against your customers, partners, and employees. Implement DMARC to protect your domain reputation and prevent attackers from impersonating your organisation.
