What Measures Can Be Taken to Prevent Spoofing Attacks?
Preventing spoofing attacks involves a multi-layered approach:
SPF (Sender Policy Framework): This protocol allows domain owners to specify which IP addresses are authorized to send emails on their behalf. DKIM (DomainKeys Identified Mail): DKIM adds a digital signature to each outgoing email, which can be verified by the recipient’s email server to ensure the email hasn’t been tampered with. DMARC (Domain-based Message Authentication, Reporting & Conformance): DMARC builds on SPF and DKIM by providing a way for domain owners to publish policies on how to handle emails that fail authentication checks. User Education: Educating recipients on how to recognize spoofed emails can reduce the effectiveness of these attacks.
