Cybercriminals often employ forged emails to deceive both your customers and employees into revealing their login credentials. They may also send counterfeit invoices to your business partners and suppliers, creating further chaos. Additionally, these malicious actors distribute harmful emails that contain malware, such as ransomware, which can severely impact your organization. Furthermore, they utilize email spoofing techniques to sell illicit products, including weapons and drugs, while masquerading as reputable brands. To combat these threats, DMARC serves as an email validation protocol that hinges on two widely recognized authentication methods, SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail). SPF functions by allowing the recipient's mail server to verify whether the email sender's server is permitted to dispatch emails on behalf of the organization, thereby enhancing security. Meanwhile, DKIM employs a cryptographic method that utilizes both public and private keys to authenticate messages, ensuring their integrity during transmission from sender to recipient mail servers. Implementing these protocols is crucial in safeguarding against email-based attacks.
