Over 94% of cyberattacks originate in the email inbox, with phishing (identity theft) being the main prong of attack. Phishing by means of a “whaling attack”, also known as “CEO fraud” has forced many companies not only to redefine authentication and certification processes, but also to try to prevent the effectiveness of these social engineering attacks at the point of origin: our email inbox.
First step: mail authentication protocols
To effectively minimize the risk, it is advisable to implement a correct configuration of the so-called authentication protocols (SPF, DKIM and DMARC). These protocols verify the legitimacy of the sending servers and to improve the verification of the receipt of e-mails. They therefore serve both to protect us and to improve the protection of others.
To implement them, an audit of their status is carried out.
