Conducting awareness training across the organization is the best way to reduce the risk of security incidents from targeted email attacks because it helps to educate and empower the employees to recognize and avoid falling for such attacks. Targeted email attacks, such as phishing, spear phishing, or business email compromise, rely on social engineering techniques to deceive and manipulate the recipients into clicking on malicious links, opening malicious attachments, or disclosing sensitive information. Awareness training can help to raise the level of security culture and behavior among the employees, as well as to provide them with practical tips and best practices to protect themselves and the organization from targeted email attacks. Therefore, conducting awareness training across the organization is the correct answer.
