Organizations can respond to email attacks by developing which of the following?

The development of an acceptable email usage policy is crucial for organizations as it establishes guidelines and rules that govern the appropriate use of email within the organization. This policy serves multiple functions: it educates employees about the risks associated with email, including phishing and malware attacks, and it sets clear expectations for behavior regarding email communication. By defining what constitutes acceptable and unacceptable usage, organizations can effectively reduce their vulnerability to email attacks.

A well-crafted email usage policy can include practices such as identifying suspicious email, reporting protocols for potential threats, and recommendations for maintaining strong passwords. Such policies not only create a culture of awareness among employees but also play a critical role in incident response plans by providing clear steps to follow in case of an email-related incident.

Other options, such as deleting emails from folders or bouncing back emails, might not address the root causes of the issue and can result in uninformed decisions by users. Changing email templates does not inherently improve security; rather, it might just alter the way messages appear without addressing the underlying problem. Thus, a comprehensive policy serves as the foundation for effective email security and incident response within an organization.
