While technical solutions like antivirus updates, disabling HTML in emails, and web proxy filtering

play significant roles in securing email systems, the best method to prevent email incidents is often

considered to be end-user training. This is because many email threats, such as phishing, rely on

exploiting user behavior rather than technical vulnerabilities. By educating users on the risks

associated with suspicious emails, how to recognize potentially harmful messages, and the

importance of not clicking on unknown links or attachments, organizations can significantly reduce

the risk of email-related incidents. End-user training empowers individuals to act as a critical line of

defense against email-based threats, complementing technical safeguards.

Reference:EC-Council's Certified Incident Handler (ECIH v3) curriculum emphasizes the importance of

a holistic approach to cybersecurity, including the key role of end-user education in preventing email

incidents and other security breaches.
