Watchguard Network Security Practice Test

Which method can be used to reduce the incidence of spam in a corporate email system?

1. Utilize a third-party email verification service.

2. Implement advanced filtering options in the email service.

3. Limit email access to certain hours.

4. Increase user awareness about phishing.

The correct answer is: Implement advanced filtering options in the email service.

Implementing advanced filtering options in the email service is an effective method to reduce the incidence of spam in a corporate email system because it allows for the automatic identification and blocking of unwanted or potentially harmful emails before they reach users' inboxes. Advanced filtering can leverage various techniques, such as analyzing message headers, assessing content characteristics, and applying machine learning algorithms to differentiate between legitimate emails and spam. By fine-tuning these filters, organizations can significantly decrease the volume of spam that users receive, thus enhancing productivity and reducing the potential risk of security breaches that spam can introduce. While utilizing a third-party email verification service can add an additional layer of security, relying solely on this service may not cover all spam emails, as some spam can still bypass such verification processes. Limiting email access to certain hours might improve monitoring but is not a practical or effective method for spam reduction, as it does not address the root cause of spam messages themselves. Increasing user awareness about phishing is valuable for security training, but it does not prevent spam from flooding inboxes. Therefore, implementing advanced filtering options directly targets the issue and effectively reduces spam.
