This summary captures the heart of an effective security program, especially your emphasis on training and multi-factor authentication. Absolutely, employees are the first line of defense, and continuous training helps in minimizing human error, one of the major causes of data breach. I would like to add that a Backup and Recovery Policy is also crucial. While protective measures can be put in place, there is always a risk for ransomware attacks and a proper backup strategy to quickly restore critical data without giving in to the attackers or losing fundamental information.
