What are some of the steps you recommend to protect Amazon from a 'DOS' attack?

"Denial of Service, or DOS attacks are becoming increasingly prevalent across the Internet. Hackers are using these and ransomware to shut down an organization's operations or request payment to continue to function. I've dealt with many of these types of security threats in my previous roles and am confident I can help your organization prevent these. Methodologies I suggest include educating the workforce about secure passwords and avoiding nefarious websites, setting up VPNs, using robust user authentication, and encrypting data whenever possible. Taken together, these steps will reduce the number of DOS and other security threats Amazon encounters."
