1.Provide a brief description of the story.

             June 2018, Fetal Diagnostic Institute of the Pacific was hit by Ransomware attack on personal information some patient records of fetal diagnostic lab breaches but Officials took immediate action to contain the incident and enlisted a cybersecurity firm. They were able to successfully and installed further protections to better prevent future incidents. Backup data server is very important from the situation because of they maintained for contingency and were able to restore the impacted data.

            The situation talked about the weak point of security and privacy as often employees are the weakest links to accessed something or open some email or used other software but it have many way to attack server such as low security and privacy the gab of network system, rack of update operation and software.

Ransomware not designed to steal user information in any way.

Ransomeware targets server store data are financially worth hacking such as credit card numbers, identifiable information. To make the dataset less juicy, the data should be collected only need-to-know data and should be stored with de-identifiable form.
