The blight of cybercrimes and data breaches is not leaving anytime soon.
Data breaches in healthcare have increased in both size and prevalence. When we see the last five years’ data, the healthcare industry ranks second as compared to other industries when it comes to data breaches.
In total, about 40 million healthcare records have been exposed so far in 2019 alone.
Why Healthcare Data Hacks are sensitive?
These health data breaches have caused a great deal of concern, especially when the information being exposed is highly sensitive and valuable in nature.
In particular, when loaded with someone’s health information, criminals can commit medical identity theft to see a doctor, get prescription drugs personally, obtain restricted drugs, or file claims under the victim’s name. The impact of health insurance fraud includes financial losses and limited access to healthcare.

Wrapping up – Be aware and encrypt all data using a strong risk-based approach
Where organizations of other sectors should focus more on preventing external hacking, the challenge in the healthcare industry is more internal.
It is, therefore, more important that layers of defense are applied to defend your valuable healthcare data against cyberattacks. Furthermore, the data stored in a file system, moving across an online network or database need to be encrypted and backed up.
Do your research while choosing a framework to protect your data.
