With this breach, healthcare organizations globally will need to reassess their cybersecurity posture.

This degree of exposure presents unparalleled implications for healthcare data security, regulatory exposure and public trust in health data handling.

Risk Mitigation

Change Healthcare is said to be collaborating with experts and law enforcement to perform a detailed forensic investigation and to reinforce their system against such threats in the future.

In addition, affected individuals will be offered a credit monitoring service for one year.

Practical Advice: Bolstering Cybersecurity
