Early inclusion allows for the identification and remediation of potential vulnerabilities during the design and development phases. This proactive approach strengthens the device's overall security posture before it reaches the market.

How does a medical device security audit address data privacy?

The audit assesses how data is collected, stored, transmitted, and disposed of, emphasizing encryption, strong access controls, and secure data deletion practices. This ensures compliance with regulations like HIPAA and protects patient health information.
