To make precision medicine a reality and tailor a person’s healthcare based on their genetics, we need to access large quantities of clinical and genomic data across borders. But such a far-reaching effort creates many security challenges. Cyberattackers already regularly target healthcare data. The Data Security Work Stream develops standards to ensure individual privacy, data confidentiality and integrity, and service availability, especially within and between GA4GH tools.
Please report potential security flaws in GA4GH standards to security-notification [at] ga4gh.org.
Data Security is a foundational Work Stream, which means it formally reviews all GA4GH products during the approval process.
