Why Healthcare Organizations Are Targeted

Sensitive Patient Data
Electronic health records (EHRs), insurance details, and personal health information (PHI) are highly valuable on the dark web — making healthcare systems prime targets.

Complex, Interconnected Systems
Hospitals and clinics rely on multiple access points — staff accounts, third-party vendors, outdated devices — increasing exposure to compromise.

Key Strategies to Prevent Unauthorized Access

1. Strengthen Identity Controls
   Use Conditional Access, MFA, and Privileged Identity Management (PIM) to restrict high-risk access.

2. Encrypt and Classify Patient Data
   Apply Microsoft Purview sensitivity labels and encryption policies to protect data at rest and in transit.

3. Monitor User Behavior and Access Logs
   Leverage Microsoft Sentinel to detect unusual logins, lateral movement, or data exfiltration attempts.

4. Secure Workloads and VMs
   Use Defender for Cloud to enforce security recommendations across hybrid and cloud workloads.

Protecting Patient Trust

1. Limit Access to Health Records
   Apply role-based access controls (RBAC) to ensure only authorized staff can view sensitive records.

2. Train Clinical and Administrative Staff
   Regularly educate staff to recognize phishing attacks and insider threats.

3. Screen Third-Party Vendors
   Conduct risk assessments for any external systems accessing your network or patient data.

Responding to a Breach

1. Investigate with Copilot in Azure
   Use natural language prompts to quickly summarize incidents and generate KQL queries in Microsoft Sentinel.

2. Alert Patients and Comply with HIPAA
   Quickly notify impacted individuals and meet federal breach notification requirements.

3. Apply Lessons Learned
   Refine incident response playbooks and implement new prevention controls.
