Safeguarding personal health information
Health records are intimate, permanent, and extraordinarily valuable to attackers. Protecting them is both an ethical duty and a regulatory one.
Of all the data an organisation holds, personal health information (PHI) is among the most sensitive. You can reissue a credit card; you cannot reissue someone's medical history. That permanence is exactly why PHI commands a premium on criminal markets — and why healthcare providers, insurers, and any organisation handling health data carry a heightened duty of care.
Why PHI is such a target
- It is rich. A single record can contain identity, financial, and clinical data — everything an attacker needs for fraud or extortion.
- It is durable. Unlike a password, a diagnosis or history does not expire.
- It is distributed. PHI flows between clinicians, labs, insurers, and third-party systems — each handoff a potential weak point.
The privacy obligation does not end at your firewall. It follows the data wherever it goes.
Controls that actually move the needle
1. Know where PHI lives
You cannot protect data you cannot locate. Start by mapping where PHI is created, stored, processed, and shared — including shadow IT and third-party services. This data inventory is the foundation of every other control.
2. Enforce least privilege and strong identity
Most breaches involve stolen or misused credentials. Multi-factor authentication, role-based access, and regular access reviews ensure people can only reach the records their job requires.
3. Encrypt — at rest and in transit
Encryption turns a stolen database into unusable noise. It should be the default for PHI everywhere it is stored and every time it moves.
4. Monitor for the unusual
Continuous monitoring catches the warning signs — a clinician account suddenly exporting thousands of records, access from an unexpected location, a new device on the network — before they become a reportable breach.
5. Plan your breach response and reporting
Privacy regimes carry notification obligations with real deadlines. Know in advance who decides, who you must notify, and how — so a stressful day follows a plan rather than improvisation.
Compliance is the floor, not the ceiling. Aligning to privacy law is essential — but the organisations patients trust most go further, treating PHI protection as a core part of the care they provide.
