The Paradigm Shift: Cybersecurity = Patient Safety

FDA's position is that cybersecurity and patient safety are the same problem: a device whose software can be compromised can't be considered safe and effective. That moves security out of the IT department and into design controls, risk management, and the rest of the product lifecycle, alongside electrical and mechanical safety.

1.4.1 FDA's Clear Position

The FDA has made its position unambiguous. According to the guidance: "As a result, ensuring device safety and effectiveness includes adequate device cybersecurity, as well as its security as part of the larger system."

This represents a fundamental shift in thinking:

• Old view: Cybersecurity is an IT problem
• New reality: Cybersecurity is a patient safety requirement

1.4.2 Why Traditional Safety Thinking Isn't Enough

Medical device manufacturers have always focused on safety. But traditional safety engineering didn't account for intelligent adversaries actively trying to cause harm. Consider the differences:

Traditional Safety Concerns:

• Component failures
• User errors
• Environmental factors
• Manufacturing defects

Cybersecurity Threats Add:

• Malicious actors with intent to harm
• Remote attacks from anywhere in the world
• Attacks that can affect many devices simultaneously
• Threats that evolve and adapt

1.4.3 The Total Product Life Cycle (TPLC) Approach

The Joint Security Plan (JSP) emphasizes that cybersecurity must be considered throughout the entire product lifecycle. This means:

1. Design Phase: Building security in from the start
2. Development: Testing for vulnerabilities during creation
3. Manufacturing: Ensuring secure production and distribution
4. Deployment: Secure installation and configuration
5. Maintenance: Ongoing updates and monitoring
6. Retirement: Secure disposal of devices and data
