Where this comes up

This sits inside the security risk analysis under 45 CFR 164.308(a)(1)(ii)(A) — workstation controls, EHR access roles, ePHI transmission encryption, audit logging, vendor risk, and incident response. Reviewers expect dated evidence of the control, not a policy PDF that says it exists.

Full definition

What it is in practice

Phishing is the most common initial-access vector in healthcare breaches reported to OCR. NIST SP 800-66 Rev. 2 recommends recurring security-awareness training and simulated phishing as part of the 45 CFR 164.308(a)(5) awareness program.

How it shows up in your practice

Combine MFA, email authentication (SPF/DKIM/DMARC), and monthly simulated phishing. Track click rates and target retraining at repeat clickers.
