Healthcare data breaches have become more common and expensive. Reports sent to the U.S. Department of Health and Human Services (HHS) show that the number of data breaches went up from 369 cases in 2018 to 712 in 2022. That is almost twice as many in just four years. Ransomware attacks also grew by 278% during this time. These attacks can interrupt medical services and put patient safety at risk.
More than 80% of healthcare breaches happen because of weak or stolen passwords. This usually occurs through credential theft, phishing, or using the same passwords repeatedly. Microsoft says that turning on MFA blocks 99.9% of automated cyberattacks that use stolen or weak passwords. Because patient information must be kept private, MFA is becoming very important for healthcare security.
The Health Insurance Portability and Accountability Act (HIPAA) does not require MFA, but using it helps meet HIPAA’s rules for controlling access and protecting electronic protected health information (ePHI). Many healthcare groups also use MFA to follow other standards like HITRUST and DirectTrust. They also prepare for audits by groups such as the Centers for Medicare & Medicaid Services (CMS).
Multi-Factor Authentication (MFA) is a security method where users must show two or more ways to prove who they are. These ways come from different categories:
By asking for two or more of these, MFA adds extra protection. This makes it harder for someone to get into systems without permission.
TOTP is a popular MFA method in healthcare. It creates a unique, temporary code using an app on a smartphone. This code lasts for a short time, usually 30 seconds. That means even if someone gets the code, they cannot reuse it later. Apps like Google Authenticator and Microsoft Authenticator do this.
TOTP needs both the user’s password and a physical device to work. For healthcare workers, this means that even if a password is stolen, an attacker cannot get in without the one-time code.
This method sends a one-time code by text message to the user’s phone. While easy to use, SMS codes have risks. Someone might do SIM swapping, take over the phone number, or intercept the messages. Because of these problems, SMS codes are best used along with other methods like biometrics or hardware tokens.
Biometrics check physical traits like fingerprints, face scans, or iris scans to verify who someone is. This method is secure and easy because users do not need to remember passwords or carry extra devices. Some healthcare groups use biometrics to speed up login while keeping things safe.
For example, NorthShore University HealthSystem uses fingerprint and face recognition to make login faster without lowering security.
But biometrics have challenges. They can be costly to set up, raise privacy questions, and need careful storage to protect the biometric data.
Hardware tokens are physical devices that produce codes or act as security keys, like USB devices. Smart cards also store special cryptographic keys and can be used to log in.
These tools are less likely to fall for phishing attacks than password-based MFA. However, they require work to distribute, replace, and keep safe. Healthcare managers must think about how easy they are to use versus the extra work needed to manage them.
The Zero Trust Model (ZTM) is a security idea that is becoming more common in healthcare. It is based on the rule “never trust, always verify.” Under this model, every user, device, or system asking for access is treated as untrusted until it is strictly checked with methods like MFA.
MFA is important here because it provides layers of checks every time someone tries to access a resource. Even after logging in, systems can keep checking based on behavior and risk level.
Security expert Max Edwards from ISMS.online says that combining Zero Trust Architecture with adaptive MFA and dividing networks into small parts helps lower attacks and stops threats from moving around healthcare systems.
Healthcare providers must protect sensitive data to follow many rules:
Using MFA helps healthcare groups reduce risks of breaking these rules, avoid expensive data breaches, and keep patient trust. IBM’s 2023 Cost of a Data Breach report says the average healthcare data breach costs $3.86 million. This can rise to $10.1 million if legal fees, fines, and damage to reputation are added.
There are several difficulties when adding MFA to medical offices and healthcare groups:
Artificial intelligence (AI) is starting to help make MFA safer and healthcare work easier:
AI works with MFA to create a safe system that also helps healthcare workers do their jobs faster. This is important because healthcare workers often have heavy workloads.
Medical managers and IT leaders who want to start using MFA should follow important steps:
Multi-Factor Authentication is an important security tool that healthcare groups in the U.S. need to use to protect patient data. MFA asks users to prove who they are in more than one way—using passwords, hardware tokens, biometrics, or app codes. This limits chances for unauthorized people to get in and helps healthcare follow the law.
New AI and automation tools help make authentication smarter and work easier. Following good plans for MFA will help healthcare leaders keep patient data safe, cut down on costly cyberattacks, and follow all required rules.
Multi-factor authentication (MFA) is a security protocol requiring users to provide two or more forms of authentication to access a system, enhancing security beyond just a username and password.
Types of MFA include Time-based One-Time Passwords (TOTP), SMS codes, push notifications, biometric verification, and smart cards, allowing organizations to select methods based on security needs and user convenience.
MFA enhances security by requiring a user to enter their username and password, followed by an additional form of authentication like a TOTP code or biometric scan.
MFA is crucial in healthcare to protect sensitive data like PII and PHI, reducing the risk of data breaches and ensuring compliance with regulations like HIPAA.
Challenges include usability for non-tech-savvy users, integration with existing systems, costs, increased complexity, and the security of the MFA method itself.
TOTP is a secure MFA method that generates a unique code that expires after a short period, enhancing security by requiring a physical device and a password for authentication.
SMS-based MFA sends a one-time code to a user’s phone but is vulnerable to interception, so it should be used with another authentication factor for better security.
Biometric authentication uses unique physical traits, such as fingerprints or facial recognition, to verify identity, providing a secure form of MFA that’s hard to replicate.
MFA helps organizations comply with data privacy regulations like HIPAA and PCI DSS by adding a layer of security to protect sensitive information.
By integrating MFA with secure content communication channels, organizations ensure that only authenticated users can access and share sensitive data safely.
