Introduction to Zero-Trust in Healthcare
Although the healthcare industry is constantly at risk for cyberattacks, it’s also important to be aware that some of these attacks are internal [1]. For instance, healthcare employees may intentionally, or unintentionally compromise the security of their healthcare network. This can range from not properly storing their passwords to even clicking on harmful links or emails that may seem harmless. Furthermore, providers often have access to sensitive patient data ranging from a patient’s medical history to their social security number. This is where a zero-trust model comes in, which promotes complete network visibility.
Zero-trust is a decision where devices and users are not trusted, resulting in them being verified before they can access data and systems [2]. This means that doctors will need to be authenticated before accessing labs, other doctors, or even other applications [2]. Furthermore, zero-trust often comes with multifactor authentication, which can be useful when a user logs in from different IP addresses or locations [2]. In general, zero-trust protects sensitive patient data by authenticating every access request. However, oftentimes a one-size-fits-all approach to zero-trust is implemented, which can lead to inefficiencies in care. This is where HCD comes in, which accommodates the varying levels of security required in different areas and scenarios. HCD promotes a dynamic approach to zero-trust, while still maintaining effective protection of sensitive patient data.
User Authentication Within and Outside Boundaries
When discussing zero trust models, it’s important to discuss that oftentimes healthcare providers may switch between working remotely to working within the facility’s boundaries. When shifting away from a one-size-fits-all approach, it’s important to consider the different levels of security that are required when an employee is working remotely versus onsite. For instance, when an employee is onsite, they may only need to be authenticated once to access the facility’s network. However, they must still be continuously monitored in the background to ensure that their access is not left unchecked. This means that their behaviors and requests for access align with expected patterns and any deviations trigger reauthentication. This promotes a smooth and secure operation.
Alternatively, if a user is outside of the facility’s boundaries, then the zero trust model should be adopted to become stricter. For instance, the user may be required to go through a multi-factor authentication process. Oftentimes, this authentication process checks the user’s location, as well as multiple combinations of security measures to verify the user’s identity and access request. This ensures that only authorized users access sensitive data remotely.
HCD Overcomes Limitations of a One-Size-Fits-All Approach
When zero-trust is adopted with a one-size-fits-all approach, it can lead to ineffective healthcare solutions that can delay care for patients and complicate workflows for providers. However, HCD can reduce inefficiencies, primarily by working with stakeholders to consider their needs. For instance, small clinics might need increased streamlines with less intrusive security measures when compared with a more complex and larger hospital that might have a higher risk. HCD requires health IT companies to obtain the specific needs of the facility so that a flexible zero-trust model can be adopted that adjusts security policies to align with the unique operation and security requirements of each facility. This promotes practical usability while protecting sensitive patient data.
Furthermore, a one-size-fits-all will not address the needs of healthcare providers who may switch from being in-person to working remotely. Therefore, it’s important to consider the different levels of security required for workers who stay in one location, versus workers who switch locations throughout the day or week. Using HCD to promote a flexible zero-trust security model ensures seamless transitions between different healthcare symptoms without compromising data security. Zero-trust’s adaptive approach means that as healthcare professionals move, their authentication and access controls are continuously updated. This dynamic adjustment helps maintain security without disrupting workflow. For instance, while a user’s credentials might be valid across multiple locations, a flexible zero-trust approach verifies their current location and request, ensuring that access is granted only to appropriate resources and sensitive data based on their specific location and role.
Importance of Implementing HCD in a Zero-Trust Model
The zero-trust model transforms cybersecurity in healthcare by addressing the complexities of user authentication and access control. By implementing HCD to move beyond a one-size-fits-all solution, zero-trust ensures continuous protection for sensitive patient data while accommodating the diverse needs of healthcare systems. Whether users are within a single facility or transitioning between locations, zero-trust with HCD offers a flexible, dynamic approach to protecting sensitive patient data. This not only enhances data protection but also supports the efficient operation of healthcare systems, ensuring both security and seamless user experience.
