How does SSO handle authentication for mobile and web-based healthcare solutions?

由人工智能和领英社区提供技术支持

Single sign-on (SSO) is a network security method that allows users to access multiple applications or services with one login credential. SSO can simplify the authentication process for mobile and web-based healthcare solutions, which often involve sensitive data and multiple platforms. In this article, you will learn how SSO works, what benefits it offers, and what challenges it faces for healthcare applications.

1 How SSO works

SSO uses a centralized authentication server that verifies the user's identity and grants access to multiple applications or services that trust the server. The user only needs to enter their username and password once, and then the server issues a token or a cookie that authenticates the user for other applications or services. The token or cookie contains information about the user's identity, roles, permissions, and session duration. The applications or services validate the token or cookie and allow the user to access their features without asking for another login.

- Device needs to be registered in one primary Identity Provider - Additional attributes about the user of the device must be registered as well - Systems must be in place to store conditional access that will act on signals coming from the device and user and act on action groups (step up authentication, allow without challenge, reject, etc.) - the federated Identity provider must have a trust relationship with the primary Identity Provider (IdP) - transferring SSO authentication data from the device to the federated IdP must be considered for security vulnerabilities

2 Benefits of SSO

Single Sign-On (SSO) can offer several benefits for mobile and web-based healthcare solutions, such as an improved user experience due to not having to remember and enter multiple passwords, enhanced security from using stronger passwords and central management of user accounts, policies, and permissions, as well as reduced costs from saving time and resources for users and administrators. SSO can also reduce the risk of phishing, hacking, or identity theft while improving compliance and auditability.

3 Challenges of SSO

Single Sign-On (SSO) can present some challenges when utilized in mobile and web-based healthcare solutions. This includes complexity, as SSO requires a reliable and secure authentication server that can communicate with multiple applications or services, often using different protocols, standards, and architectures. Additionally, SSO creates a single point of failure, meaning if the authentication server is down or compromised, users may lose access to all applications or services that rely on it. Moreover, SSO can expose sensitive information about the user's identity, activities, and preferences to the authentication server and the applications or services that use it. This may raise legal and ethical issues regarding the consent, ownership, and protection of the user's data. Therefore, careful integration and testing is necessary to ensure compatibility and functionality. Furthermore, SSO depends on the network availability and performance which can affect the user experience and security.

4 SSO methods

Different methods of implementing SSO for mobile and web-based healthcare solutions can be used, depending on the type and level of authentication required. OAuth is an open standard that allows users to authorize third-party applications or services to access their data or resources from another provider, using tokens that grant specific and limited access rights. OpenID Connect is an extension of OAuth that provides additional information about the user's identity, such as name, email, or profile picture. SAML is an XML-based standard that allows users to access applications or services across different domains or organizations, using an identity provider that authenticates the user and sends a SAML assertion containing the user's attributes and assertions to the service provider.

Few other methods can be considered for implementing SO for mobile and web-based applications as follows: JWT (JSON Web Tokens) CAS (Central Authentication Service): Shibboleth (Open Source)

5 SSO best practices

To ensure the effectiveness and security of SSO for mobile and web-based healthcare solutions, it is important to choose the appropriate SSO method that meets the requirements and standards of the applications or services, as well as the user's expectations and preferences. Additionally, strong encryption, hashing, and signing of the tokens, cookies, or assertions should be implemented. Secure protocols such as HTTPS, SSL, or TLS should also be used for communication between the authentication server and the applications or services. Monitoring and auditing SSO activities and events is essential for detecting any anomalies, errors, or breaches. Finally, users and administrators should be educated on the benefits and risks of SSO, with clear policies and guidelines in place for its use and management.
