A security model that assumes no user or device is trustworthy by default, regardless of their location.
Description
Zero Trust Security is a cybersecurity framework that operates on the principle of 'never trust, always verify.' In the context of Single Sign-On (SSO) protocols, this model emphasizes strict identity verification for every user attempting to access resources within an organization. Unlike traditional security models that often rely on perimeter defenses, Zero Trust does not automatically trust users inside the network. This approach requires continuous authentication and authorization, ensuring that every access request is rigorously evaluated based on the user's identity, device security status, and the specific resources being accessed. For instance, if an employee accesses their company email from a personal device, Zero Trust Security mandates that their identity be authenticated anew, even if they are already logged in to the corporate network. This model is increasingly adopted by organizations to mitigate risks associated with data breaches and insider threats, making it a critical component of modern cybersecurity strategies.
Examples
- Companies like Google utilize Zero Trust Security to protect their internal applications and data, ensuring that all access requests are verified.
- Microsoft’s Azure Active Directory employs Zero Trust principles by requiring multifactor authentication for users accessing cloud services.
Additional Information
- Zero Trust Security integrates well with SSO protocols by enhancing security without compromising user convenience.
- This approach can significantly reduce the risk of data breaches, especially in cloud environments where traditional security measures may fail.
