Seadetepõhine

Seadetepõhine is a term used in information security to describe approaches that rely on the device itself as a key factor in authentication and access control. In practice, trust is anchored in device identity, integrity, and security posture rather than solely on user credentials.

Common techniques include device certificates installed in secure elements or trusted platform modules, hardware-backed keys, device fingerprinting, and continuous posture assessment. Devices can be registered with an identity provider or enterprise IAM, and access decisions may depend on the device being managed, updated, not jailbroken or rooted, and running approved operating system versions.

Applications include enterprise VPNs, cloud services, and internal networks where conditional access policies require device compliance. Device-based methods are often used in conjunction with other factors, such as passwords or biometrics, to form multi-factor authentication and to support scenario-specific requirements like remote work.

Advantages of seadetepõhine include reduced reliance on user passwords, improved resistance to credential theft and phishing, and the ability to enforce policy-based access. It can enable smoother or frictionless login within trusted environments and supports centralized monitoring of device health and compliance.

Limitations and challenges include privacy concerns related to device telemetry and monitoring, risks arising from device loss or compromise, and the complexity of managing device trust across diverse platforms. Interoperability issues, the need for robust revocation and update mechanisms, and potential vendor lock-in are also considerations.

Relation to broader concepts: device-based approaches are part of modern zero-trust security and identity and access management. They complement or, in some cases, reduce reliance on traditional password-first models and are increasingly supported by major IAM and mobile device management solutions.
