The PSA Certified program seeks to address and reduce fragmentation in the IoT product manufacturing and development sectors. It supports the creation of system-on-chips (SoCs) that incorporate a PSA Root of Trust (PSA-RoT), a security component accessible to software platforms and original equipment manufacturers (OEMs).

Multiple Independent Levels of Security/Safety (MILS) is a high-assurance security architecture based on the concepts of separation [1] and controlled information flow. It is implemented by separation mechanisms that support both untrusted and trustworthy components; ensuring that the total security solution is non-bypassable, evaluatable, always invoked, and tamperproof.
PSA Certified includes freely available threat models and security analyses that demonstrate the process for deciding on security features in common IoT products. [180] It also provides freely downloadable application programming interface (API) packages, architectural specifications, open-source firmware implementations, and related test suites.
This category contains articles describing computer security models that are or have been used in practical systems or proposed in theory. Subcategories This category has only the following subcategory.
A computer security model is a scheme for specifying and enforcing security policies. A security model may be founded upon a formal model of access rights, a model of computation, a model of distributed computing, or no particular theoretical grounding at all. A computer security model is implemented through a computer security policy.
The PSIA Common Security Model (CSEC) specification is the comprehensive PSIA specification for all protocol, data and user security. It covers security requirements and definitions for network and session security, key and certificate management, and user permission management. These security definitions apply to all PSIA nodes.
Capability-based security is a concept in the design of secure computing systems, one of the existing security models. A capability (known in some systems as a key) is a communicable, unforgeable token of authority. It refers to a value that references an object along with an associated set of access rights.
