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).
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.

Example of passwordless authentication with a passkey (Pixiv with Bitwarden) Passwordless authentication is an authentication method in which a user can log in to a computer system without entering (and having to remember) a password or any other knowledge-based secret. In most common implementations users are asked to enter their public ...
In another example, if two objects X and Y are combined, they form another object Z, which is assigned the security level formed by the join of the levels of X and Y. LBAC is also known as a label-based access control (or rule-based access control ) restriction as opposed to role-based access control (RBAC).

One way to improve software security is to gain a better understanding of the most common weaknesses that can affect software security. With that in mind, there is a current community-based program called the Common Weaknesses Enumeration project, [2] which is sponsored by The Mitre Corporation to identify and describe such weaknesses. The list ...
According to the model, the protection state of a computer system can be abstracted as a set of objects , that is the set of entities that needs to be protected (e.g. processes, files, memory pages) and a set of subjects , that consists of all active entities (e.g. users, processes).
