## Summary
HRU is a computer security model. As an instance of the "computer security model" class, HRU is a scheme for specifying and enforcing security policies and is represented in multiple public knowledge resources.

## Key Facts
- HRU is an instance of the computer security model class.
- HRU is described on Wikipedia under the title "HRU (security)".
- HRU has a Freebase identifier of /m/0d5ngx.
- Wikipedia coverage for HRU exists in at least four languages: English, French, Hebrew, and Russian.
- The entity has a sitelink count of 4 in the provided metadata.
- As a computer security model, HRU belongs to a class of schemes used to specify and enforce security policies.
- Computer security models (the class HRU belongs to) may be founded upon a formal model of access rights, a model of computation, a model of distributed computing, or no theoretical grounding.
- Computer security models (the class HRU belongs to) are implemented through a computer security policy.

## FAQs
### Q: What is HRU?
A: HRU is a computer security model — a scheme for specifying and enforcing security policies. It is documented under the Wikipedia title "HRU (security)" and appears in multiple language editions.

### Q: Where can I find more information about HRU?
A: Public documentation for HRU includes a Wikipedia page titled "HRU (security)" available in English, French, Hebrew, and Russian. HRU is also identified in knowledge-graph data with Freebase id /m/0d5ngx.

### Q: What does it mean that HRU is a "computer security model"?
A: Being a computer security model means HRU is part of a class of schemes used to specify and enforce security policies. Such models may be founded on formal models of access rights, computation, or distributed computing, or they may lack a formal theoretical grounding.

## Why It Matters
HRU matters because it is a documented example of a computer security model — a category of formal and informal frameworks used to define who can access which resources under what conditions. Computer security models provide the conceptual basis for implementing and reasoning about access control and authorization in computing systems. They are used to translate security requirements into enforceable policies and to evaluate whether a system's design meets those requirements. By being represented in major knowledge resources (Wikipedia in multiple languages and structured data like Freebase), HRU is accessible to researchers, practitioners, and learners who are studying access control frameworks and security policy specification. Understanding instances of the computer security model class helps practitioners select appropriate policy mechanisms and informs the design of secure systems across different technical contexts.

## Notable For
- Being an identified instance of the computer security model class.
- Having a dedicated Wikipedia page under the title "HRU (security)".
- Presence in multiple language Wikipedias (English, French, Hebrew, Russian).
- Having a Freebase identifier (/m/0d5ngx) and a sitelink count of 4 in the provided metadata.

## Body
### Identification
- Title: "HRU (security)" as listed in Wikipedia metadata.
- Freebase id: /m/0d5ngx.
- Sitelink count: 4.
- Wikipedia languages listed: en, fr, he, ru.

### Classification
- Instance of: computer security model.
- Class description (applies to HRU as an instance): a computer security model is a scheme for specifying and enforcing security policies.
- Implementation note (class-level): computer security models are implemented through a computer security policy.

### Conceptual context
- Computer security models may be founded upon:
  - a formal model of access rights,
  - a model of computation,
  - a model of distributed computing,
  - or no theoretical grounding at all.
- HRU, as an instance of this class, is therefore situated within that range of possible theoretical foundations.

### Representation in knowledge bases

- HRU is indexed in structured knowledge data with Freebase id /m/0d5ngx.
- The provided metadata records HRU's sitelink count as 4.

### Related concepts
- HRU is related to the broader concept "computer security model" (class). This class covers various schemes for access control and policy enforcement in computing systems.
