Attribution Theory

Attribution Theory

Behavior is a product of both the situation (e.g., cultural influences, social roles, and the presence of bystanders) and of the person (e.g., personality characteristics). Subfields of psychology tend to focus on one influence or behavior over others. Situationism is the view that our behavior and actions are determined by our immediate environment and surroundings. In contrast, dispositionism holds that our behavior is determined by internal factors (Heider, 1958).

Fundamental Attribution Error

Fundamental Attribution Error

According to some social psychologists, people tend to overemphasize internal factors as explanations—or attributions—for the behavior of other people. They tend to assume that the behavior of another person is a trait of that person, and to underestimate the power of the situation on the behavior of others. They tend to fail to recognize when the behavior of another is due to situational variables, and thus to the person’s state. This erroneous assumption is...

Attribution

Attribution

In social interactions, individuals frequently seek to understand the motivations and causes behind others' behaviors. This fundamental aspect of social perception, known as attribution, plays a crucial role in shaping interpersonal relationships and guiding future actions. Attribution refers to the cognitive process through which people infer the reasons behind others' behaviors, allowing them to assess character traits, intentions, and situational influences.Attribution Theory and Its...

Distance Corrections

Distance Corrections

To achieve precise distance measurements, especially in surveying and construction, certain corrections must be applied to account for potential sources of error like the standardization errors, temperature variations, and slope adjustments.Standardization error emerges when measurement equipment undergoes changes, such as wear, repairs, or weather impacts. To address this, surveyors compare the equipment’s readings to a standard. This process identifies any deviation that might lead to...

Power Factor Correction

Power Factor Correction

The power transmission to a factory involves the transfer of apparent power, a combination of active and reactive power. The power factor measures how effectively electrical power is converted into useful work output. The ratio of the real power (KW) that does the work to the apparent power (KVA) supplied to the circuit.

Personal Choice and Fate Attributions

Personal Choice and Fate Attributions

Some individuals interpret life events as a consequence of their personal choices and actions, while others believe that outcomes are dictated by fate or destiny. This divergence in perspective has been examined in psychological and cross-cultural studies, particularly in relation to religious faith and cultural beliefs about causality.Fate and Personal ResponsibilityPeople who emphasize personal responsibility view events as direct consequences of their decisions. For instance, breaking a leg...

Resumen

Este resumen es generado por máquina.

Las políticas de Control de Acceso Basado en Atributos (ABAC) pueden tener consecuencias no deseadas debido a la semántica de los atributos de los objetos. Esta investigación distingue dos semánticas de ABAC, destacando riesgos y proponiendo soluciones para un control de acceso seguro.

Ciencias de la Computación
Seguridad de la Información
Sistemas de Control de Acceso

Sus antecedentes:

El Control de Acceso Basado en Atributos (ABAC) ofrece seguridad dinámica, flexible, portátil y escalable.
Los modelos actuales de ABAC asumen una herencia jerárquica donde el acceso a un objeto general implica el acceso a sus subtipos.
Esta suposición puede conducir a vulnerabilidades de seguridad cuando los datos específicos son más sensibles que los datos generales.

Objetivo del estudio:

Desafiar la comprensión convencional de la semántica de ABAC.
Diferenciar entre dos semánticas distintas de ABAC basadas en la interpretación de los atributos del objeto.
Identificar y abordar posibles configuraciones erróneas de seguridad derivadas de estas semánticas.

Principales métodos:

Análisis conceptual de la semántica de ABAC.
Desarrollo de ejemplos concretos que ilustran las dos semánticas identificadas.
Evidencia empírica y anecdótica de los riesgos de seguridad asociados con las implementaciones actuales de ABAC.
Propuesta de modificaciones a los algoritmos de ABAC existentes para mejorar la seguridad.

Principales resultados:

Identificadas dos semánticas distintas de ABAC basadas en la interpretación de los atributos del objeto.
Demostrado que la comprensión convencional de la herencia jerárquica puede ser inapropiada y conducir a brechas de seguridad.
Validado empírica y anecdóticamente los riesgos de malinterpretar la semántica de ABAC.
Propuestas de modificaciones a los algoritmos existentes para prevenir configuraciones erróneas y garantizar la seguridad.

Conclusiones:

La interpretación estándar de la semántica de ABAC no es universalmente aplicable.
Ignorar los matices de la semántica de los atributos de los objetos puede conducir a fallos de seguridad significativos.
Se requieren algoritmos de ABAC modificados para garantizar una seguridad robusta y prevenir configuraciones erróneas en diversos escenarios.
