Role-Based Identity01:21

Role-Based Identity

145
Role-based identities are central to understanding how individuals navigate social environments by adopting distinct self-conceptions aligned with various societal roles. These identities are not fixed traits but are constructed through personal actions and the social feedback individuals receive in context-specific interactions. Each social role, such as student, teacher, or friend, carries a set of expectations and norms that influence how people think, feel, and behave within that...

Classification of Systems-II

432
Continuous-time systems have continuous input and output signals, with time measured continuously. These systems are generally defined by differential or algebraic equations. For instance, in an RC circuit, the relationship between input and output voltage is expressed through a differential equation derived from Ohm's law and the capacitor relation,

Role of Septins01:02

Role of Septins

2.0K
Septins are the recently discovered fourth major protein component of the cytoskeleton, along with microfilaments, microtubules, and intermediate filaments. These proteins can associate with other cytoskeletal filaments and carry out varied roles or can be free-floating in the cytoplasm.
Cellular Functions of Septins
Recent studies have revealed the multifaceted roles of septins in various cellular processes such as cytokinesis, ciliogenesis, and neurogenesis. Septins act as scaffolds and...

Drug Control Governance: Regulatory Bodies and Their Impact

430
Drug control governance involves the oversight and regulation of pharmaceuticals to ensure their safety and efficacy while preventing illegal drug use and trafficking. Regulatory bodies, including the US Food and Drug Administration (FDA) and the European Union's European Medicines Agency (EMA), play a central role in this process. These agencies evaluate the safety and efficacy of drugs before they can be marketed. They fund clinical trials and assess the benefits and risks associated with...

Classification of Systems-I

505
Linearity is a system property characterized by a direct input-output relationship, combining homogeneity and additivity.
Homogeneity dictates that if an input x(t) is multiplied by a constant c, the output y(t) is multiplied by the same constant. Mathematically, this is expressed as:

Area of Science:

  • Information Security
  • Computer Science
  • Access Control Systems

Background:

  • Attribute-Based Access Control (ABAC) provides flexible, portable, and identity-less access control.
  • Existing commercial implementations for ABAC are limited, leading organizations to rely on Role-Based Access Control (RBAC) and its temporal extensions (TRBAC).
  • A gap exists in deploying advanced ABAC policies within established RBAC/TRBAC infrastructures.

Purpose of the Study:

  • To propose a method for translating Attribute-Based Access Control (ABAC) policies into a format compatible with Role-Based Access Control (RBAC) and Temporal Role-Based Access Control (TRBAC) systems.
  • To enable organizations using RBAC/TRBAC to leverage the benefits of ABAC policies, including time constraints.
  • To analyze and mitigate the security management costs associated with RBAC/TRBAC compared to ABAC.

Main Methods:

  • Developed a novel translation method to convert ABAC policies, incorporating temporal constraints, into RBAC/TRBAC-executable formats.
  • Conducted experimental evaluations to compare the access request evaluation times between ABAC, RBAC, and TRBAC systems.
  • Performed a comparative analysis of security management costs, considering various administrative operations for RBAC/TRBAC versus ABAC.

Main Results:

  • Access request evaluation in RBAC and TRBAC systems was experimentally demonstrated to be significantly faster than in corresponding ABAC systems.
  • The study identified that RBAC systems incur higher security management costs compared to ABAC.
  • Mitigation strategies for management costs were proposed through the analysis of administrative operations.

Conclusions:

  • The proposed translation method effectively bridges the gap between ABAC policy capabilities and RBAC/TRBAC system implementations.
  • This approach enhances access control efficiency by leveraging RBAC/TRBAC's performance while enabling ABAC policy deployment.
  • Addressing management cost differences is crucial for the practical adoption of these hybrid access control strategies.
