Revolutionizing Access Control with NLP-driven Attribute Embeddings
This paper introduces a groundbreaking word-embedding approach that significantly enhances attribute-based access control (ABAC) models. By capturing contextual meaning from attribute values—even newly introduced ones—our method achieves over 93% accuracy, reducing manual intervention and improving security posture in complex, dynamic systems.
Executive Summary: Key Performance & Strategic Implications
Our novel word-embedding technique for ABAC models demonstrates superior adaptability and precision, especially in environments with evolving system attributes. This translates to substantial operational efficiency gains and a more robust, context-aware security framework.

Our FastText-based approach consistently outperforms traditional and deep learning alternatives, particularly in scenarios involving dynamic, evolving attribute sets. The results demonstrate significant improvements in accuracy and adaptability.
| Model | Accuracy (Known Tokens) | Accuracy (Unknown Tokens) | Key Advantage |
|---|---|---|---|
| FastText + XGBoost (Our Approach) | 95.27% (128k dataset) | 94.46% (Group 0) |
|
| Token2Vec + XGBoost | 93.28% (128k dataset) | 92.09% (Group 0) |
|
| DLBAC (SOTA) | 82.09% (128k dataset) | Not Applicable (rule-based or needs full retraining) |
|
A key innovation is our model's ability to maintain high predictive accuracy even when confronted with attribute values not present during its initial training. FastText's subword embedding mechanism enables robust generalization, crucial for real-world system evolution. (Accuracy from Group 4, FastText row in Table 3)

Real-world Efficacy: Amazon Access Samples Dataset
The model was rigorously tested on a large-scale, real-world dataset comprising over a billion access requests from Amazon employees. This dataset, while challenging due to its sparsity and imbalance, provided a robust testing ground for our approach.
Our technique addresses critical enterprise challenges such as reducing manual intervention in access control policy management and improving decision-making efficiency in complex, dynamic IT environments.
The ability to handle unknown tokens without retraining the embedding layer signifies a major leap in developing lightweight, scalable solutions for cloud and fog computing where resources may be limited.
