Abstract
Cloud Security Posture Management is a set of practices and tools designed to ensure the consistent and effective security configuration of cloud resources that involves monitoring, assessing, and managing the security posture of an organization’s cloud infrastructure to prevent and address security misconfigurations, vulnerabilities, and compliance issues. This project navigates the area of cloud security with a dual focus on fortifying the security posture and detecting anomalies within cloud traffic. A conceptual security framework is devised by integrating features from prominent cloud security frameworks. This framework serves as a comprehensive guide for managing security postures in the cloud.
Simultaneously, the study delves into anomaly detection in cloud traffic, employing the Gradient Boosting Classifier algorithm to discern deviations from established norms. Rigorous preprocessing, feature selection, and model training characterize the methodology. Applying the proposed conceptual framework and the gradient boosting classifier aligns with the dynamic nature of cloud computing environments, ensuring robust security measures and efficient identification of anomalous activities. The model achieved an accuracy of 94.57% and 96% of the F1-score, which is better when compared to the SVM (89%) and LSTM (94%) models. These evaluation factors showcase the efficacy of the approach in enhancing cloud security resilience, offering a substantial contribution to the evolving landscape of cloud security management.
