TL;DR

This paper introduces an interpretable deep learning defence framework in the context of user anomaly detection for both IaaS and PaaS cloud service layers and SaaS application layer and shows that the detection accuracy and F1-score are much higher than those of the conventional rule-based and black-box deep learning IDSs.

Abstract

Cloud platforms are the targets of highly advanced attacks that are designed to circumvent traditional rule based IDSs, such as: credential misuse, insider threats, privilege escalation, lateral movements, etc. To protect against user attacks, this paper introduces an interpretable deep learning defence framework in the context of user anomaly detection for both IaaS and PaaS cloud service layers and SaaS application layer. Multi-source authentication logs/records, APIs, networks logs are combined into integrated behavioural tensors and classified as anomalies by processing with the recurrent neural network with attention-based temporal weights. The mathematical model for access probability distribution, the model for anomaly scoring and temporal sequence modeling, as well as the model for Mahalanobis-distance-based deviation analysis further enhance the analysis's rigor and interpretability. Experimental results show that the detection accuracy achieved is 97.4%, followed by 96.8% precision, 97.9% recall and 97.3% F1-score, which are much higher than those of the conventional rule-based and black-box deep learning IDSs.

Generative Adversarial Networks for Hardening Cloud Intrusion Detection Systems

Cloud computing has emerged as an important core to the contemporary digital services, facilitating scalable, on demand provisioning of resources across a variety of application fields. Nevertheless, this multi-tenant and dynamic environment of clouds and the amplified attack surface make the detection of intrusions through reliable methods a consistent issue that cloud security systems struggle with. The proposed work is a Generative Adversarial Network (GAN)-based hardening framework of cloud intrusion detection systems, targeting better resilience to changing and low-rate cyberattacks. The methodology combines a conditional generator which is used to generate realistic cloud-specific attack traffic, a discriminator used to refine the adversarial traffic, as well as a co-trained intrusion classifier trained on both clean and synthetic data in a closed-loop way. The feature-aware regularization is introduced to maintain the statistical consistency of network traffic, and optimize the attack diversity. The proposed approach is proved to yield better results in comparison with signature-based, machine learning, deep learning, and adversarial ML-based IDS models by experimental assessment. Significant gains in the accuracy of identifying, the ability to recall, stability, and minimizing errors are also noticed with quantifiable increases observed in all evaluation measures. These findings represent the usefulness of adversarial data-driven learning to develop robust, adaptive, and future-ready cloud intrusion detection systems.

AWS Security Architecture and Machine Learning for APT Detection in Cloud Environments

Cloud environments, and Amazon Web Services (AWS) in particular, host high-value data assets and mission-critical workloads that make them attractive targets for Advanced Persistent Threat (APT) actors. Because forensic investigation techniques are applied only after a breach has already been discovered, the volume and velocity of cloud-generated telemetry make proactive, automated detection capabilities essential. This paper reviews machine learning-driven anomaly detection paradigms — supervised, unsupervised, semi-supervised, and deep learning — and examines their suitability for APT detection in AWS environments. It also reviews the AWS shared-responsibility security architecture, including Identity and Access Management (IAM), encryption services, and logging and monitoring services such as AWS Cloud Trail, AWS Config, Amazon Guard Duty, Amazon Detective, and Amazon Inspector, and considers the NIST Cyber security Framework (CSF) as a governance overlay that connects these technical capabilities to organizational risk management. Drawing on this review of the peer-reviewed and primary-source literature, the paper argues that no single detection paradigm is likely sufficient on its own, and that unsupervised and semi-supervised machine learning, combined with AWS-native security services and governed by the NIST CSF, offer a more resilient conceptual basis for cloud APT defense than any single method in isolation. On this basis, the paper proposes an Integrated Cloud APT Detection and Defense Model (ICADDM) as a conceptual architecture for researchers and practitioners, maps AWS security services against the MITRE ATT&CK Cloud Matrix, and identifies the empirical validation of the model against real cloud telemetry as the principal direction for future work.
