The Cyber-Physical Attack Surface of Legacy Scada Networks: A Systematic Review of Vulnerabilities, Threats, and Detection Gaps in Critical Infrastructure

Legacy Supervisory Control and Data Acquisition (SCADA) networks remain the operational backbone of the electric power, water treatment, and oil-and-gas sectors, yet they were engineered in an era that prioritized deterministic availability and physical safety over information security. The progressive convergence of i...

An Autonomous, Continuously-Learning Framework for Real-Time Cyber-Physical Threat Prevention in Legacy SCADA Systems

Supervisory Control and Data Acquisition (SCADA) systems remain the operational backbone of critical infrastructure, yet a vast installed base of legacy deployments was engineered for availability and determinism rather than security. These systems typically lack transport encryption, device authentication, and message...

AI-Based Security Posture Management as an Enabling Layer for Real-Time NIST Cybersecurity Framework Adherence: A Theory- Grounded Conceptual Framework

A theory-grounded conceptual framework is developed that positions AI-Based Security Posture Management (ASPM) as the enabling layer through which CSF functions are transformed from periodically evidenced artifacts into continuously operating control mechanisms.

Semantic De-Duplication of Shared Cyber Threat Indicators using Large Language Model Embeddings

As defence agencies, allied partners, and cybersecurity firms exchange threat intelligence, the same indicator is frequently reported many times in slightly altered form, producing large-scale duplication across intelligence repositories. Traditional de-duplication relies on exact matching using hashes or literal text...

Natural Language Processing for Real-Time Semantic Correlation of Shared Cyber Threat Indicators in National Defense

Defense intelligence systems receive continuous streams of natural-language threat reports in which the same event is frequently described using different terminology, structure, and coded language. Traditional keyword systems classify such reports as unrelated, fragmenting the intelligence picture and delaying coordin...

The Compliance Gap: Why Audit-Based Cybersecurity Models Fail Critical Infrastructure and the Case for Continuous Control

A conceptual review argues that this model is structurally incapable of guaranteeing security in modern CI environments and develops the case for a transition to continuous monitoring and continuous control and traces the intellectual and regulatory lineage of the alternative.
