Cyber Threat Ontology and Adversarial Machine Learning Attacks: Analysis and Prediction Perturbance

Machine learning has been used in the cybersecurity domain to predict cyberattack trends. However, adversaries can inject malicious data into the dataset during training and testing to cause perturbance and predict false narratives. It has become challenging to analyse and predicate cyberattack correlations due to their fuzzy nature and lack of understanding of the threat landscape. Thus, it is imperative to use cyber threat ontology (CTO) concepts to extract relevant attack instances in CSC security for knowledge representation. This paper explores the challenges of CTO and adversarial machine learning (AML) attacks for threat prediction to improve cybersecurity. The novelty contributions are threefold. First, CTO concepts are considered for semantic mapping and definition of relationships for explicit knowledge of threat indicators. Secondly, AML techniques are deployed maliciously to manipulate algorithms during training and testing to predict false classifications models. Finally, we discuss the performance analysis of the classification models and how CTO provides automated means. The result shows that analysis of AML attacks and CTO concepts could be used for validating a mediated schema for specific vulnerabilities.
