ABSTRACT
Cyber threats are evolving rapidly, posing significant risks to individuals, organizations, and digital infrastructure. Traditional cybersecurity measures, which rely on predefined rules and static defence mechanisms, struggle to counter emerging threats such as zero-day attacks and advanced persistent threats (APTs). The integration of artificial intelligence (AI) and machine learning (ML) into cybersecurity presents a transformative approach, enhancing threat detection, anomaly identification, and automated response mechanisms. This study systematically reviews the role of ML and AI in cybersecurity defence using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework. A comprehensive literature search was conducted across multiple academic databases, identifying and analyzing studies published within the last decade. The review focuses on AI-driven cybersecurity applications, including intrusion detection systems (IDS), malware analysis, and anomaly detection in cloud and IoT environments. Findings indicate that ML models, such as neural networks, support vector machines, and ensemble learning techniques, improve detection accuracy and adaptability to evolving threats. AI-driven automated response systems enhance incident mitigation, reducing reliance on human intervention. However, challenges such as adversarial attacks, data privacy concerns, and computational resource demands persist. The study concludes that AI and ML significantly enhance cybersecurity resilience but require continuous advancements in model robustness, interpretability, and ethical considerations. Future research should focus on refining AI-driven security mechanisms, addressing adversarial vulnerabilities, and improving regulatory frameworks to maximize AI’s potential in cybersecurity.

INTRODUCTION
In today’s digital landscape, cybersecurity has become an essential requirement rather than an option, as cyber threats continue to evolve at an alarming rate. Malicious actors constantly develop sophisticated techniques to exploit vulnerabilities, posing significant risks to individuals, organizations, and society.(1,2,3) Modern technological advancements, including banking systems, IoT devices, and smart cities, rely heavily on cybersecurity to ensure the integrity and confidentiality of sensitive data.(1,2,3,4,5,6) However, traditional security measures, while effective against known threats, struggle to detect emerging attacks such as zero-day exploits and advanced persistent threats (APTs), which capitalize on system vulnerabilities before they are patched.(1,2,3,4,5,6,7,8,9)
A significant limitation of conventional cybersecurity approaches, such as signature-based detection, is their reliance on predefined patterns, making them ineffective against new and evolving threats.(2) Additionally, fragmented security tools and anomaly-based detection systems often produce high false positives, creating inefficiencies in cyber defence mechanisms. This challenge highlights the need for advanced, adaptive, and intelligent cybersecurity solutions.(1,2,3,4,5)
Recent advancements in artificial intelligence (AI) and machine learning (ML) offer promising solutions to enhance cybersecurity defences. AI-driven systems can analyze vast amounts of data, detect patterns, and identify potential threats in real-time, improving accuracy and reducing false positives.(5) Moreover, ML algorithms continuously evolve by learning from new threats, making them more resilient to emerging cyber risks. These capabilities position AI and ML as transformative technologies for strengthening cybersecurity frameworks.(1,2,3,4,5,6)
Despite the growing adoption of AI in cybersecurity, there remain critical challenges such as model interpretability, adversarial attacks, and the need for high-quality training data.(1,2,3,4,5,6,7,8) Therefore, this study aims to systematically review the role of AI and ML in cybersecurity, with a focus on intrusion detection, malware analysis, and anomaly detection in IoT and cloud environments. The review will also explore the limitations and challenges associated with AI-driven cybersecurity solutions, providing insights into their effectiveness in mitigating modern cyber threats.
METHOD
This systematic literature review (SLR) rigorously examines the existing body of research on the applications of machine learning (ML) and artificial intelligence (AI) in security defence mechanisms, adhering to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) framework. PRISMA provides a structured and transparent approach for conducting systematic reviews, ensuring reproducibility and credibility in research synthesis. The study employs a multi-stage filtering process to extract, analyze, and synthesize data from scholarly sources published over the last decade (2014-2024), offering insights into trends, methodologies, and advancements in ML- and AI-driven cybersecurity defence mechanisms.
Systematic Selection Process
The selection process was carried out systematically in four key stages to ensure methodological rigour and comprehensive coverage of relevant literature:
1. Identification: A structured and exhaustive search was performed across multiple digital databases to identify relevant studies. The search strategy incorporated a combination of controlled vocabulary (e.g., MeSH terms) and free-text keywords tailored to cybersecurity, AI, and ML applications in defence mechanisms.
2. Screening: Titles and abstracts of retrieved articles were reviewed for relevance. To eliminate irrelevant studies, articles that did not align with the scope of ML- and AI-based security mechanisms were removed at this stage.
3. Eligibility: The full texts of shortlisted studies were thoroughly examined against predefined eligibility criteria to ensure methodological soundness and relevance. Studies with insufficient empirical or experimental contributions were excluded.
4. Inclusion and Exclusion: A final selection was made, including studies that met all relevance and quality criteria. Redundant and duplicate studies were removed using reference management software.
Database and Search Strategy
A comprehensive search was conducted across multiple academic databases, including ACM Digital Library, IEEE Xplore, ScienceDirect, ResearchGate, and Google Scholar. The search strategy integrated Boolean operators and structured search terms to refine the results. The keywords employed included:
• “Machine Learning in Cybersecurity”
• “AI Security Defense Mechanisms”
• “AI-based Intrusion Detection”
• “ML in Threat Detection”
• “Adversarial Machine Learning in Cybersecurity”
Search filters were applied to limit results to peer-reviewed journal articles and conference proceedings published between 2014 and 2024, ensuring the inclusion of state-of-the-art research. Additional manual searches were performed to cross-validate findings and include any seminal works that might have been overlooked by automated queries.(9,10,11,12)

The extracted data were subjected to statistical and qualitative analysis to identify recurring themes, gaps, and advancements in ML- and AI-based security mechanisms.
DEVELOPMENT
Machine Learning Applications in Security Defence
Anomaly Detection
Anomaly detection is one of the primary applications of machine learning (ML) in cybersecurity. ML models can learn typical patterns of network traffic or user behaviour and detect deviations that may signal potential threats. Common algorithms used in anomaly detection include support vector machines (SVM), neural networks, and clustering techniques like K-means.(8,9) These models are advantageous as they can automatically adapt to new threats over time, thus providing a dynamic defence mechanism.
Studies indicate that supervised learning approaches such as decision trees and random forests effectively detect anomalies in network traffic where labelled data is available. In contrast, unsupervised methods like autoencoders and K-means clustering enable the detection of previously unknown threats in situations with limited labelled data.(10,11,12,13,14) Sharma and Gupta(4) demonstrate that supervised learning models provide high accuracy but struggle with detecting new and emerging threats due to their reliance on predefined patterns. Meanwhile, Wang et al.(6) propose the use of autoencoders and K-means clustering, which facilitate unsupervised anomaly detection and can identify novel threats without requiring extensive labelled data.
Intrusion Detection Systems (IDS)
Intrusion Detection Systems (IDS) identify and respond to unauthorized access or activity within a network. Machine learning models, such as k-nearest neighbours (k-NN) and deep learning models (e.g., convolutional neural networks), have been widely adopted in IDS due to their ability to process and analyze complex data patterns.(15,16,17,18)
In IDS, supervised ML models are often trained using labelled normal and malicious network activity datasets. Studies have shown that hybrid models, combining multiple ML techniques (e.g., combining decision trees with support vector machines), can improve intrusion detection accuracy by leveraging the strengths of individual models. White et al.(7) advocate for deep learning models like CNNs for IDS due to their ability to analyze complex attack patterns. However, Zhang(13) warns about the vulnerability of these models to adversarial attacks, where slight perturbations in input data can lead to incorrect classifications. A comparative analysis by Evans(11) suggests that reinforcement learning (RL) techniques offer a promising approach to IDS by enabling adaptive responses to detected threats (table 2).

Artificial Intelligence for Threat Intelligence and Response
Threat Intelligence with Natural Language Processing (NLP)
Threat intelligence gathers data on potential or ongoing threats to analyze patterns, origins, and methods. Artificial intelligence (AI), specifically natural language processing (NLP), plays a significant role in threat intelligence by automating the analysis of large volumes of unstructured data, such as threat reports, social media posts, and news articles. NLP models extract relevant information, such as threat actors and targeted systems, allowing for more efficient threat intelligence processing.(15,16,17,18,19,20,21)
Recent advances in NLP, including Transformer models like BERT, have improved the accuracy of analyzing complex language patterns to identify emerging threats. However, these models require large amounts of training data, which may present limitations in regions with restricted data access.
AI-Driven Automated Response
AI-driven automated response systems leverage reinforcement learning (RL) to make real-time decisions on threat mitigation. When a threat is detected, RL models can automatically apply countermeasures, such as isolating affected systems, blocking malicious IPs, or alerting administrators.(22,23,24,25) Studies indicate that such systems are particularly effective in environments with high-frequency, repetitive threats (e.g., Distributed Denial of Service (DDoS) attacks). However, a significant challenge is the need for extensive training data to develop accurate RL models, making deployment more difficult in resource-limited settings (table 3).

CONCLUSION
This systematic literature review highlights the transformative potential of machine learning (ML) and artificial intelligence (AI) in enhancing cybersecurity mechanisms. By leveraging advanced ML techniques such as neural networks, support vector machines, and reinforcement learning, AI-driven systems significantly improve threat detection, anomaly identification, and automated response capabilities. These technologies excel in addressing evolving cyber threats, including zero-day attacks and advanced persistent threats (APTs), which traditional methods struggle to counter. However, challenges such as adversarial attacks, data privacy concerns, and the need for high-quality training data persist. The study underscores the importance of continuous advancements in model robustness, interpretability, and ethical considerations to maximize AI’s potential in cybersecurity. Future research should focus on refining AI-driven security mechanisms, addressing adversarial vulnerabilities, and improving regulatory frameworks. For regions like Zambia, where cybersecurity resources are limited, adopting AI and ML presents a promising opportunity to strengthen digital defences, provided there is adequate international collaboration and capacity-building support. Overall, AI and ML are pivotal in building resilient cybersecurity frameworks, but their successful implementation requires ongoing innovation and strategic planning.
