Cyber security is a critical problem that causes data breaches, identity theft, and harm to millions of people and businesses. As technology evolves, new security threats emerge as a result of a dearth of cyber security specialists equipped with up-to-date information. It is hard for security firms to prevent cyber-attacks without the cooperation of senior professionals. However, by depending on artificial intelligence to combat cyber-attacks, the strain on specialists can be lessened. as the use of Artificial Intelligence (AI) can improve Machine Learning (ML) approaches that can mine data to detect the sources of cyberattacks or perhaps prevent them as an AI method, it enables and facilitates malware detection by utilizing data from prior cyber-attacks in a variety of methods, including behavior analysis, risk assessment, bot blocking, endpoint protection, and security task automation. However, deploying AI may present new threats, therefore cyber security experts must establish a balance between risk and benefit. While AI models can aid cybersecurity experts in making decisions and forming conclusions, they will never be able to make all cybersecurity decisions and judgments.

Anomaly detection is a challenge well-suited to machine learning and in the context of information security, the benefits of unsupervised solutions show significant promise. Recent attention to Graph Neural Networks (GNNs) has provided an innovative approach to learn from attributed graphs. Using a GNN encoder-decoder architecture, anomalous edges between nodes can be detected during the reconstruction phase. The aim of this research is to determine whether an unsupervised GNN model can detect anomalous network connections in a static, attributed network. Network logs were collected from four corporate networks and one artificial network using endpoint monitoring tools. A GNN-based anomaly detection system was designed and employed to score and rank anomalous connections between hosts. The model was validated against four realistic experimental scenarios against the four large corporate networks and the smaller artificial network environment. Although quantitative metrics were affected by factors including the scale of the network, qualitative assessments indicated that anomalies from all scenarios were detected. The false positives across each scenario indicate that this model in its current form is useful as an initial triage, though would require further improvement to become a performant detector. This research serves as a promising step for advancing this methodology in detecting anomalous network connections. Future work to improve results includes narrowing the scope of detection to specific threat types and a further focus on feature engineering and selection.

Cyberattacks, particularly those that take place in real time, will be able to target an increasing number of networked systems as more and more items connect to the Internet of items. While the system is operational, it is susceptible to intrusions that might have catastrophic consequences, such as the theft of sensitive information, the violation of personal privacy, or perhaps physical injury or even death. These outcomes are all possible while the system is operational. A mixed-methods research approach was required in order to fulfill the requirements for understanding the nature and scope of real-time assaults on IoT-powered cybersecurity infrastructure. The quantitative data that was utilized in this research came from an online survey of IoT security professionals as well as an analysis of publicly available information on IoT security incidents. For the purpose of gathering qualitative data, in-depth interviews with industry experts and specialists in the area of Internet of Things security were conducted. The authors provide a novel method for identifying cybersecurity flaws and breaches in cyber-physical systems, one that makes use of deep learning in conjunction with blockchain technology. This method has the potential to be quite useful. Their proposed technique compares and evaluates unsupervised and deep learning-based discriminative methods, in addition to introducing a generative adversarial network, in order to determine whether cyber threats are present in IICs networks that are powered by IoT. The results indicate an improvement in performance in terms of accuracy, reliability, and efficiency in recognizing all types of attacks. The dropout value was found to be 0.2, and the epoch value was set at 25.

The escalating visibility of secure direct object reference (IDOR) vulnerabilities in API security, as indicated in the compilation of OWASP Top 10 API Security Risks, highlights a noteworthy peril to sensitive data. This study explores IDOR vulnerabilities found within Android APIs, intending to clarify their inception while evaluating their implications for application security. This study combined the qualitative and quantitative approaches. Insights were obtained from an actual penetration test on an Android app into the primary reasons for IDOR vulnerabilities, underscoring insufficient input validation and weak authorization methods. We stress the frequent occurrence of IDOR vulnerabilities in the OWASP Top 10 API vulnerability list, highlighting the necessity to prioritize them in security evaluations. There are mitigation recommendations available for developers, which recognize its limitations involving a possibly small and homogeneous selection of tested Android applications, the testing environment that could cause some inaccuracies, and the impact of time constraints. Additionally, the study noted insufficient threat modeling and root cause analysis, affecting its generalizability and real-world relevance. However, comprehending and controlling IDOR dangers can enhance Android API security, protect user data, and bolster application resilience.

Over the past decade, the number of cyber attack incidents targeting critical infrastructures such as the electrical power system has increased. To assess the risk of cyber attacks on the cyber-physical system, a holistic approach is needed that considers both system layers. However, the existing risk assessment methods are either qualitative in nature or employ probabilistic models to study the impact on only one system layer. Hence, in this work, we propose a quantitative risk assessment method for cyber-physical systems based on probabilistic and deterministic techniques. The former uses attack graphs to evaluate the attack likelihood, while the latter analyzes the potential cyber-physical impact. This is achieved through a dynamic cyber-physical power system model, i.e., digital twin, able to simulate power system cascading failures caused by cyber attacks. Additionally, we propose a domain-specific language to describe the assets of digital substations and thereby model the attack graphs. Using the proposed method, combined risk metrics are calculated that consider the likelihood and impact of cyber threat scenarios. The risk assessment is conducted using the IEEE 39-bus system, consisting of 27 user-defined digital substations. These substations serve as the backbone of the examined cyber system layer and as entry-points for the attackers. Results indicate that cyber attacks on specific substations can cause major cascading failures or even a blackout. Thereby, the proposed method identifies the most critical substations and assets that must be cyber secured.

The study focuses more on analyzing the key elements of IoT technologies that an organization may utilize to protect itself from security threats and take the necessary countermeasures to achieve sustainable growth. Each kind of network intrusion is thought to be linked around one or more different architectural levels; as a result, suitable authenticity, confidentially, and validation need to be established for greater protection. SPSS is utilized in the study s qualitative research design to analyses the data and offer insight based on the findings.

Cybersecurity risk analysis is crucial for orga-nizations to assess, identify, and prioritize possible threats to their systems and assets. Organizations aim to estimate the loss cost in case cybersecurity risks occur to decide the control actions they should invest in. Quantitative risk analysis aids organizations in making well-informed decisions about risk mitigation strategies and resource allocation. Therefore, organizations must use quantitative risk analysis methods to identify and prioritize risks rather than relying on qualitative methods. This paper proposes a spreadsheet-based quantitative risk analysis method based on verbal likelihoods. Our approach relies on tables constructed by experts that map between linguistic likelihood and possible probability ranges. Using linguistic terms to estimate the probability of risk occurrence will help experts apply quantitative estimation easily by using common language as input, thus eliminating the need to assign precise probabilities. We experimented with real examples to validate our approach s accuracy and reliability and compared our results with those obtained from another method. Also, we conducted tests to measure our model s performance and robustness. Our study showcases the effectiveness of our approach and demonstrates its potential for risk analysts to use it in real-world applications.
