  • Explainable Cyber AI

    As the use of AI applications for detecting adversarial attacks becomes more widespread, there is a growing demand for Explainable Artificial Intelligence (XAI). XAI plays a crucial role by offering transparency into the inner workings of AI systems, which are often perceived as “black boxes.” This transparency empowers Security Operations Centers (SOCs) to gain valuable insights and understanding of how AI algorithms make decisions in the context of cybersecurity.   By incorporating XAI into cybersecurity strategies, SOCs can enhance their ability to comprehend and interpret the outputs of AI models. This increased understanding allows cybersecurity professionals to identify potential weaknesses, assess the reliability of predictions, and fine-tune security measures more effectively. Essentially, XAI serves as a tool that not only detects adversarial attacks but also provides human interpretable explanations for the decisions made by AI systems, facilitating continuous improvement in cybersecurity strategies.
  • Cyber AI for IoT/OT Security

    In the realm of Internet of Things (IoT) and Operational Technology (OT) environments, the application of AI for behavior analysis is witnessing a significant expansion. Specifically, Artificial Intelligence (AI) and Machine Learning (ML) techniques are being employed to comprehend and learn the behaviors exhibited by OT devices. This utilization serves to improve the efficiency of detecting and identifying potentially suspicious activities and threats within these environments. By leveraging AI and ML algorithms, the system gains the capability to analyze and understand the regular patterns and behaviors of various OT devices. This learning process enables the system to distinguish between normal operations and deviations that may indicate potential security threats. As a result, the rapid detection of anomalies becomes more effective, allowing for swift responses to mitigate risks and safeguard the integrity of IoT and OT systems.
  • Neuromorphic Computing

    Neuromorphic computing, a cutting-edge approach inspired by the neural architecture of the human brain, is significantly elevating the impact of artificial intelligence (AI) in the field of cybersecurity. This is particularly evident in collaborative efforts between companies and academic institutions, where joint endeavors are spearheading advancements in the realm of malware detection.
