Cybersecurity & Threat Detection: Leveraging graph analytics to counter cyber threats 

Graph analytics plays a crucial role in cybersecurity by uncovering relationships between entities like users, devices, and transactions. It enables detection of complex attack patterns, such as lateral movements or phishing campaigns. By visualizing and analyzing network connections, organizations can identify anomalies, predict threats, and strengthen defenses against evolving cyberattacks.

Key Applications in Cybersecurity:

  1. Anomaly Detection: Graph analytics can identify unusual patterns in network traffic, such as unauthorized access attempts, irregular data flows, or atypical user behavior. For example, if an employee's account suddenly communicates with sensitive servers it normally doesn't access, the system can flag this as suspicious.

  2. Advanced Threat Detection: Graphs excel at identifying sophisticated threats like Advanced Persistent Threats (APTs), which often involve lateral movements across a network. By mapping and analyzing the sequence of events and connections, security teams can uncover hidden attack vectors that traditional methods might miss.

  3. Fraud Detection: In industries like banking and e-commerce, graph analytics is used to detect fraud by spotting unusual connections between accounts, transactions, or devices. For instance, a shared IP address or device across multiple flagged accounts could indicate a coordinated fraud attempt.

  4. Phishing and Malware Analysis: By analyzing email communication patterns or the spread of malware across endpoints, graph models can identify potential phishing campaigns or the proliferation of malicious software within an organization.

  5. Vulnerability Assessment: Graphs can model an organization's infrastructure, highlighting weak points where attackers might exploit vulnerabilities. These insights help prioritize patching efforts and resource allocation.

Benefits of Leveraging Graph Analytics:

  • Real-Time Insights: Continuous monitoring and graph-based anomaly detection enable organizations to respond quickly to threats.
  • Visualization: Graphs offer intuitive visual representations of complex relationships, making it easier for security teams to understand attack paths and dependencies.
  • Predictive Analysis: Machine learning models integrated with graph data can predict potential threats based on historical patterns and trends.

Global Lighthouse Network

Smart, sustainable manufacturing: 3 lessons from the Global Lighthouse Network Launched in 2018, when more than 70% of factories struggled to scale digital transformation beyond isolated pilots, the Global Lighthouse Network set out to identify the world’s most advanced production sites and create a shared learning journey to up-level the global manufacturing community. In the past seven years, the network has grown from 16 to 201 industrial sites in more than 30 countries and 35 sectors, including the latest cohort of 13 new sites. This growing community of organizations is setting new standards for operational excellence, leveraging advanced technologies to drive growth, productivity, resilience and environmental sustainability. But what exactly is a Global Lighthouse and what has the network achieved? What is the Global Lighthouse Network? The Global Lighthouse Network is a community of operational facilities and value chains that harness digital technologies at scale to ac...

Multi-Modal Data

Multi-Task Federated Split Learning Across Multi-Modal Data with Privacy Preservation With the advancement of federated learning (FL), there is a growing demand for schemes that support multi-task learning on multi-modal data while ensuring robust privacy protection, especially in applications like intelligent connected vehicles. Traditional FL schemes often struggle with the complexities introduced by multi-modal data and diverse task requirements, such as increased communication overhead and computational burdens. In this paper, we propose a novel privacy-preserving scheme for multi-task federated split learning across multi-modal data (MTFSLaMM). Our approach leverages the principles of split learning to partition models between clients and servers, employing a modular design that reduces computational demands on resource-constrained clients. To ensure data privacy, we integrate differential privacy to protect intermediate data and employ homomorphic encryption to safeguard client m...

Intelligent visual question answering in TCM education: An innovative application of IoT and multimodal fusion This paper proposes an innovative Traditional Chinese Medicine Ancient Text Education Intelligent Visual Question Answering System ( TCM-VQA IoTNet ), which integrates Internet of Things (IoT) technology with multimodal learning to achieve a deep understanding and intelligent question answering of both the images and textual content of traditional Chinese medicine ancient texts. The system utilizes the VisualBERT model for multimodal feature extraction, combined with Gated Recurrent Units (GRU) to process time-series data from IoT sensors, and employs an attention mechanism to optimize feature fusion, dynamically adjusting the question answering strategy. Experimental evaluations on standard datasets such as VQA v2.0, CMRC 2018, and the Chinese Traditional Medicine Dataset demonstrate that TCM-VQA IoTNet achieves accuracy rates of 72.7%, 69.%, and 75.4% respectively, with F1-...
