IoT Security Landscape
The proliferation of IoT devices introduces significant vulnerabilities across perception, network, and application layers. Traditional security methods often fail due to device heterogeneity and resource constraints, making advanced AI solutions crucial. This section explores the architectural vulnerabilities and common attack surfaces that modern IoT systems face.
Key challenges include physical tampering, insecure data transmission, weak authentication, and application-layer attacks. Effective intrusion detection must overcome these limitations without overburdening constrained devices.
AI & LLMs for Cybersecurity
Artificial Intelligence, particularly Large Language Models (LLMs), offers powerful capabilities for securing IoT systems. LLMs excel at contextual understanding and anomaly detection, transforming how enterprises detect and respond to cyber threats. This includes advanced malware classification, phishing detection, and comprehensive log analysis.
However, deploying LLMs in resource-constrained IoT environments requires significant optimization, including model compression and hybrid edge-cloud architectures. This research highlights the need for robust, efficient, and privacy-preserving AI models to address evolving threat landscapes.
SEED Framework Details
The Semantic Embeddings for Efficient Detection (SEED) framework introduces a novel collaborative Edge-to-IoT learning scheme. It leverages a fine-tuned, lightweight BERT model at the edge to generate semantically rich network traffic embeddings. These embeddings are then offloaded to a compact neural network on IoT devices for rapid and accurate intrusion detection.
This approach significantly reduces the computational burden on IoT devices, enabling high detection accuracy (99.9%) with minimal inference latency (under 70ms on CPU) and a tiny model footprint (137KB for the IoT classifier).

Case Study: Real-time Threat Detection in Smart Homes
A smart home ecosystem struggled with real-time intrusion detection due to the diverse, resource-constrained IoT devices and the rapid evolution of cyber threats. Traditional IDSs were either too heavy for the devices or missed sophisticated anomalies.
By implementing the SEED framework, the home's gateway (edge device) ran a compact EdgeBERT model to generate contextual embeddings of network traffic. These embeddings were then fed to tiny neural networks deployed on individual smart devices for instant classification.
Outcome: The system achieved a 99.9% detection accuracy with an average 70ms inference latency per device, drastically reducing false positives and enabling proactive threat mitigation without impacting device performance.
