TRAIN is presented, a TOCTOU resilient attestation technique that synchronizes network-wide attestation, enables constant-time per-device reports, and remains resilient even when multiple devices are compromised.
Abstract
Internet-of-Things (IoT) devices have become increasingly pervasive across modern society, often performing safety-critical functions. Network attestation – verifying the software state of all devices in a network – is a promising mitigation approach. However, current network attestation schemes suffer from lengthy Time-Of-Check-Time-Of-Use (TOCTOU) vulnerability windows, high latency, and interference from compromised devices. In this paper, we present TRAIN, a TOCTOU resilient attestation technique that synchronizes network-wide attestation, enables constant-time per-device reports, and remains resilient even when multiple devices are compromised.
5G networks introduce transformative technologies like SDN, NFV, Network Slicing, and MEC that enable ultra-low latency and massive IoT connectivity, but simultaneously create new security vulnerabilities. The software-defined control plane, shared infrastructure, and proliferation of insecure IoT devices make DDoS att...

The findings of this review show that proactive, cooperative, and self-healing security mechanisms are more effective than traditional reactive approaches in IoT environments and provide recommendations for developing scalable, energy-efficient, and privacy-preserving IoT security frameworks for future research.
A novel methodology which leverages Maximum Satisfiability Modulo Theories (MaxSMT) to automatically compute a formally correct and optimized allocation scheme and configuration of SDN switches by refining security policies, user-defined or derived from detected attacks is proposed.
