The fusion of IoT and OT is instrumental in the propagation of edge computing in industrial settings. IoT devices equipped with edge computing capabilities analyze and process data on-site, negating the need for data transmission to centralized processing hubs. This not only reduces latency but ensures that real-time data is utilized promptly for immediate operational adjustments ## What Are the Differences Between OT and IoT Security? ![Comparative list of IoT Security and OT Security features in two colored blocks.](https://www.paloaltonetworks.com/content/dam/pan/en_US/images/cyberpedia/iot-security-vs-ot-security.png "Comparative list of IoT Security and OT Security features in two colored blocks.") Operational Technology (OT) and Internet of Things (IoT) security, though intertwined, possess distinct characteristics and challenges. OT security safeguards industrial and critical infrastructure. It focuses on the specialized hardware and software designed to monitor and control physical devices and processes. The pivotal concern is maintaining systems availability and safety. OT security is especially imperative in OT environments where system interruption or failure could lead to catastrophic outcomes. IoT security, on the other hand, concentrates on the vast array of connected devices that collect, transmit, and analyze data. These devices, often consumer-oriented, are networked and internet-enabled, amplifying the attack surface for potential cyber threats. Security for IoT involves safeguarding the integrity and confidentiality of data. While OT is primarily concerned with system availability, IoT security grapples with the myriad of devices, each with unique vulnerabilities, enhancing the complexity of securing them against cyber threats. In terms of remediation and defense strategies, OT and IoT also exhibit variations. OT systems, often being older and embedded in critical infrastructures, may be challenging to update or patch, making anomaly detection and OT network segmentation crucial. IoT devices, conversely, benefit from more flexibility in updates but are often less secure by design. Consequently, changing default credentials and regular software updates are common practices in IoT security. Although distinct, the convergence of OT and IoT is inevitable, underscoring the need for comprehensive security approaches that encapsulate the intricacies of both domains. ## IoT vs. OT Security FAQs ### What is IoT and OT security?
