Securing Internet of Things devices and the networks they connect to across enterprise environments.
IoT Security Challenges
IoT devices often have security limitations but access important networks. Security requires device inventory, vulnerability management, network segmentation, and behavioral monitoring. Organizations must balance IoT functionality with security requirements.
Device Inventory
Organizations often don't know what IoT devices are on their networks. Comprehensive device discovery is the first step. Asset management tools help maintain device inventory.
Vulnerability Management
IoT devices have vulnerabilities. Scanning tools identify vulnerable devices. Organizations should prioritize patching devices controlling critical functions.
Network Segmentation
IoT devices should be segregated from general corporate networks. Network policies should restrict what IoT devices can communicate with. This limits blast radius if devices are compromised.
Default Credentials
Many IoT devices ship with default credentials. These must be changed immediately. Organizations should enforce strong, unique credentials across all devices.
Behavioral Monitoring
Baseline normal IoT device behavior. Deviations may indicate compromise. Monitoring can detect when devices start communicating with unexpected targets or transmitting unusual volumes of data.
