Securing the Internet of Things: A Comprehensive Guide to Implementing Cybersecurity Measures for IoT Devices Research Disclaimer: This guide is based on ESP32 Arduino Core v2.0.14+, PubSubClient (MQTT) v2.8+, ArduinoJson v6.21+, and OpenSSL/mbedTLS v2.28+ official documentation. All code examples follow OWASP IoT Top 10 security guidelines and include production-tested patterns for device authentication, encrypted communication, and firmware integrity. IoT security requires defense-in-depth—no single technique is sufficient. IoT devices are uniquely vulnerable: they’re resource-constrained, physically accessible, and often deployed in unmonitored locations. The 2016 Mirai botnet (which compromised 600,000 IoT devices) and recent attacks on medical IoT devices underscore the critical need for robust security. This guide provides complete, production-ready implementations for securing IoT devices. ...

As a SOC analyst, one of the most critical tasks is analyzing network flow data to identify potential security threats. In this post, we’ll explore how to combine cloud-based data storage, SQL querying, and AI-powered analysis to streamline this process. Collecting Flow Data in Amazon Athena Amazon Athena provides a serverless query service that makes it easy to analyze data directly in Amazon S3 using standard SQL. Here’s how we set up our flow data collection: ...
