Threat assessment is a vital step in IoT security testing that identifies and evaluates possible attack vectors targeting IoT devices and systems. By analyzing the likelihood and potential impact of each threat, this phase helps prioritize high-risk vulnerabilities and guides the development of effective security measures.

Automated code review uses a range of free and commercial tools to scan large-scale codebases efficiently. These tools accelerate the review process by identifying insecure code patterns across millions of lines, allowing developers and security teams to focus on analyzing and addressing the flagged issues.

Manual code review is essential for validating critical areas like access control, encryption, data flow, logging, and backend integration. Unlike automated tools, manual inspection allows a deeper understanding of how data moves from source to sink within an application. While time-consuming, reviewing code line by line enhances readability, strengthens security posture, and helps eliminate false positives.
