IoT Security Auditing - OWASP Top 10

1. Introduction

The Internet of Things (IoT) represents a vast network of connected devices that collect and share data. However, the security of these devices is paramount, especially as they become integral to everyday life. The OWASP Top 10 provides a framework to identify and mitigate the most critical security risks associated with IoT devices.

2. Key Concepts

Security Auditing: A systematic evaluation of the security of IoT systems to identify vulnerabilities.
Threat Modeling: Identifying potential threats and vulnerabilities to the IoT ecosystem.
