The number of connected devices has increased substantially in recent years, from devices that process health data: smartwatches, scales or bracelets, to devices that handle home security such as electronic locks.
The widespread use of these devices has led to an increase on the attack surface exposed to malicious actors, both for the company that manages them and for the users who use them on a daily basis.
To assess the security status of these technologies, attacks are modeled depending on the specifications of the device and the data it manages.
The result of this IoT security audit effort will allow the client to know the security stance of its infrastructure including possible solutions to the problems found.
The benefits of the execution of IoT security testing include but are not limited to:
Knowing the potential security problems within the device, including open debug ports, or vulnerabilities in the rest of the components of the embedded operating system.
Understanding the security flaws in the device data flow: in the local connections through short-range networks, in its processing on company servers if any, as well as possible solutions at both technical and design levels.
Analysis of the security implications derived from the structure and technologies used by the IoT framework.
IoT security testing is the process of evaluating IoT devices to find security vulnerabilities in both hardware and software. The testing process must consider risks to both device and network assets to ensure secure operation and avoid unwanted access from malicious actors.
In summary, security testing in IoT identifies threats and vulnerabilities to avoid unwanted network access, data manipulation, information exfiltration, privacy issues or any other kind of attack.
Security requirements specify security necessities that must be accounted for and they are usually categorized in:
Overall, it’s important to ensure security by default as part of the development and installation process, using security tested software when possible.
The best practices in security teaches the best way to perform a security assessment is to use a standard or a guide to test the more usuals weakness. The OWASP Top 10 Internet of Things (2018) standard aim to test these:
