Automated security testing to provide more protection from the start

Our daily life is becoming faster, smarter and well-connected. However, between the positive developments of digitalization and the growing possibilities to connect products via the web, equally waits a challenge: Hacker attacks are not only increasing in number, they are becoming more complex. This fact alone raises the importance of cyber security. Bosch Research is working on solutions to make software more secure from the get-go, starting with the development process. This is only possible with a highly automated code analysis performed during software development.

“Smart Times“ and the answer by Bosch

IT security is a key enabler for connected products at Bosch. These products are mainly software driven ranging from a connected sensor to an autonomous car that is connected and all the way to smart home solutions. Connectivity exposes our products to cyber-attacks and the subtlest of these attacks happen remotely without needing any physical access to the product.

In practice, most attacks exploit flaws or weaknesses of the software. Software vulnerabilities are a large, and if not the largest security concern in connected products and the Internet of Things (IoT).

As modern software has several million lines of code, the manual search for vulnerabilities is impractical. Therefore, automated security tests are important to identify these software vulnerabilities that could compromise the security of our products.

For these reasons, a core objective of our research is to explore an effective methodology, tooling and infrastructure to allow us to perform automated security tests.

The solution: automated security testing

Conserving resources, optimal use of capacities and competencies – this has never been more relevant. The same goes for the field of automated discovery of security vulnerabilities, where existing code analysis workflows are optimized. Or simply put: to automate – while developing. Approaches such as automated bug search, automated code analysis and automated security testing are at the core of further development at Bosch Research.

For this, a Bosch research project named “Software Dependability Assurance” – short: SoDA – is focusing on automated security testing. 

Bosch Research is working on a solution for the automated security testing of software, specifically tailored to Bosch connected products. This solution is based on a platform that enables continuous security analysis and testing throughout all phases of software development. The main focus of the platform is the automated discovery of software vulnerabilities within the source code. Software testing and the correlated discovery of security vulnerabilities in the source code are already fully automated and autonomous during the development phase. This is what we call “automated security testing” and it offers noticeable added value. As soon as the automated bug search is incorporated in the development process, work becomes more efficient and it is possible to react faster to the discovery of security vulnerabilities, leading to increased safety and a more efficient process.

In a nutshell, for developers automated code testing means:

Thus, according to Heise: “Things decide what action makes economic sense from their perspective and that of the person on whose behalf they are acting.” This is the economy of things at its most basic. “Our prototype demonstrates how things can negotiate and exchange real numbers back and forth. Being connected delivers economic value.”

Automated security testing allows us to perform industrial-scale bug detection early on in the development process. This, in turn, can significantly increase the software quality.

Automated security testing and the associated automated discovery of security vulnerabilities offers a comprehensible advantage to developers: The automated search for security vulnerabilities reduces manual effort significantly. As errors can be identified during the development process, automated code testing also helps increase the overall security of the systems.

The goal of our research

“IT giants like Microsoft, Google have white hat teams to test their products for security vulnerabilities internally before release. Within the SoDA project, the experts in my team have built a prototype that allows us to perform such kind of testing for Bosch’s connectivity-based products at scale.“
Rakshith Amarnath, Project Leader of the SoDA project within Bosch Research

Our research goal is to find the sweet spot in terms of automation when it comes to security testing Bosch’s connected product family. For this, we are prototyping a platform that continuously inspects software for vulnerabilities throughout all phases of software development. We strive to automate the discovery of software vulnerabilities in order to ease software development. For software development, it means that the teams can continue focusing on functionality while benefiting from our automated security testing pipeline. This forms the basis for secure, reliable and innovative Bosch products.
