SAP’s security vision is built on 5 ideals to secure business: Defendable Application, Zero-Knowledge, Zero-Vulnerability, Security by Default, and Transparency.

SAP’s security research group lays the foundation for realising the vision: The 30 researchers of the Security Research unit focus on security engineering (e.g., the automation of the secure software development lifecycle), secure business execution (e.g., business process security and security in cloud based business applications) and secure operations (e.g., secure maintenance and support of complex and heterogeneous cloud IT landscapes).

Security Research at proposes a 6-month internship in its Sophia-Antipolis offices (Mougins, France).

Internship Topic

Modern web application scenarios are multi-party. In fact, they rely on core trusted third-party systems (e.g., payment servers, identity providers) and protocols (e.g., Cashier-as-a-Service, Single Sign-On) to deliver business services to users. Many vulnerabilities have been reported in the past over these critical scenarios and a lot of work has been done in literature to detect and mitigate these issues. In previous work, [NDSS2016], we have been focusing on black-box security testing approaches to detect hard-to-spot attacks (e.g., replay attacks) plaguing modern multi-party web applications (e.g., online shopping integrated with Paypal).

In this specific internship we aim at studying runtime prevention of logic flaws, extending the work done in [USENIX2018] to possibly cover all the logic flaws detectable in [NDSS2016].

More specifically, the goals of the internship are as follows:

  • Understanding the SAP development process

  • Studying logic flaws vulnerabilities and related state-of-the-art

  • Designing and developing an approach for runtime prevention of logic flaws

  • Deploying and assessing the approach against real world (SAP and non-SAP) environments

  • Documenting the developed software and the overall activities

Technologies/techniques involved are: Python, JavaScript, Java.

We expect that 50% of time will be dedicated to research activities, and 50% to development.

Candidate Profile
