IT Security Assessment of an International Stockbroker Platform with Real-Time Data, Mobile App and TAN App
As part of a project, we carried out a comprehensive assessment of an international online broker’s systems. The trading platform is built on a distributed microservice architecture providing real-time data via WebSockets. In addition to the platform itself, the mobile application and a dedicated TAN app for transaction authorization were analyzed.
The assessment focused on authentication mechanisms, session management, encryption of data flows, and the security of exposed API endpoints. Particular attention was given to transaction integrity and the protection of sensitive customer data against unauthorized access or manipulation. The findings provided a basis for hardening the systems and improving existing security controls.
