Toward Secure Web to ERP Payment Flows: A Case Study of HTTP Header Trust Failures in SAP Based Systems

Electronic banking portals often sit in front of enterprise resource planning (ERP) systems such as SAP, mediating payment requests between users and back end financial infrastructure. When these integrations place excessive trust in client supplied HTTP metadata, subtle design flaws can arise that undermine payment integrity. This article presents a retrospective, anonymized case study of an SAP based payment flow in which weaknesses in HTTP level validation allowed the front end application to incorrectly treat unpaid transactions as completed. Rather than provide a reproducible exploit, we abstract the scenario into a general vulnerability pattern, analyze contributing architectural decisions, and propose concrete design and verification practices for secure web to ERP payment processing. The discussion emphasizes formalizing payment state machines, strengthening trust boundaries, and incorporating regular security review into integration projects.

Microkernel-Based Web Architecture: Design & Implementation Considerations

In this vision paper I propose a middle-ground alternative between monolithic and microservice web architectures. After identifying the key challenges associated with microservice architectures, I revised the design of a microkernel-based web architecture, considering these challenges as well as recent architectural advancements. Next, I examined contemporary approaches to various self-* properties and explored how this new architecture could enhance them, including a modified version of the MAPE-K loop. Once the high-level design of the microkernel architecture was finalized, I evaluated its potential to address the identified challenges. Lastly, I reflected on several implementation aspects of the proposed work.
