Platform Security: "Insecure SAP system interfaces: an underestimated risk."
-------------------------------------------------------------------------------------
How confident are you that your SAP systems are sufficiently protected against cyberattacks? In our experience, it's far too often the case that companies fail to pay the requisite attention to analyzing and securing their SAP system interfaces. These include RFC connections, SAP Gateway, and extended ST01 traces, along with considerations of their relevance, criticality, and potential defects.
As you take the steps necessary to secure your landscape, the suite module SAST Interface Management can provide you with optimal support. It's capable of evaluating multiple systems, creating a comprehensive interface overview in graphical or tabular format, and categorizing the flaws it finds.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
