Heimdall: Towards Risk-Aware Network Management Outsourcing

Network and Distributed System Security (NDSS) Symposium 2025 · Day 1 · Network Security 1
In an era where operational efficiency and cost reduction drive business decisions, the outsourcing of IT services, particularly **network management**, has become a pervasive trend. This talk, "Heimdall: Towards Risk-Aware Network Management Outsourcing," presented by Yuejie Wang at the NDSS Symposium, addresses the critical security challenges inherent in this growing practice. The presentation introduces **Heimdall**, a novel framework designed to define, quantify, monitor, and respond to the risks associated with outsourcing network configuration troubleshooting. Given that the managed services market is projected to reach over $300 billion by 2025, with major players like Verizon, Fujitsu, and IBM offering such services, the security implications of granting third-party access to production networks are profound and increasingly complex.

Heimdall is legitimate academic systems work solving a real problem — third-party privileged access to production networks is genuinely underserved by existing tooling. The data-plane-leveraged RDG construction is the most interesting piece, and the quantitative asset-based risk model is a step up from flat command-privilege mappings. But this is a conference paper presentation, not a practitioner talk, and it shows: the depth stays at the model description level, the demo is entirely absent, and the results feel clean in a way that real messy production networks rarely are.
