Don’t be hoisted by your own petard

In the closing stages of Victor Hugo’s Les Misérables the chief character, Jean Valjean, while carrying another key character seeks to evade the authorities. He does so by traveling through the sewers of Paris, while the search for him and other rebels is focused on the streets above him. In this way Valjean is able to use a critical but commonly forgotten part of the maintenance infrastructure of the city against the city itself.

As I reviewed the research into the Transport Management System (TMS) carried out by the world renowned Research Labs here at Onapsis the parallels of how organizations ignore their Transport Management System when considering the risk and attack surface of their SAP systems and the method employed by Valjean to evade capture were very striking to me. In both cases we have a system that has equal access to all points on the network, from Dev to QA and Productive systems.

The research team has boiled all the relevant risk information and best practices to secure the Transport Management System in this SAP Security In-Depth (SSID) publication. Understanding how to secure your TMS becomes critical when you understand the interconnected nature of a Transport Domain, and the level of access an attacker could gain to the entire landscape if they are able to get a foothold to just one system within the Transport Domain.

This SSID publication is just one in an ongoing series of educational publications researched and produced by Onapsis; all with the goal of providing SAP customers with the information they need to both understand the risks inherent in certain components and the best practices by which to manage these risks.
