DeepSec 2024 Talk: Why NIS2 Implementation often fails in Industrial Areas – Michael Walser

Sanna/ November 12, 2024/ Conference/ 0 comments

Why do most projects preparing for NIS2 fail in practice? Many affected companies complain about the requirements of EU Directive 2022/2555, which are too unspecific and technically difficult to implement. Excessive demands are spreading. Companies affected are uncertain because of the evaluation of the actual implementation, unlike ISO security certification (e.g. ISO27001/ISO62443). The results are often unsatisfactory despite the sometimes massive investment in costs and personnel resources. An Excel spreadsheet or a Visio drawing itself does nothing to change the resilience of KRITIS or industrial facilities against cyber-attacks in practice. We focus on industrial customers and their OT infrastructure, using anonymized, real-world examples to show the challenges in practice and offer examples of solutions to prevent repeating past mistakes. The first steps do not have to cost a lot of money or tie up

DeepSec 2022 Talk: Faking at Level 1 – How Digital Twins Save Your PLCs – Thomas Weber

Sanna/ August 29, 2022/ Conference

Every year, many big and small incidents in industrial environments, like power plants, factories, or food supply, find their way into newspapers. All those affected industries are backed by highly branched and historically grown Operational Technology (OT) networks. A sizeable portion of such incidents would have been avoidable, if network segmentation was done correctly and patches for user devices (not always possible in OT) were installed.Despite such known problems, that also lead to the compromise of traditional IT networks, a bunch of unknown vulnerabilities are unfortunately also present in OT infrastructure. OT in modern factories contains of networked (and smart) devices, especially on level 1, also called the control level, of the Purdue model. Devices, like PLCs, industrial router/switches, data diodes, and more, cannot be easily tested if they are in use by the
