Parce que… c'est l'épisode 0x610! Shameless plug 12 au 17 octobre 2025 - Objective by the sea v8 10 au 12 novembre 2025 - IAQ - Le Rendez-vous IA Québec 17 au 20 novembre 2025 - European Cyber Week 25 et 26 février 2026 - SéQCure 2026 Description Introduction et contexte Dans cet épisode technique du podcast, les participants explorent les défis complexes de l'implémentation des technologies de télémétrie de sécurité dans les environnements de technologie opérationnelle (OT). Ils abordent particulièrement la transposition des concepts familiers du monde IT, comme les EDR (Endpoint Detection and Response), XDR (Extended Detection and Response) et NDR (Network Detection and Response), vers l'univers industriel. Les fondements de la télémétrie de sécurité Les technologies de détection et de réponse reposent sur deux piliers principaux : la détection (génération de télémétrie intelligente) et la réponse (capacité d'intervention automatisée). Du côté IT, ces systèmes permettent d'intervenir sur les terminaux en les isolant ou en bloquant certaines actions, tandis qu'au niveau réseau, ils peuvent bloquer le trafic identifié comme malveillant. Cette approche, bien maîtrisée en IT, pose des défis considérables lorsqu'elle est transposée dans les environnements OT. Les défis spécifiques à l'environnement OT L'installation d'un EDR sur un automate industriel s'avère impossible, contrairement à un poste Windows traditionnel. Les équipements industriels génèrent une télémétrie primaire et limitée, rendant difficile l'extraction de signaux de sécurité pertinents. Les experts recommandent de se concentrer sur les actifs plus évolués fonctionnant sous Windows ou Linux, car la majorité des attaquants privilégient ces plateformes familières plutôt que les systèmes industriels propriétaires. Cette approche s'appuie sur la “théorie du 99%”, qui stipule que les actifs IT ont une capacité de défense autonome contrairement aux actifs OT. Les attaques sophistiquées ciblant directement les systèmes industriels, comme Stuxnet ou Triton, demeurent exceptionnelles avec seulement quatre cas documentés en vingt ans. La plupart des incidents se limitent au niveau 3 du modèle de référence industriel, où se trouvent les serveurs et stations de travail Windows. L'enjeu patrimonial et la durée de vie des équipements L'environnement OT présente une caractéristique unique : la longévité exceptionnelle des équipements. Contrairement au monde IT où les systèmes sont régulièrement renouvelés, les installations industrielles peuvent fonctionner pendant 40 ans. Cette durée de vie étendue s'explique par les coûts élevés des équipements (plusieurs millions par pièce) et leur cycle de vie utile prolongé, particulièrement dans des secteurs comme la santé. Cette situation crée des défis de sécurité considérables, certaines installations fonctionnant encore sur des systèmes obsolètes comme Windows 3.11 ou NT4. Les organisations développent parfois des solutions de contournement, comme l'isolement par air gap et la réinstallation périodique des stations de travail pour gérer les infections persistantes. Complexité d'implémentation des EDR en OT L'implémentation d'EDR dans l'environnement OT nécessite une analyse de risque approfondie. Le confinement automatique, fonction standard des EDR, peut s'avérer catastrophique dans un contexte industriel. Les experts rapportent des incidents où un fichier de programmation d'automate (ladder logic) a été incorrectement identifié comme malveillant, provoquant le confinement automatique d'un serveur critique. La configuration des EDR en OT exige une adaptation minutieuse, notamment la désactivation des fonctions de réponse automatique. De plus, ces systèmes demandent des ressources significatives et ne peuvent pas être déployés sur des serveurs déjà saturés ou ayant des capacités limitées, situation fréquente dans l'industrie. Défis de la télémétrie personnalisée Contrairement aux systèmes IT où les événements sont standardisés, les automatismes industriels génèrent une télémétrie sur mesure. Il existe peu d'experts capables d'interpréter les signaux industriels pour détecter des anomalies sécuritaires. Cette analyse nécessite généralement l'expertise d'ingénieurs de procédé familiers avec les systèmes spécifiques. Les solutions de surveillance passive existent mais requièrent un investissement considérable en configuration et en compréhension de l'environnement. L'établissement d'une baseline de trafic normal peut prendre près d'un an de travail pour atteindre un niveau de visibilité comparable à celui obtenu en IT. Architecture et cloisonnement réseau Le transfert des signaux OT vers les consoles IT pose des défis architecturaux majeurs. Les environnements industriels sont généralement cloisonnés, nécessitant la création de pipelines d'ingestion de données complexes. Ces systèmes de relais permettent de traverser les barrières réseau tout en maintenant la sécurité, mais rendent les projets de visibilité particulièrement laborieux. La remontée des signaux vers une console de sécurité unifiée nécessite souvent une infrastructure dédiée côté OT, créant un “réseau dans le réseau” pour observer les systèmes cloisonnés depuis l'extérieur. Contraintes des fournisseurs et garanties Les fournisseurs d'équipements industriels imposent souvent des restrictions strictes sur les solutions de sécurité autorisées. Dans les installations récentes sous garantie, seules certaines solutions approuvées peuvent être déployées. Le non-respect de ces contraintes peut entraîner l'annulation de garanties couvrant parfois 10 à 15 ans d'exploitation. Cette situation oblige les organisations à valider toute solution de sécurité en laboratoire avant le déploiement, avec une représentation miniature de l'environnement de production. Certains éditeurs d'EDR montrent peu d'affinité avec les environnements cloisonnés, privilégiant des approches IT traditionnelles. Évolution vers le cloud et nouveaux paradigmes L'industrie OT évolue progressivement vers des solutions cloud, même pour les scanners passifs traditionnellement conçus pour des environnements isolés. Cette transition soulève des questions sur l'ouverture contrôlée d'accès Internet dans les couches basses du modèle de Purdue, remettant en question l'isolement total historiquement privilégié. Les solutions modernes nécessitent un flux continu de renseignements sur les menaces pour détecter efficacement les menaces émergentes. Le transport traditionnel de signatures s'avère trop lent face à l'évolution rapide des cybermenaces. Perspectives et recommandations Les experts recommandent de se concentrer sur la consolidation des journaux Windows et des événements SNMP comme point de départ pour améliorer la visibilité. Cette approche pragmatique permet d'obtenir rapidement des gains significatifs dans des environnements actuellement dépourvus de toute visibilité sécuritaire. L'implémentation réussie de ces technologies requiert une collaboration étroite entre les équipes IT et OT, traditionnellement en tension. La cybersécurité en OT doit être perçue comme un mode de défaillance supplémentaire à surveiller, au même titre que les paramètres opérationnels traditionnels. Conclusion L'adaptation des technologies xDR aux environnements OT représente un défi multifacette nécessitant une approche sur mesure. Bien que les concepts IT puissent servir de base, leur transposition directe s'avère inadéquate. Le succès dépend d'une compréhension fine des contraintes industrielles, d'une analyse de risque rigoureuse et d'une architecture respectant les impératifs de sécurité et de continuité opérationnelle. L'évolution vers une visibilité sécuritaire complète en OT demeure un processus long et complexe, mais nécessaire face à l'évolution des menaces cybernétiques.

People who know Alex Hartman realize that he tends to be way ahead of the pack. Alex is typically just beyond the cutting edge of technology implementation. That often makes his comments hard to understand. But when you get to know Alex and understand his ideas and concerns, they usually do make very good sense. He’s also good at “breaking things”, revealing weak points in design. Today we’re discussing people, skills, and the uncertain future of talent sourcing. Alex has some real concerns and ideas about this. In his position at Wisconsin Public Media, Alex is hands-on with basic audio tech, but also data centers and managing fleets of equipment, computing, and sometimes people.

Can a team of engineers resolve thousands of engineering trouble tickets each month, and do it efficiently and keep with good engineering practice? iHeartMedia is doing it and Mike Sprysenski is leading that team. From an office in Orlando, Mike Spry and a team of radio engineers and IT professionals resolve engineering issues at nearly 900 radio stations, keeping those stations on-the-air. Many issues are even handled preemptively, before they affect what the public is hearing over the air or online. Chris Tarr and Kirk Harnack discuss this approach with Mike on this episode of TWiRT.

We receive our audio editor but first of all DataCenter guru Kris Vandecruys. He tells us about SAN and the storage technologies, FiberChannel, the difference between NAS and SAN as well as the time where an SNMP monitoring script killed the whole datacenter.

AI and machine learning are finally being applied to networking in meaningful ways. On today's sponsored show we talk with Selector about its AIOps platform, which ingests networking logs, flows, configurations, SNMP, and other telemetry to detect patterns, spot problems, and provide contextual insights to help network engineers do their jobs better. We speak with Selector about what it is, how it works, and concrete use cases.

Interoperability - what does that mean? After this 1-hour conversation with Robbie Green and Chris Tarr, I would say it means “controlling or checking on one device by using another device or system”. Scaled up intelligently, it implies having control and understanding of complex systems from a single location, or doing so automatically. So, rather than separately checking on an automation system, an audio processor, an audio router, a satellite receiver, a transmitter, or a security system, these individual systems can connect meaningfully to a central monitoring and control (“M&C”) system and/or to each other as appropriate. GPIO is a low-bar baseline for interoperability. Serial control, RS-422, and CanBUSS moved us forward, but a variety of TCP/IP protocols, including SNMP, have brought us to a good level of general interoperability if we’re willing to do the work and research to implement them. These ideas have motivated Robbie Green and Chris Tarr to implement interoperabilities that make broadcast operations more reliable, stable, and convenient. Show Notes:Robbie mentioned the LANTRONIX UDS2100 as a good Serial Device ServerWe mentioned live, on-line demos of some Inovonics devices, which are also interoperableConnect SNMP to other protocols with these...https://www.controlbyweb.com/x600m/Robbie’s example of vMix TCP integration - https://www.vmix.com/help26/TCPAPI.htmlMessaging on various display platforms, like Paravel's WallTime Guest:Robbie Green - Product Manager, Communication Products at Telos Alliance Hosts:Chris Tarr - Group Director of Engineering at Magnum.MediaKirk Harnack, The Telos Alliance, Delta Radio, Star94.3, & South Seas BroadcastingFollow TWiRT on Twitter and on FacebookTWiRT is brought to you by:Nautel brings you Transmission Talk Tuesday Discussions.

Today we chat with Tom Nadeau, the CTO of Spirent. Tom shares his non-traditional career path, from his early days doing AI in undergraduate and autonomous robots cleaning the underwater side of boats, to his current role at Spirent, where he works on some cool projects like satellite technology and rocket science.Tom also talks about how he moved over to Networking after AI didn't work out, how he bumped into the inventor of SNMP, and had one of the hardest interviews of his career.He also shares his insights on how to navigate difficult situations, how to make the best of it when things don't work out, and how to build relationships even after making mistakes.- One of the secrets to being successful at the IETF is the people that roll their sleeves up and do the work.  A lot of people are going to want to talk about things, they're going to want to tell you to do things. That's fine, but the most successful people are the ones that sit down and just write it down, build it, and get it going. - Tom's Links:  TwitterLinkedIn  The Net Podcast--Thanks for being an imposter - a part of the Imposter Syndrome Network (ISN)!
