The Transportation & Mobility Special Interest Group (#SIG) is building a dedicated space within the FIRST community for collaboration across the #transportation and #mobility industry on cybersecurity challenges in the IT, OT, and #IoT space.
This practitioner-focused group will help organizations share best practices, improve coordination, and develop more unified approaches to incident response across connected transportation environments and mobility technologies.
The SIG also aims to advance standards and guidelines development while helping integrate transportation and mobility-focused incident response planning into the broader FIRST framework.
If you work in transportation security, OT/IoT security, incident response, infrastructure protection, or mobility technology, we encourage you to get involved and help shape this growing community!

Cyberangriffe auf kritische Infrastruktur klingt oft abstrakt. Bis plötzlich Wasserwerke betroffen sind. Der aktuelle Fall aus Polen zeigt: Angreifer greifen nicht mehr nur Daten an, sondern zunehmend physische Prozesse. Steuerungssysteme von Wasseraufbereitungsanlagen wurden manipuliert. Ursache laut Bericht: schwache Passwörter, direkte Internetanbindung und fehlende Segmentierung. #CyberSecurity #KRITIS #OTSecurity #Ransomware #Cybercrime #Wasserwerk
