Autonomous systems are reshaping modern enterprises and introducing new challenges for information security and digital trust. This session explores the relationship between autonomous systems, information security and digital identities. By examining a concrete threat scenario, it highlights how manipulated algorithms or falsified identities can disrupt system behaviour, compromise core technologies and impact safety, integrity and operational continuity. The presentation also shows how strong, controlled and managed digital identities enable the security of autonomous systems and help maintain confidentiality, integrity and availability across connected production environments.
