SECURING INDUSTRIAL SYSTEMS: IEC 62443 ASSESSMENT AND REMEDIATION

In the context of Industry 4.0, the growing interconnection of OT systems has increased exposure to cyber threats with impacts on production, assets, and operator safety. Industrial cybersecurity therefore requires specific approaches that go beyond physical protection and operational continuity alone. This thesis analyzes and proposes a structured Incident Response model for OT environments, covering the entire incident management cycle in order to ensure resilience and business continuity.
