This volume presents revised selected papers from two workshops focused on critical aspects of computer security: industrial control systems and security/privacy requirements engineering. The book compiles research from the 4th International Workshop on the Security of Industrial Control Systems and Cyber-Physical Systems (CyberICPS 2018) and the Second International Workshop on Security and Privacy Requirements Engineering (SECPRE 2018), both held in conjunction with ESORICS 2018. The CyberICPS papers address threats, vulnerabilities, and detection/response strategies for cyber-physical and industrial control systems, while the SECPRE papers focus on assurance, evaluation, elicitation, and modeling of security and privacy requirements.

This collection of revised selected papers offers a focused look at contemporary challenges in computer security, specifically within industrial control systems and the crucial area of requirements engineering for security and privacy. The inclusion of papers from both CyberICPS and SECPRE workshops suggests a comprehensive approach to understanding and mitigating risks in these specialized domains. The selection process, which involved rigorous review of submissions, indicates a high standard for the presented research. The content is likely to appeal to researchers, practitioners, and policymakers involved in securing critical infrastructure and developing robust security and privacy protocols.
