Increasing networking in the production environment leads to a growing number of attack surfaces that need to be protected by appropriate security measures. The overarching goal of this paper is therefore to provide companies with an easy-to-use tool with which they can self-assess their own cybersecurity maturity level, identify vulnerabilities and, based on this, implement secure, digitally networked production themselves. The Fraunhofer IPT has therefore developed the "Production Security Readiness Check", which is presented in this article and the result of a study of 28 companies that have carried out the check is highlighted.enIndustry 4.0IT securityCybersecurityICS securityNetworked productionSecurity levelMaturity assessmentDDC::600 Technik, Medizin, angewandte Wissenschaften::650 Management, Öffentlichkeitsarbeit::658 Allgemeines ManagementDDC::600 Technik, Medizin, angewandte Wissenschaften::670 Industrielle Fertigungconference paper
