CYBERSECURITY HARDENING FOR NETWORKED SYSTEMS

A computer-readable medium contains cybersecurity configuration settings (CCS) generating file(s) including instructions when executed cause a processor of a computer located at a node in a networked system having computers including at least one computer system class to generate CCS. The CCS generating file includes group policy objects (GPOs) applicable to all computers, policy setting scripts that are applicable to <all the computer s, and group policy definition files which provide a policy setting library for the computer class. Execution of the CCS generating file at the node automatically generates the CCS for cybersecurity protection of the node. The computer class can include computer classes that include ≥2 different operating systems, and there can be a CCS generating file for each computer class. The CCS generating file can be a single multi-class CCS generating file that includes a plurality of CCS generating files.
