A system is provided for computing system configuration file state mirroring on peer computing devices. In particular, the system may identify and select a computing device containing a configuration file to be protected by the system. The system may then store various portions of the configuration file across a plurality of trusted peer computing devices. Once the baseline values for the configuration file have been established, the system may, upon detecting any unintentional or unauthorized changes to the configuration file, initiate a reconstruction process to restore the configuration file to its baseline values. In this way, the system provides a way to maintain the integrity of protected configuration files of computing devices within the network.
