Abstract
A computer implemented method includes generating a first cryptographic hash based on at least one setting associated with an operating system at a first time, storing the first cryptographic hash as a first bit string, generating a second cryptographic hash as a second bit string, wherein the second cryptographic hash is based on the at least one setting associated with the operating system at a second time, determining that a setting associated with the operating system has changed and that the setting change was made outside of the operating system based on a comparison of the first and second bit strings, and if the setting change was made outside of the operating system, setting the setting to a default value.
