Abstract:
1. A computer-implemented method comprising: receiving one or more change approval packages at a first computer system from a second computer system including a configuration management database, each of the change approval packages including authorized change identification data that identifies one or more authorized changes of at least one configuration item in the first computer system, and wherein each change approval package is a result of an approved request for change that is stored in an authorized configurations area of the configuration management database prior to being received at the first computer system; storing the received authorized change identification data in an authorization configuration storage area associated with the first computer system; in response to the storing, receiving a change package at the first computer system, the change package including a change to at least one configuration item in the first computer system and metadata that identifies the change; comparing, by the first computer system, the received metadata with the stored authorized change identification data; installing the change on the first computer system in response to the comparison revealing that the received metadata matches one of the stored authorized change identification data; and rejecting the change in response to the comparison revealing that the received metadata does not match any of the stored authorized change identification data, wherein the rejecting prevents unauthorized application of the change package to the first computer system before the change package is applied.
