Abstract
A system already on a network may be analyzed when the system takes an action or may be periodically reviewed. The analysis of the system may include the creation of an environment hash for the system, which is a representation of the configuration (e.g., hardware, software, or the like) of the system, and a comparison with hash requirements. The hash requirements may be stored authorized hashes, stored unauthorized hashes, past hashes for the same system, hashes for other systems with the same or similar configurations, or the like. When the environment hash of the system meets hash requirements, the system may be allowed to continue to operate on the system or may be allowed to take the action on the network. When the hash of the system fails to meet a hash requirement, the system may be isolated from the network and investigated for a non-compliant configuration.
