Abstract: Environment type validation can provide a tamper-resistant validation of the computing environment within which the environment type validation is being performed. Such information can then be utilized to perform policy management, which can include omitting verifications in order to facilitate the sharing of policy, such as application licenses, from a host computing environment into a container virtual computing environment. The environment type validation can perform multiple checks, including verification of the encryption infrastructure of the computing environment, verification of code integrity mechanisms of that computing environment, checks for the presence of functionality evidencing a hypervisor, checks for the presence or absence of predetermined system drivers, or other like operating system components or functionality, checks for the activation or deactivation of resource management stacks, and checks for the presence or absence of predetermined values in firmware.
