Abstract

A method in one example implementation includes intercepting a request associated with an execution of an object (e.g., a kernel module or a binary) in a computer configured to operate in a virtual machine environment. The request is associated with a privileged domain of the computer that operates logically below one or more operating systems. The method also includes verifying an authorization of the object by computing a checksum for the object and comparing the checksum to a plurality of stored checksums in a memory element. The execution of the object is denied if it is not authorized. In other embodiments, the method can include evaluating a plurality of entries within the memory element of the computer, wherein the entries include authorized binaries and kernel modules. In other embodiments, the method can include intercepting an attempt from a remote computer to execute code from a previously authorized binary.
