Methods, systems, and devices for protecting against abnormal computer behavior are described. The method may include monitoring a computer process related to an application running on a computing device of one or more computing devices, analyzing a database including a set of digital fingerprints, where a digital fingerprint of the set of digital fingerprints relates to the application, the digital fingerprint including an indication of a set of computer processes related to the application that are classified as normal computer processes for the application, determining that the computer process related to the application is an abnormal computer process based on analyzing, and performing a security action on the computing device to protect the computing device against the abnormal computer process based on the determining.

Application behavioral fingerprints

The disclosed computer-implemented method for creating program-specific execution environments may include (1) identifying a privileged software program to be executed on a client system in a program-specific execution environment, (2) establishing the program-specific execution environment by (a) determining that at least one process executing on the client system is not essential to operation of the privileged software program to be executed on the client system and (b) suspending execution of the non-essential process in response to identifying the non-essential process, and (3) initiating execution of the privileged software program in the program-specific execution environment. Various other methods, systems, and computer-readable media are also disclosed.

Systems and methods for creating program-specific execution environments

Security from malicious attack is provided for a user environment running in a virtualized environment by a virtual security appliance (VSA) running outside of the user environment, but on the same computer system as the user environment. For example, a VSA running in a virtual machine can provide security for a user environment running in a second virtual machine. The separation of the VSA from the user environment enhances the robustness of the VSA against malicious attacks seeking to disable/bypass the protections of the VSA, while avoiding the costs and complexities of a physical security appliance.
