Computer immune system and method for detecting unwanted code in a computer system

An automated analysis system detects malicious code within a computer system by generating and subsequently analyzing a behavior pattern for each computer program introduced to the computer system. Generation of the behavior pattern is accomplished by a virtual machine invoked within the computer system. An initial analysis may be performed on the behavior pattern to identify infected programs on initial presentation of the program to the computer system. The analysis system also stores behavior patterns and sequences with their corresponding analysis results in a database. Newly infected programs can be detected by analyzing a newly generated behavior pattern for the program with reference to a stored behavior pattern to identify presence of an infection or payload pattern.

Dynamic virtual machine service provider allocation

A server receives a request for a service. The server determines if a virtual machine already exists that offers the service. If so, the server returns an identifier of the virtual machine to the requesting client so that the client may access the service from the virtual machine. Otherwise, the server attempts to create an image of a virtual machine offering the service. If successful in creating the image, the image is installed as a new virtual machine in a host machine, and the server returns an identifier of the newly created virtual machine to the client.

Computer immune system and method for detecting unwanted code in a P-code or partially compiled native-code program executing within a virtual machine

An automated analysis system identifies the presence of malicious P-code or N-code programs in a manner that limits the possibility of the malicious code infecting a target computer. The target computer system initializes an analytical virtual P-code engine (AVPE). As initialized, the AVPE comprises software simulating the functionality of a P-code or intermediate language engine as well as machine language facilities simulating the P-code library routines that allow the execution of N-code programs. The AVPE executes a target program so that the target program does not interact with the target computer. The AVPE analyzes the behavior of the target program to identify occurrence of malicious code behavior and to indicate in a behavior pattern the occurrence of malicious code behavior. The AVPE is terminated at the end of the analysis process, thereby removing from the computer system the copy of the target program that was contained within the AVPE.

Optimizing application performance on virtual machines automatically with end-user preferences

A virtual machine management / monitoring service can be configured to automatically monitor and implement user-defined (e.g., administrator-defined) configuration policies with respect to virtual machine and application resource utilization. In one implementation, the monitoring service can be extended to provide user-customized alerts based on various particularly defined events that occur (e.g., some memory or processing threshold) during operation of the virtual machines and / or application execution. The user can also specify particularly tailored solutions, which can include automatically reallocating physical host resources without additional user input on a given physical host, or moving / adding virtual machines on other physical hosts. For example, the monitoring service can be configured so that, upon identifying that a virtual machine's memory and processing resources are maxed out and / or growing, the monitoring service adds memory or processing resources for the virtual machine, or adds a new virtual machine to handle the load for the application program.
