Malicious mobile code runtime monitoring system and methods

摘要

Protection systems and methods provide for protecting one or more personal computers (“PCs”) and/or other intermittently or persistently network accessible devices or processes from undesirable or otherwise malicious operations of Java TN applets, ActiveX™ controls, JavaScript™ scripts, Visual Basic scripts, add-ins, downloaded/uploaded programs or other “Downloadables” or “mobile code” in whole or part. A protection engine embodiment provides for monitoring information received, determining whether received information does or is likely to include executable code, and if so, causes mobile protection code (MPC) to be transferred to and rendered operable within a destination device of the received information. An MPC embodiment further provides, within a Downloadable-destination, for initiating the Downloadable, enabling malicious Downloadable operation attempts to be received by the MPC, and causing (predetermined) corresponding operations to be executed in response to the attempts.

主权项

1. A method for protecting a computer from malicious downloadables, comprising:
receiving, by a first computer, an incoming downloadable, the downloadable including a security profile including a list of suspicious instructions that was attached thereto by a second computer; extracting the security profile from the received downloadable; comparing the security profile with a security policy to determine if the downloadable violates the security policy; and taking an additional action related to execution of the downloadable if the downloadable violates the security policy.
