The computer-based method of claim 15 wherein the Downloadable includes program script.

A system for managing Downloadables, comprising: a receiver for receiving an incoming Downloadable; a Downloadable identifier for performing a hashing function on the incoming Downloadable to compute an incoming Downloadable ID; a database manager for retrieving security profile data for the incoming Downloadable from a database of Downloadable security profiles indexed according to Downloadable IDs, based on the incoming Downloadable ID, the security profile data including a list of suspicious computer operations that may be attempted by the Downloadable; and a transmitter coupled with said receiver, for transmitting the incoming Downloadable and a representation of the retrieved Downloadable security profile data to a destination computer, via a transport protocol transmission. view more

A method comprising: receiving by an inspector a Downloadable; generating by the inspector a first Downloadable security profile that identifies suspicious code in the received Downloadable; and linking by the inspector the first Downloadable security profile to the Downloadable before a web server makes the Downloadable available to web clients. view more

The method of claim 1, wherein the Downloadable includes a JavaScript.TM. script.

The system of claim 15, wherein the first rule set includes a list of suspicious operations.

A system for generating a Downloadable ID to identify a Downloadable, comprising:</claim-text> a communications engine for obtaining a Downloadable that includes one or more references to software components required to be executed by the oadable; and an ID generator coupled to the communications engine that fetches at least one software component identified by the one or more references, and for performing a hashing function on the Downloadable and the fetched software components to generate a Downloadable ID. view more

A computer-readable storage medium storing program code for causing a computer to perform the steps of:</claim-text> obtaining a Downloadable that includes one or more references to software components required to be executed by the Downloadable; ing at least one software component identified by the one or more references; and performing a hashing function on the Downloadable and the fetched software components to generate a Downloadable ID. view more

A system for protecting a computer from dynamically generated malicious content, comprising: a content processor (i) for processing content received over a network, the content including a call to a first function, and the call including an input, and (ii) for invoking a second function with the input, only if a security computer indicates that such invocation is safe; a transmitter for transmitting the input to the security computer for inspection, when the first function is invoked; and a receiver for receiving an indicator from the security computer whether it is safe to invoke the second function with the input. view more

A computer-based method, comprising the steps of: receiving an incoming Downloadable; deriving security profile data for the Downloadable, including a list of suspicious computer operations that may be attempted by the Downloadable; and storing the Downloadable security profile data in a database. view more

A system for managing Downloadables, comprising: a receiver for receiving an incoming Downloadable; a Downloadable scanner coupled with said receiver, for deriving security profile data for the Downloadable, including a list of suspicious computer operations that may be attempted by the Downloadable; and a database manager coupled with said Downloadable scanner, for storing the Downloadable security profile data in a database. view more

The system of claim 10 wherein the Downloadable includes program script.

The system of claim 10 wherein said Downloadable scanner comprises a disassembler for disassembling the incoming Downloadable.
