Abstract: A method includes, in response to receiving an email message, detecting one or more artifacts within an email message, wherein each of the artifacts is associated with a payload; for each artifact, generating, a descriptor object representing the artifact that does not include the payload, so that the processor is prevented from accessing the payload via the descriptor object; and at least one payload button based on the payload associated with the artifact for causing the payload to be transmitted to an external system for analysis of the payload; and presenting an artifact dashboard in a graphical user interface (GUI) rendered on a display of the email security system, the artifact dashboard displaying, for each artifact, the descriptor object representing the artifact and the at least one payload button based on the payload associated with the artifact.

Abstract: Disclosed are a method and system of tracking real time use of I/O control blocks on a processing unit basis, in a multiprocessing system, such that in the case of a processing unit failure, a list accurately and concisely identifies the control blocks that need to be recovered. This eliminates the need to scan all the I/O control blocks, greatly reducing the overall system recovery time and minimizing impact to the rest of the running system. The preferred embodiment of the invention uses a task control block structure to record which I/O control blocks are in use by each Processing Unit. Also, the lock word structure defined in the I/O control blocks is provided with an index back into the task control block to facilitate managing the task control block entries.
