Abstract: The invention provides a feedback control device and a feedback control method thereof. The feedback control device includes an enhancing circuit and a comparator. The enhancing circuit receives a feedback voltage corresponding to an output voltage of a DC-to-DC converter. In an embodiment, the enhancing circuit generates an enhanced feedback voltage based on the feedback voltage, and the comparator uses a comparison result between a reference voltage and the enhanced feedback voltage as a control signal to a feedback control terminal of the DC-to-DC converter. In another embodiment, the enhancing circuit generates an enhanced reference voltage based on the reference voltage, and the comparator uses a comparison result between the enhanced reference voltage and the feedback voltage as the control signal. In yet another embodiment, the comparator uses a comparison result between the enhanced reference voltage and the enhanced feedback voltage as the control signal.

Abstract: A method and system. A dataset is generated according to a code package. The code package includes an image file associated with a container for a tenant in a cloud environment. The dataset includes general information related to security aspects of the image file. The image file includes two or more image layers. A security indicator of the image file is extracted according to the dataset. A security level of the image file is determined by comparing the extracted security indicator of the image file with a security indicator of an authenticated image file. A vulnerability in the image file is identified based on the determined security level. In response to the vulnerability having been identified, the image file is updated with a patch that fixes the identified vulnerability. The patch includes a new image layer added to the two or more image layers in the updated image file.

Abstract: A method and system for code package. A dataset is generated according to a code package. The code package includes an image file associated with a container for a tenant. The dataset includes general information related to security aspects of the image file. The image file includes two or more image layers. Generating the dataset according to the code package includes: exporting an image layer from the image file; and obtaining a configuration file of the exported image layer as the dataset. In response to the vulnerability having been identified, the image file is updated with a patch that fixes the identified vulnerability. The patch includes a new image layer added to the two or more image layers in the updated image file.
