  • Publication number: 20250016220
    Abstract: This application relates to a method and apparatus for processing a security service, and to a device, a storage medium, and a program product related to the technical field of network security. The method includes: receiving a Honeypot service deployment request transmitted by a first device of a network content provider, the Honeypot service deployment request being configured to indicate a probe service type and a Honeypot service type; establishing, based on the Honeypot service type, a Honeypot service in a cloud corresponding to target network content, the target network content being network content provided by the network content provider; and establishing, based on the probe service type, a probe service of the network content provider. In this disclosure, a Honeypot service of the network content provider may be automatically created in the cloud, thereby improves deployment efficiency of a Honeypot system.

  • Patent number: 8792258
    Abstract: An apparatus for coupling a switching mode power supply (SMPS) controller to a rectified line voltage. The apparatus includes a high-voltage startup transistor configured to provide a charging current during a startup phase of the SMPS controller and to provide substantially no current during a normal operation phase of the SMPS controller. A switch coupled to the high-voltage startup transistor. The switch receives a control signal from the SMPS controller, for turning off the switch during the startup phase and turning on the switch during the normal operation phase. A biasing device is connected in series with the switch and maintains the startup transistor in an off state when the SMPS controller is in the normal operation phase. A standby current in the apparatus is substantially lower when the SMPS controller is in the normal operation phase than the charging current in the apparatus when the SMPS is in the startup phase.
