Efficient implementation of honeypot devices to detect wide-scale network attacks
The present disclosure generally relates to enabling efficient implementation of honeypot devices in a honeypot service environment. Each honeypot device can be implemented as a virtualized device, executing software modified from a production version of a device such that interactions with the honeypot device closely match interactions with a production device. By using virtualization, each honeypot device can be reset to a known good state when a potential security breach occurs. Because network-based attacks are often wide-spread, the honeypot service environment can deduplicate attacks that occur at a large number of devices, discarding duplicate attack traffic to reduce overall load on the environment. While deduplication can be inappropriate for production environments (given the corresponding data loss), deduplication in a honeypot environment can reduce load while still enabling detection of a network attack. |

Automated on call and ad hoc access to restricted resources
Complex cloud-based system with many different entities, e.g., servers, clients, databases, firewalls, other machines, etc. often require on call engineers to be available to help with maintenance, emergencies, and other tasks. Sometimes ad hoc access is required when on call engineers are unable to resolve a particular issue. Organizations that manually manage access to on call and ad hoc engineer access, may do so relatively easily if they are a smaller organization. But, for larger or more complex environments, manual processes represent a significant burden. An alternative is automatically grant and revoke access. For example, if a vendor tracks your on call engineers, on call statuses may be identified to automatically grant access while on call. For ad hoc access, a requestor may request temporary access, and if valid, access may also be automatically granted for a desired time period. Automation frees valuable limited resources for other tasks. |

Magnet stack and motor
In a magnet stack, an eddy current channel is cut off by an insulating layer in an insulating region of facing surface regions of the pair of magnets. Meanwhile, in a conducting region of the facing surface region of the pair of magnets, electrons can move between the pair of magnets via a conductor, and heat can be exchanged between the pair of magnets by the movement of electrons. Therefore, in the magnet stack, by cutting off the eddy current channel in the insulating region of the facing surface region of the pair of magnets, the degradation in magnet performance is suppressed and the cooling efficiency of the magnet is enhanced in the conducting region. |
