Abstract: An optimization apparatus collects cyber attack information that is information related to a cyber attack, and system information that is information related to an entire system including a device that has received the cyber attack. Based on the collected cyber attack information and system information, the optimization apparatus identifies an attack route of the cyber attack, and extracts, as dealing point candidates, devices that are on the attack route and have an effective dealing function against the cyber attack. Subsequently, the optimization apparatus selects a dealing point from the extracted dealing point candidates by using optimization logic that has been set.

Abstract: A position detection apparatus includes a first irradiation section and a second irradiation section that irradiate an operation surface with detection light, an imaging section that captures an image of the operation surface, and a detection section that detects a pointed position pointed with a pointing element based on the captured image.

Instead, the position detection apparatus further includes an adjustment section that adjusts the intensity of the light emitted from at least one of the first irradiation section and the second irradiation section to adjust contrast between the pointing element and the operation surface to a value that exceeds a threshold.

Abstract: A cloud controller performs, when an attack on a VM in any of data centers in a system is detected, setting of NAT of a private IP address of a VM(A), for a boundary router of each data center other than a data center that the VM(A) belongs to, the VM(A) being a victim. Next, the cloud controller performs setting for a redirecting device in the same data center as the VM(A), such that the redirecting device redirects access from a user terminal to a host under a boundary router of any of the respective data centers other than the data center. Thereafter, the cloud controller changes a private IP address of the VM(A) in a NAT setting of a boundary router of the data center to a private IP address of the redirecting device.
