Dynamic cloud configuration changes based on advanced persistent threat detection
Techniques are described for dynamic cloud configuration changes based on a computing attack detection. An example method can include a device receiving a message that a metric collected from a processor has exceeded a threshold, the processor being an element of a first node, the first node, exceeding the threshold being indicative of a computing attack. The device can transmit a first instruction over the network to transition a second processor from the first node to a second node. The device can transmit a second instruction over the network to suspend the first node from receiving a workflow request. The device can determine whether the processor is a victim of the attack. The device can transmit the determination of whether the processor is the victim of the attack. The device can receive a second message that the attack has been mitigated.
