Autonomous Server Powerdown on Network Connectivity Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security measures for remotely-managed computer servers are inadequate when network connectivity is compromised, as control plane servers may be unable to robustly respond to threats due to differing physical locations and less secure internet communication.
Innovation Solution
Computer servers are equipped with an agent that autonomously detects loss of network connectivity and initiates a power-down sequence, including disabling volatile memory to protect data, especially when communication with a remote control plane server is disrupted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If control plane servers remotely monitor data plane servers over the public internet, then server management flexibility is improved, but security robustness deteriorates due to less secure internet communication compared to intra-location communication
Solution Approach 1:
The system performs preliminary actions by implementing autonomous threat response capabilities directly on data plane servers before remote control plane servers can respond. The autonomous agent continuously monitors for threats and can immediately initiate countermeasures such as isolating affected systems or executing security protocols without waiting for remote instructions, thereby maintaining security robustness while enabling remote management flexibility
Solution Approach 2:
An autonomous security agent acts as an intermediary between the data plane servers and remote control plane servers. This local intermediary enables secure autonomous operation while maintaining communication channels with remote administrators, allowing the system to benefit from both remote management flexibility and local security decision-making capability
2Adaptability or versatility
If control plane servers are located in a different physical location from data plane servers, then operational independence is improved, but response effectiveness deteriorates when physical security of data plane servers is suspect
Solution Approach 1:
The data plane servers are equipped with autonomous agents that enable self-service security operations. These agents can independently detect threats, assess risks, and execute countermeasures without requiring physical presence or direct intervention from control plane servers, thereby maintaining response effectiveness even when control plane servers are located in different physical locations
Solution Approach 2:
The system implements preliminary security measures by pre-configuring autonomous agents with threat detection and response capabilities on data plane servers. This allows the servers to independently respond to security threats without requiring real-time coordination with remotely-located control plane servers, maintaining response effectiveness while preserving operational independence
3Reliability
If autonomous threat response is implemented on data plane servers, then security response time is improved, but device complexity increases due to additional monitoring and response mechanisms
Solution Approach 1:
The autonomous agent is designed as a universal multi-functional component that combines threat monitoring, analysis, and response capabilities in a single integrated system. This multi-functionality reduces overall system complexity compared to having separate dedicated systems for each security function, while still achieving rapid security response times
Solution Approach 2:
The system merges threat detection, analysis, and response functions into a single autonomous agent running on each data plane server. This consolidation reduces the complexity of having multiple separate systems while enabling rapid security responses, as the agent can immediately act on detected threats without coordination delays

AI summary
A system and method executed by a computer server include determination that the computer server has lost network connectivity and, in response to the determination that the computer server has lost network connectivity, disabling of power to a volatile memory of the computer server. Determining that the computer server has lost network connectivity may include transmission of data to an external system and determination that a response to the data was not received from the external system. Disabling of power to the volatile memory may include transmission of a request to an operating system of the system to initiate a power-down sequence of the system.
