Hotspot Host Device VPN Resource Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to protect resources accessible via a VPN tunnel to an authorized host device that is also operating as a hotspot, from other devices with inadequate security protections.
Innovation Solution
The solution involves a network traffic management system that establishes a VPN tunnel based on a successful compliance check, operates as a hotspot, and intercepts data packets from secondary devices. If the packets have a TTL value less than a default value, a security action is executed, such as dropping the packets or disconnecting the VPN tunnel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a host device establishes a VPN tunnel to access protected resources and simultaneously operates as a hotspot to provide Internet access to secondary devices, then connectivity and accessibility are improved, but security protection deteriorates because secondary devices without security compliance can access the VPN tunnel
Solution Approach 1:
The system performs security compliance checks on secondary devices before allowing them to access the VPN tunnel. By checking compliance status in advance (before potential security breaches can occur), the system prevents unauthorized access while maintaining legitimate connectivity. The compliance check is performed preliminarily when the secondary device attempts to connect to the hotspot, ensuring security is established before the VPN tunnel is accessed.
2Reliability
If security compliance checks are performed on all devices attempting to access the VPN tunnel, then security protection is improved, but device complexity and access control mechanisms increase
Solution Approach 1:
The host device acts as an intermediary between secondary devices and the protected resources. Instead of requiring direct compliance checks at the server level, the host device performs compliance verification locally before allowing access to the VPN tunnel. This intermediary approach simplifies the overall system architecture by consolidating security checks at the edge device level rather than requiring complex centralized authentication mechanisms for every access attempt.
3Reliability
If the host device monitors and intercepts data packets from secondary devices to enforce security compliance, then security protection is improved, but network traffic management complexity increases
Solution Approach 1:
The security monitoring and packet interception functionality is implemented locally at the host device rather than requiring centralized network traffic management. Each host device independently monitors its own outgoing traffic to protected resources and enforces security policies locally. This approach simplifies network-wide traffic management complexity by distributing security functions to individual host devices, where they can operate autonomously without requiring complex centralized coordination.

AI summary
Methods, non-transitory computer readable media, network traffic management devices, and network traffic management systems that protect resources that are accessible to a secondary device that is connected to a hotspot hosted by a host device that has an established VPN tunnel with a secure server storing the protected resources are illustrated. With this technology, a connection to a protected resource via a VPN tunnel is established by a host device based on a successful compliance check and the host device also simultaneously operates as a hotspot. The host device intercepts one or more data packets from a secondary device that is connected to the hotspot and in response to determining that the data packets have a TTL value that is less than a default value, the host device executes a security action with respect to the data packets.
