TCP Layer Attack Prevention via Element Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current approaches lack adequate protections to ensure the security of network data in the TCP layer, making it vulnerable to attacks such as Distributed Denial of Service (DDoS).
Innovation Solution
A method is implemented where data packets are scanned to validate elements corresponding to communications protocol requests. Invalid requests are rejected, and validated requests are forwarded to servers, utilizing a client module in a datacenter to prevent transport layer attacks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If TCP layer performs peer validation based on IP and port information, then network communication can be established, but the system becomes vulnerable to manipulation attacks by nefarious actors
Solution Approach 1:
The patent applies preliminary action by implementing validation of TCP layer elements (IP addresses, port numbers, sequence numbers) before establishing peer validation. The system pre-checks these elements against expected formats and ranges, rejecting malformed data before it can be used for attacks. This proactive validation prevents manipulation attacks while maintaining reliable peer verification.
2Productivity
If the system floods with unwanted calls to disrupt services, then resource consumption increases, but legitimate requests are denied service
Solution Approach 1:
The patent implements preliminary action by validating TCP layer elements (IP addresses, port numbers, sequence numbers) before allocating system resources. Malformed or attack-related packets are rejected at the validation stage, preventing resource consumption from unwanted calls while ensuring legitimate requests receive timely service.
Solution Approach 2:
The patent introduces an intermediary validation mechanism that sits between incoming TCP packets and the target services. This intermediary layer checks IP addresses, port numbers, and sequence numbers against expected formats and behavioral patterns, filtering out malicious traffic before it reaches the service layer and preventing resource exhaustion from flooding attacks.
3Ease of operation
If current approaches are used without adequate protections, then network data transmission can proceed freely, but security of network data in the TCP layer is compromised
Solution Approach 1:
The patent introduces an intermediary validation layer that transparently checks TCP layer elements (IP addresses, port numbers, sequence numbers) without significantly impacting data transmission freedom. The validation occurs automatically in the background, allowing legitimate traffic to pass freely while blocking security threats, thus maintaining both ease of operation and data security.
Data Source
AI summary
A method comprises receiving one or more data packets corresponding to at least one communications protocol request, and scanning the one or more data packets to validate one or more elements corresponding to the at least one communications protocol request. The at least one communications protocol request is rejected in response to invalidating the one or more elements, and the at least one communications protocol request is forwarded to one or more servers in response to validating the one or more elements.
