IP Address Filtering via URL Resolution

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods for blocking malicious Internet content are manual, time-consuming, and often result in devices accessing harmful content before identification, as they rely on URL blocking rather than proactive IP address filtering.

Innovation Solution

Implementing IP address filtering that uses web crawlers to identify suspicious URLs, resolve them to IP addresses, and create a suspicious IP address list for proactive blocking or warning, based on context and threat ranking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual URL blocking is used, then users can control what content is accessed, but the process is time-consuming and devices may access harmful content before identification

Engineering Contradiction:

Improvesecurity protectionVSAvoidtime to identify and block malicious content

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by proactively identifying and blocking malicious IP addresses before users can access harmful content. Web crawlers continuously scan the internet to find suspicious URLs, resolve them to IP addresses, and add them to block lists in advance, preventing access before any harm occurs to the device.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system provides self-service by automatically detecting, analyzing, and blocking malicious content without requiring manual user intervention. The automated web crawling, IP resolution, and block list generation processes occur autonomously, eliminating the need for users to manually monitor and block threats.

Inventive Principle:

Principle #25Self-service

2Extent of automation

If automated web crawling and IP resolution is implemented, then proactive blocking of malicious content is achieved, but system complexity increases

Engineering Contradiction:

Improveautomation of threat identificationVSAvoidsystem structure for IP filtering

Core Design Contradiction:

Extent of automationVSDevice complexity

Solution Approach 1:

The system introduces intermediary components including web crawlers that scan for suspicious URLs, IP resolution services that translate URLs to IP addresses, and block list databases that store filtered IPs. These intermediary elements work together to automate the threat identification process while managing system complexity through modular design.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A method and apparatus for providing IP address filtering. The method identifies one or more suspicious Uniform Resource Locators (URLs) and resolves the one or more suspicious URLs to one or more suspicious IP addresses. A suspicious IP address list is created containing the one or more suspicious IP addresses. The suspicious IP address list may be used to facilitate a security response to filter one or more of the IP addresses in the suspicious IP address list.
