Network Vulnerability Impact Assessment Through Device Telemetry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The growing number of software vulnerabilities and dynamic network device configurations make risk assessment for cybersecurity/network administrators unmanageable, necessitating a system to provide a comprehensive view of vulnerability impact on networks.
Innovation Solution
A system that analyzes unresolved vulnerabilities against current network device configurations using telemetry data streams to generate an impact analysis report, continuously collecting and evaluating device configurations and vulnerability representations to determine affected devices and aggregate impact data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the number of software vulnerabilities is tracked comprehensively, then the completeness of vulnerability assessment is improved, but the manageability of risk assessment deteriorates
Solution Approach 1:
The system segments the vulnerability assessment task by filtering vulnerabilities based on device configuration attributes (OS type, version, architecture) and network device roles. This divides the comprehensive vulnerability list into manageable subsets relevant to specific devices, making the assessment process tractable while maintaining completeness through systematic coverage of all device types and configurations.
Solution Approach 2:
The system applies local quality by tailoring vulnerability assessments to specific device configurations and network roles. Instead of treating all vulnerabilities uniformly, the system customizes the assessment criteria and impact analysis based on the specific characteristics of each device type and configuration, making the assessment both comprehensive and manageable through localized relevance filtering.
2Measurement precision
If device configurations are updated continuously to maintain current state, then the accuracy of vulnerability impact analysis is improved, but the system complexity increases
Solution Approach 1:
The system implements self-service by having network devices automatically report their own configuration states through telemetry data streams. This eliminates the need for manual configuration collection or complex external monitoring systems, maintaining accurate device configuration information while minimizing system complexity through device-initiated data provision.
Solution Approach 2:
The system uses feedback mechanisms where devices continuously send telemetry data about their configuration states, and the vulnerability assessment system updates its device configuration database accordingly. This feedback loop ensures continuous accuracy of vulnerability impact analysis without requiring complex configuration management infrastructure, as the data flow is driven by device reporting rather than system-initiated complex coordination.
Data Source
AI summary
A system as disclosed herein analyzes unresolved vulnerabilities against current configurations of devices of a network to generate an impact analysis report which provides a comprehensive view of the impact of the vulnerabilities on the network. This provides a manageable perspective of risk assessment and remediation for the network. To maintain a current view of device configurations, telemetry data streams are collected from the devices. A listing of outstanding or unresolved cybersecurity vulnerabilities is also maintained. When an analysis trigger is detected, the system extracts values of configuration properties for devices from the telemetry data streams and analyses them against the list of vulnerabilities to determine devices affected by the vulnerabilities. Tracking data are maintained according to the determinations of affected devices across vulnerabilities. This data is aggregated into an impact report that indicates impact of vulnerabilities to the network.
