Aggregation Agent for Network Security Alert Correlation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing complexity and number of agent-based security solutions in networked devices lead to duplicate information crowding network bandwidth, potential vulnerabilities due to multiple open ports, and complex security management, with no assurance of alert authenticity.
Innovation Solution
An aggregation agent is deployed on the host system to authenticate and correlate alert data from multiple agents, compressing and encrypting messages to reduce bandwidth usage and secure communication, while ensuring message authenticity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple agents are deployed to monitor security conditions, then security coverage and detection capability are improved, but network bandwidth is crowded by duplicate information and device complexity increases
Solution Approach 1:
Multiple security agents are merged into a single aggregated security information message that consolidates alerts from antivirus, firewall, intrusion detection, and other security components. This merging reduces the number of separate communications while maintaining comprehensive security coverage, directly resolving the contradiction between improved security detection and reduced system complexity.
Solution Approach 2:
The aggregated security message serves multiple functions simultaneously: it provides comprehensive security monitoring across multiple agents, reduces network bandwidth consumption, simplifies message routing, and enables centralized management. This multi-functionality allows a single message structure to achieve what previously required multiple separate communication channels.
2Speed
If each agent transmits alerts independently, then real-time security monitoring is improved, but network bandwidth is consumed by duplicate information
Solution Approach 1:
Security alerts from multiple agents are combined into a single aggregated message that maintains real-time transmission capabilities. The aggregation process consolidates duplicate information while preserving the speed advantage of immediate alert delivery, resolving the contradiction between fast alert transmission and network bandwidth conservation.
3Adaptability or versatility
If multiple ports are opened for agent communications, then agent connectivity and reporting capability are improved, but system vulnerability increases
Solution Approach 1:
Multiple communication ports used by individual agents are merged into a single aggregated security message channel. This consolidation maintains the ability of all security agents to report to the management server while reducing the number of open ports from many individual agent ports to a single aggregated communication interface, thereby maintaining connectivity while reducing vulnerability.
4Ease of operation
If security alerts are transmitted without authentication, then transmission simplicity is improved, but alert authenticity cannot be ensured
Solution Approach 1:
An authentication mechanism is introduced as an intermediary component within the aggregated security message framework. This intermediary validates the authenticity of alerts during the aggregation process without complicating the overall transmission simplicity, resolving the contradiction between easy transmission and reliable authentication.
Data Source
AI summary
An aggregation agent may combine and correlate information generated by multiple on-host agents and/or information generated in response to multiple security events. The aggregation agent may transmit the combined information to a security console. The security console may check the identity of the aggregation agent to determine whether to accept the information. The security console may map information to one or more consoles.
