Distributed Peer Attack Alerting for Network Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional security event and alerting systems face delays in detecting and responding to attacks due to centralized data analysis and limited monitoring of localized network attacks, leading to potential widespread damage from self-propagating malicious code outbreaks.
Innovation Solution
A distributed peer attack alerting method where a community of nodes identifies attacks and transmits alerts, automatically configuring protection measures through a petition model and voting process to rapidly contain threats within the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If centralized security event analysis is used, then manual or automatic response can occur, but the round trip time for alerting is long
Solution Approach 1:
The system segments the centralized security analysis function into distributed peer nodes. Each peer independently monitors its local network segment and can immediately alert others without waiting for centralized processing, eliminating the long round trip time while maintaining coordinated security response capability.
Solution Approach 2:
Peers perform self-monitoring and self-alerting within their local network segments. When a peer detects suspicious activity, it automatically generates and transmits alerts to other peers without requiring centralized intervention, thereby reducing response time while maintaining reliable security coordination.
2Difficulty of detecting and measuring
If monitoring is performed only at network gateway egress and ingress points, then security events can be detected at boundaries, but highly localized network attacks within subnets are missed
Solution Approach 1:
The system divides the network into multiple peer segments, with each peer monitoring its local subnet independently. This segmentation enables detection of localized attacks within each peer's network segment that would otherwise be invisible to centralized gateway monitors, while maintaining the ability to detect attacks at network boundaries.
Solution Approach 2:
Each peer is equipped with local monitoring capabilities tailored to its specific network segment. This local quality approach allows each peer to detect attacks occurring within its own subnet using appropriate local monitoring techniques, while the distributed architecture maintains overall network security awareness.
3Reliability
If centralized alerting model is used, then coordinated response can occur, but the system cannot rapidly contain localized threats
Solution Approach 1:
By segmenting the security response function across distributed peers, each peer can independently and rapidly contain threats within its local segment without waiting for centralized authorization. The segmentation enables both speed of local response and coordination through peer-to-peer communication.
Solution Approach 2:
The system implements rapid feedback loops where peers immediately alert each other of detected threats and can automatically configure protective measures. This feedback mechanism enables rapid containment of localized threats while maintaining coordinated network-wide security response through continuous peer communication.

AI summary
A system and method for distributed peer attack alerting is disclosed. The method includes accessing a peer community wherein the peer community comprises a plurality of nodes comprising a network and wherein at least one of the plurality of nodes comprises an attack identifier. The method further includes identifying an attack at one of the plurality of nodes. In addition, the method includes transmitting an alert to the plurality of nodes, the alert comprising information associated with the attack and automatically configuring at least one attack identifier associated with one of the plurality of nodes in response to the alert.
