Preemptive Threat Detection via Bad Actor Profiling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network security systems are unable to detect network attacks in real-time, allowing malicious actors to gain unauthorized access, perform data exfiltration, or upload malware, resulting in delayed responses and compromised network performance.
Innovation Solution
The system identifies potential bad actors in public networks by generating bad actor profiles based on threat indicators, which are then used to monitor and block malicious communications with private network devices, thereby preempting attacks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing network security systems are used, then network devices can communicate freely in public networks, but attacks cannot be detected until after they occur
Solution Approach 1:
The system performs preliminary actions by proactively identifying and profiling potential bad actors in public networks before attacks occur. Threat detection devices continuously monitor public networks, generate bad actor profiles based on identified threats, and prepare blocking rules in advance. When a potential attack is detected, the system can immediately block communications without delay, as the threat intelligence and blocking mechanisms are already in place.
2Reliability
If preemptive threat detection is implemented, then attacks can be blocked before occurrence, but network device complexity increases
Solution Approach 1:
The threat detection system is segmented into distinct functional components: threat detection devices that monitor public networks, profile generation modules that create bad actor profiles, and blocking mechanisms that prevent communications. This segmentation allows each component to perform its specific function efficiently while maintaining overall system manageability. The modular architecture enables independent deployment and updating of different security functions.
Solution Approach 2:
Bad actor profiles serve as intermediaries between threat intelligence and blocking actions. Instead of directly implementing complex blocking logic, the system uses pre-generated profiles containing threat indicators, device identifiers, and behavioral patterns as intermediary data structures. These profiles simplify the blocking decision process by providing ready-to-use matching criteria that can be efficiently compared against network communications.
3Measurement precision
If comprehensive bad actor profiling is performed, then more complete threat information is obtained, but more network resources are consumed
Solution Approach 1:
The system applies partial action by focusing profiling efforts on specific high-risk scenarios and target networks rather than uniformly monitoring all communications. The coarse-to-fine search strategy performs initial broad scanning to identify potential threats, then concentrates resources on generating detailed profiles only for suspicious entities. This selective approach achieves comprehensive threat coverage for critical areas while conserving network resources by avoiding exhaustive profiling of all traffic.
Data Source
AI summary
A device configured to receive a data sample about a configuration for one or more network devices in a public network. The device is further configured to compare one or more threat indicators to the data sample where each threat indicator is associated with a configuration setting. The device is further configured to identify a first network device in the public network that comprises a configuration that matches a threat indicator and to generate a bad actor profile for the first network device. The device is further configured to receive data traffic for a second network device in a private network and to block data communications between the second network device in the private network and the first network device in the public network in response to determining that the first network device is associated with the bad actor profile.
