Network Security System with Risk-Based Authentication Restrictions

The system performs preliminary actions by detecting and tracking failed authentication attempts before unauthorized access can be established. The security system monitors authentication attempts in real-time, calculates risk scores based on the number of failures, and prepares restriction measures in advance. When a device successfully authenticates after multiple failures, the system has already predetermined the application of network restrictions, preventing potential damage before it occurs.

The system implements feedback mechanisms by continuously monitoring authentication attempts and adjusting risk scores dynamically. The risk score is updated based on the number of failed attempts, and this feedback loop enables the system to adapt its security response. The notification system provides feedback to administrators about high-risk devices, enabling informed security decisions while maintaining automated response capabilities.

The system applies local quality by implementing differentiated security responses based on the specific risk profile of each device. Instead of uniformly restricting all devices with failed attempts, the system calculates individual risk scores and applies restrictions only to devices exceeding the threshold. This localized approach ensures that legitimate users with occasional authentication errors (such as typos) are not unnecessarily restricted, while truly suspicious devices are targeted for restriction.

The system utilizes parameter changes by dynamically adjusting the risk score parameter based on the number of failed authentication attempts. The risk score serves as a variable parameter that changes with each failed attempt, allowing the system to adapt its security posture. The threshold parameter provides a configurable boundary that balances security and productivity, enabling administrators to adjust the sensitivity of the restriction mechanism based on their specific needs.

The system implements self-service by automatically performing detection, risk assessment, and restriction application without requiring continuous administrator intervention. The security system autonomously monitors authentication attempts, calculates risk scores, identifies high-risk devices, and applies network restrictions automatically. This self-service capability reduces the operational complexity for administrators while maintaining high detection precision through continuous automated monitoring.

The system applies segmentation by dividing the security monitoring function into discrete, manageable components: authentication attempt detection, risk score calculation, threshold comparison, notification generation, and restriction application. This modular segmentation reduces system complexity by making each component independent and easily implementable, while the collective operation of these segments achieves comprehensive monitoring with high detection precision.
