Security Policy Tracking with Incident Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network security systems face challenges in effectively implementing and tracking security policy coverage, objectively assessing policy effectiveness, and identifying potential security threats, making it difficult to monitor and respond to security policy violations in a timely and efficient manner.
Innovation Solution
The method involves creating rules based on security policies, parsing log data to determine variable values, evaluating rules, generating security events, and recording these events to identify violations, anomalies, and generating alerts, with the ability to associate geographic regions and analyze statistical data for network security assessment and reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If security policies are created to address network risks, then security coverage is improved, but implementation and enforcement difficulty increases
Solution Approach 1:
The system automatically parses logs, evaluates rules, generates security events, and sends alerts without requiring manual intervention. The monitoring system serves itself by continuously analyzing network data and enforcing security policies through automated workflows, reducing the operational burden on security personnel while maintaining comprehensive security coverage
Solution Approach 2:
The system implements continuous feedback loops by monitoring security events, generating alerts when policies are violated, and providing visibility into security posture through dashboards and reports. This feedback mechanism enables real-time adjustment and enforcement of security policies, making implementation more effective and manageable
2Difficulty of detecting and measuring
If continuous monitoring of security policy violations is implemented, then security detection capability is improved, but system complexity increases
Solution Approach 1:
The monitoring system is divided into distinct modular components: log parsing module, rule evaluation module, security event generation module, and alert notification module. Each component performs a specific function independently, making the overall complex system manageable through clear separation of concerns and enabling targeted optimization of individual modules
Solution Approach 2:
The system uses universal log parsing capabilities that can handle multiple log formats and sources, and rule evaluation mechanisms that work across different security policies. This multi-functionality reduces complexity by avoiding the need for separate specialized systems for each security monitoring task

AI summary
The present invention relates to methods, processes, and systems for monitoring security policy violations in a computer network. Details of such monitoring include creating a rule according to a security policy, determining if the rule is violated by a value of a variable, and recording security events and comparing the number of events to a threshold.
