Kernel Mitigation Policies for Automated Fleet Attack Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Managing security vulnerabilities in a fleet of computer equipment is excessively complex due to the accumulation of numerous CVEs, requiring manual intervention and inefficient orchestration of mitigation policies across multiple systems.
Innovation Solution
A method and module for detecting attempted cyber attacks by executing mitigation policies in the kernel namespace, sending attack data to a security management server, and automatically installing mitigation policies across a fleet of computers, thereby simplifying the management of security vulnerabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mitigation policies are manually managed across a fleet of computers, then security coverage can be comprehensive, but the complexity of management increases excessively
Solution Approach 1:
The system enables self-service by allowing computers in the fleet to automatically detect, report, and apply mitigation policies without manual intervention. The security management server automatically distributes policies to affected systems, eliminating the need for manual configuration while maintaining comprehensive security coverage across all computers.
Solution Approach 2:
The security management server performs multiple functions including centralized policy management, automatic vulnerability detection, mitigation policy distribution, and attack coordination. This multi-functional approach consolidates what would otherwise require separate manual processes into a single automated system, reducing management complexity while maintaining comprehensive security.
2Measurement precision
If comprehensive vulnerability monitoring is implemented across all computers, then security detection capability is improved, but the time and resources required for manual intervention increase
Solution Approach 1:
The system implements continuous feedback loops where computers automatically monitor for attacks, report detected attempts to the security management server, and receive updated mitigation policies in real-time. This automated feedback mechanism maintains high detection precision while eliminating manual response delays, as the system continuously adapts to new threats without human intervention.
Solution Approach 2:
The system performs preliminary actions by pre-configuring mitigation policies on computers before attacks occur and automatically deploying them when vulnerabilities are detected. This proactive approach ensures that detection capability is maintained at high precision while response time is minimized, as mitigation measures are already in place or rapidly deployed without manual intervention.
3Manufacturing precision
If manual orchestration of mitigation policies is used, then policy customization can be precise, but the productivity of security management decreases
Solution Approach 1:
The security management system automatically customizes and distributes mitigation policies based on detected vulnerabilities and attack patterns, eliminating manual policy creation while maintaining precise customization. The system adapts policies to specific computer configurations and threat types automatically, preserving customization precision while dramatically improving management productivity through automation.
Data Source
AI summary
A method for detecting an attempted cyber attack is described, the method being implemented by a computer, the attack exploiting a vulnerability in a function to be protected running in a process of a user space of said computer, where launching of the execution of the function to be protected results in the execution, before the attack, of a function of the kernel. The method includes executing a mitigation policy in the kernel, the mitigation policy being associated with the function of the kernel and being loaded into a namespace of the kernel associated with the process and dedicated to security, and sending, to a security management server, a message comprising a datum representative of the process.
