Automated SELinux Policy Deployment via Reference System Copying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The deployment of SELinux security policies for new operating system distributions is labor-intensive and time-consuming, especially when multiple systems with slight differences need to be deployed, increasing the risk of human error.
Innovation Solution
A method and system for automatically labeling objects and generating security policies in operating systems by comparing target attributes with reference attributes, using default labels, reference labels, or candidate labels, and generating system audit messages to form security policies through a policy generator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual analysis of source code behavior is performed to adjust system settings for SELinux policy deployment, then security policy accuracy is improved, but labor cost and time cost increase multiplicatively when deploying multiple operating system distributions
Solution Approach 1:
The patent copies security policies from a reference operating system to a target operating system. The policy copying module retrieves security policies from the reference OS and applies them to the target OS, eliminating the need for manual analysis for each new deployment. This copying approach maintains policy accuracy while dramatically improving deployment efficiency across multiple distributions.
Solution Approach 2:
The patent performs preliminary actions by pre-configuring security policies in a reference operating system. Once the reference OS has its security policies established through manual analysis, these pre-configured policies can be automatically copied to multiple target systems. This preliminary setup eliminates repetitive manual work for subsequent deployments.
2Adaptability or versatility
If manual adjustment of system settings is performed for each new operating system distribution, then adaptability to specific system requirements is improved, but the possibility of human operation errors increases
Solution Approach 1:
By copying proven security policies from a reference system rather than manually configuring each target system, the patent eliminates human operation errors associated with repetitive manual configuration. The copying process ensures consistency and accuracy across all deployments while maintaining adaptability through selective policy application.
Solution Approach 2:
The patent enables self-service through automated policy deployment mechanisms. The system automatically retrieves, adapts, and applies security policies without requiring manual intervention for each deployment. This self-service approach reduces human error while maintaining system-specific adaptability through automated detection and configuration.
3Reliability
If comprehensive manual analysis is performed for each operating system deployment, then security policy completeness is improved, but time cost increases multiplicatively
Solution Approach 1:
The patent copies comprehensive security policies from a reference operating system that has already undergone thorough analysis. This copying mechanism preserves the completeness of security coverage while reducing deployment time from hours or days to minutes, as the complete policy set is automatically transferred rather than重新analyzed.
Solution Approach 2:
The patent performs comprehensive security analysis as a preliminary action on the reference operating system. Once the complete security policy framework is established in the reference system, this preliminary work serves all subsequent deployments, eliminating the need to repeat the time-consuming analysis process for each new distribution.

AI summary
A method for labeling object of operating system is adapted to a target object of a target operating system, wherein the target object has a target attribute. The method comprises: generating a default label by a labeling tool according to the target attribute; obtaining a reference object of a reference operating system, wherein the reference object has a reference attribute and a reference label; comparing whether the target attribute and the reference attribute are identical and generating a comparison result; and labeling the target object with the default label, the reference label, or one of a plurality of candidate labels according to the comparison result and a type of the target object.
