Centralized CSP Management System for Automated Policy Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional Content Security Policy (CSP) management involves hard-coding CSP headers into each web application, which is difficult to maintain, especially for enterprises with numerous web applications and varying dependencies.
Innovation Solution
A CSP management system that allows administrators to generate, edit, and manage CSP definitions centrally. The system retrieves CSP definitions for web applications, generates CSP headers, and updates definitions based on CSP violations by comparing violating sources with a list of trusted sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If CSP headers are hard-coded into each web application, then security policy enforcement is achieved, but maintenance difficulty increases significantly for enterprises with numerous web applications
Solution Approach 1:
The patent extracts the CSP definition management from individual web applications and places it in a separate centralized CSP management system. The CSP definitions are stored externally in a repository rather than being hard-coded, allowing centralized management while maintaining security enforcement at each application level through the CSP header generation process
Solution Approach 2:
The patent introduces a CSP management system as an intermediary between administrators and web applications. This intermediary handles CSP definition creation, storage, retrieval, and updates, mediating the security policy enforcement across multiple applications without requiring direct modification of each application's code
2Ease of repair
If CSP definitions are managed centrally, then maintenance ease is improved, but system complexity increases due to additional components
Solution Approach 1:
The CSP management system performs multiple functions: storing CSP definitions, generating CSP headers, comparing violating sources with trusted sources, and automatically updating definitions. This multi-functional approach consolidates what could be separate complex components into a single unified system, reducing overall system complexity while maintaining centralized management benefits
3Measurement precision
If CSP headers are manually updated for each violation, then security accuracy is maintained, but time consumption increases significantly
Solution Approach 1:
The CSP management system automatically updates CSP definitions by comparing violating sources with trusted sources without requiring manual administrator intervention. The system serves itself by detecting violations, performing comparisons, and updating definitions autonomously, maintaining security accuracy while eliminating manual time consumption
Solution Approach 2:
The system implements a feedback loop where CSP violations are reported back to the management system, which then automatically processes the violation information by comparing it with trusted sources and updating the CSP definitions accordingly. This closed-loop feedback mechanism ensures security accuracy is maintained while automating the response process
4Productivity
If trusted sources are automatically added to CSP definitions, then productivity is improved by reducing manual work, but security risk may increase if untrusted sources are mistakenly added
Solution Approach 1:
The system performs preliminary verification by maintaining a pre-established list of trusted sources before automatically adding any source to CSP definitions. By pre-identifying and storing trusted sources, the system ensures that only verified trustworthy sources are added, eliminating security risks while maintaining automated productivity benefits

AI summary
Systems and methods provide for self-healing content security policies (CSPs). In accordance with some aspects, CSP violation information is received identifying a CSP violation for a CSP header and a violating source for the CSP violation. The violating source for the CSP violation is compared against a list of trusted sources. Based on the comparison, a first trusted source in the list of trusted sources is identified as matching the violating source for the CSP violation. Responsive to identifying the first trusted source as matching the violating source, a CSP definition associated with the CSP header is caused to be updated to include a source value based on the violating source or the first trusted source to provide an updated CSP definition.
