Certificate Resiliency Validation via Chaos Engineering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current certificate management testing methods are prone to human error and do not provide a seamless way to test certificate-related code for failure scenarios, leading to potential outages and breaches, as they require manual code writing and do not adequately simulate certificate unavailability or degradation scenarios.
Innovation Solution
A method and system for certificate management resiliency testing that aggregates faults into a library, allowing users to design experiments that simulate certificate-related faults, such as disabled certificates, secrets vault unavailability, and attribute alterations, enabling comprehensive and accurate analysis without manual code writing, ensuring adherence to best practices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual code writing is used for certificate management testing, then testing can be performed, but human error increases and testing completeness decreases
Solution Approach 1:
The system performs self-testing by automatically generating and executing test cases for certificate management code. The resiliency testing system autonomously creates experiments, injects faults, and monitors outcomes without requiring manual code writing, thereby eliminating human error while maintaining testing accuracy.
Solution Approach 2:
The system pre-defines a comprehensive library of certificate-related faults and experiment templates before actual testing begins. This preliminary preparation includes various certificate scenarios (expired, disabled, attribute alterations) that are ready to be automatically applied, eliminating the need for manual code creation during testing execution.
2Reliability
If comprehensive certificate failure scenarios are simulated, then system resiliency is validated, but testing complexity increases
Solution Approach 1:
The resiliency testing system serves multiple functions within a single unified platform: it manages certificate lifecycles, generates test cases, injects various fault types, executes experiments, and monitors outcomes. This multi-functionality allows comprehensive resiliency validation without proportionally increasing system complexity, as all testing operations are handled by one integrated system.
Solution Approach 2:
The system validates resiliency by systematically changing certificate parameters (expiry dates, disabled status, attribute values) through predefined fault injections. Rather than creating complex testing logic for each scenario, the system varies certificate parameters to automatically generate diverse test cases, simplifying the overall testing architecture while maintaining comprehensive validation.
3Productivity
If automated resiliency testing is implemented, then human error is reduced, but initial system setup complexity increases
Solution Approach 1:
The system uses templates and copies of predefined fault patterns and experiment structures to automate testing. Rather than building complex testing logic from scratch, the system replicates standardized test case templates for different certificate scenarios, reducing initial setup complexity while maintaining high testing efficiency through automation.
Solution Approach 2:
The testing infrastructure is segmented into modular components: a fault library containing discrete fault types, an experiment engine for executing tests, and a monitoring system for collecting results. This segmentation allows the complex automated testing system to be built and maintained through independent, manageable modules, reducing overall setup complexity while preserving automation benefits.

AI summary
Generally discussed herein are devices, systems, and methods for certificate management resiliency validation. A method can include receiving, at a resiliency tester of a cloud network, experiment data defining a certificate management resilience experiment to be performed on a resource of the cloud network, accessing, by the resiliency tester and a fault library and based on the experiment data, one or more faults that implement the certificate management resilience experiment, altering, by the resiliency tester and based on the experiment data, an attribute of a certificate, a version of the certificate, accessibility to a secrets vault that houses the certificate, or a combination thereof resulting in a modified certificate or modified certificate availability, and altering a certificate management tool based on telemetry data regarding access of the modified certificate.
