PR Compliance Guide 🔍

Below is a summary of compliance checks for this PR:

Security Compliance
⚪	Metrics exposure Description: Exposing 'prometheus' and 'metrics' Actuator endpoints over the web without confirming network restrictions or authentication can leak sensitive application metrics (e.g., JVM, HTTP paths), which can aid attackers in reconnaissance. application.yml [20-24] Referred Code management: endpoints: web: exposure: include: health,info,prometheus,metrics
	Unrestricted scrape endpoint Description: Enabling Prometheus scraping on the pod at path '/actuator/prometheus' and port '8080' via annotations may publicly expose metrics if the service is externally accessible or lacks NetworkPolicy/Ingress restrictions. deployment.yml [16-18] Referred Code prometheus.io/scrape: "true" prometheus.io/port: "8080" prometheus.io/path: "/actuator/prometheus"

Codebase Duplication Compliance
⚪	Codebase context is not defined Follow the guide to enable codebase context checks.
Custom Compliance
🟢	Generic: Meaningful Naming and Self-Documenting Code Objective: Ensure all identifiers clearly express their purpose and intent, making code self-documenting Status: Passed Learn more about managing compliance generic rules or creating your own custom rules
	Generic: Secure Error Handling Objective: To prevent the leakage of sensitive system information through error messages while providing sufficient detail for internal debugging. Status: Passed Learn more about managing compliance generic rules or creating your own custom rules
	Generic: Secure Logging Practices Objective: To ensure logs are useful for debugging and auditing without exposing sensitive information like PII, PHI, or cardholder data. Status: Passed Learn more about managing compliance generic rules or creating your own custom rules
⚪	Generic: Comprehensive Audit Trails Objective: To create a detailed and reliable record of critical system actions for security analysis and compliance. Status: Audit coverage unclear: The added configuration exposes Prometheus metrics but does not demonstrate logging of critical actions with required context, which may be handled elsewhere. Referred Code management: endpoints: web: exposure: include: health,info,prometheus,metrics server: port: 10004 Learn more about managing compliance generic rules or creating your own custom rules
	Generic: Robust Error Handling and Edge Case Management Objective: Ensure comprehensive error handling that provides meaningful context and graceful degradation Status: Error handling not shown: The changes add dependencies and configuration only, with no new code paths to assess error handling or edge case management. Referred Code <!-- metrics --> <dependency> <groupId>io.micrometer</groupId> <artifactId>micrometer-registry-prometheus</artifactId> </dependency> Learn more about managing compliance generic rules or creating your own custom rules
	Generic: Security-First Input Validation and Data Handling Objective: Ensure all data inputs are validated, sanitized, and handled securely to prevent vulnerabilities Status: Metrics exposure risk: Exposing '/actuator/prometheus' on port 8080 is added but there is no evidence of network restrictions or authentication, which may be acceptable in-cluster yet requires environment review. Referred Code prometheus.io/scrape: "true" prometheus.io/port: "8080" prometheus.io/path: "/actuator/prometheus" Learn more about managing compliance generic rules or creating your own custom rules

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Impact
Possible issue	Fix Prometheus port mismatch Update the prometheus.io/port annotation in k8s/deployment.yml from "8080" to "10004" to match the application's configured server port. k8s/deployment.yml [17] -prometheus.io/port: "8080" +prometheus.io/port: "10004" Apply / Chat Suggestion importance[1-10]: 9 __ Why: The suggestion correctly identifies a port mismatch between the Prometheus scrape configuration (8080) and the application's server port (10004), which is a functional bug that would prevent metrics collection.	High
Security	Remove redundant and insecure endpoint In application.yml, remove the redundant metrics endpoint from the list of exposed management endpoints to improve security. solo-leveling-notification-service/src/main/resources/application.yml [24] -include: health,info,prometheus,metrics +include: health,info,prometheus Apply / Chat Suggestion importance[1-10]: 6 __ Why: The suggestion correctly points out that the metrics endpoint is redundant when the prometheus endpoint is used, and removing it is a good security practice to reduce the attack surface.
