Mitigation Strategies Analysis for locustio/locust

Mitigation Strategy: Rate Limiting in Locust Scripts

Description:

  1. Identify critical request types: Determine which requests in your Locust scripts are most likely to overload the target application if sent in excessive volume.
  2. Implement rate limiting logic: Within your Locust task sets, introduce mechanisms to control the frequency of these critical requests using time.sleep() or rate limiting libraries.
  3. Configure rate limits: Set appropriate sleep times or rate limit parameters based on the target application's capacity and desired load profile.
  4. Test rate limiting: Verify that the rate limiting logic functions correctly in your Locust scripts.
  5. Document rate limits: Clearly document the implemented rate limiting strategies within the Locust scripts.

Threats Mitigated:

  • Overload and Denial of Service (DoS) against Target Application - Severity: High

Impact:

  • Overload and Denial of Service (DoS) against Target Application - High reduction

Currently Implemented: Not Implemented

Missing Implementation: Rate limiting is not currently implemented in any Locust scripts. This needs to be added to all load tests.

Mitigation Strategy: Realistic User Behavior Modeling

Description:

  1. Analyze production traffic patterns: Study real user traffic patterns to understand typical user journeys, request frequencies, think times, and session durations.
  2. Model user behavior in Locust tasks: Design Locust task sets to accurately reflect these real-world user behaviors, including realistic think times and probabilistic task execution.
  3. Avoid unrealistic load patterns: Refrain from creating Locust scripts that generate artificial or exaggerated load patterns.
  4. Validate load profiles: Compare the load profiles generated by Locust scripts with the analyzed production traffic patterns.
  5. Iterate and refine: Continuously review and refine Locust scripts based on updated production traffic data.

Threats Mitigated:

  • Overload and Denial of Service (DoS) against Target Application (due to unrealistic load) - Severity: Medium

Impact:

  • Overload and Denial of Service (DoS) against Target Application - Medium reduction

Currently Implemented: Partially Implemented

Missing Implementation: Some Locust scripts use basic think times, but a comprehensive analysis of production traffic patterns and detailed modeling of user behavior is missing.

Mitigation Strategy: Secure Coding Practices for Locust Scripts

Description:

  1. Code reviews for Locust scripts: Incorporate code reviews into the development process for Locust scripts.
  2. Input validation and sanitization: If Locust scripts handle external input, implement input validation and sanitization.
  3. Secure API interactions: Ensure that API calls made within Locust scripts are secure (HTTPS, authentication).
  4. Error handling and exception management: Implement robust error handling in Locust scripts.
  5. Regular security training: Provide security awareness training to developers writing Locust scripts.

Threats Mitigated:

  • Security Vulnerabilities in Locust Scripts (e.g., Injection Flaws, Insecure API Calls) - Severity: Medium to High

Impact:

  • Security Vulnerabilities in Locust Scripts - Medium to High reduction

Currently Implemented: Partially Implemented

Missing Implementation: Code reviews are not consistently performed for Locust scripts. Input validation and sanitization are not systematically implemented. Security training for Locust script development is not formally established.

Mitigation Strategy: Secrets Management for Locust Credentials

Description:

  1. Identify sensitive credentials: Determine all credentials used in Locust scripts.
  2. Choose a secrets management solution: Select a secure secrets management solution.
  3. Store secrets securely: Store all identified credentials in the chosen secrets management solution.
  4. Retrieve secrets in Locust scripts: Modify Locust scripts to retrieve credentials dynamically from the secrets management solution.
  5. Rotate secrets regularly: Implement a process for regular rotation of credentials.

Threats Mitigated:

  • Exposure of Sensitive Credentials in Locust Scripts - Severity: High
  • Unauthorized Access due to Hardcoded Credentials - Severity: High

Impact:

  • Exposure of Sensitive Credentials in Locust Scripts - High reduction
  • Unauthorized Access due to Hardcoded Credentials - High reduction

Currently Implemented: Partially Implemented

Missing Implementation: Environment variables are used for some credentials, but not consistently. A dedicated secrets management solution is not yet implemented. Credential rotation is not automated.

Mitigation Strategy: Regular Locust and Dependency Updates

Description:

  1. Track Locust and dependency versions: Maintain a record of the versions of Locust and its dependencies.
  2. Monitor security advisories: Regularly monitor security advisories for Locust and its dependencies.
  3. Establish an update process: Define a process for regularly updating Locust and its dependencies.
  4. Automate dependency updates (where possible): Explore using dependency management tools to automate updates.
  5. Prioritize security updates: Prioritize applying security updates for Locust and its dependencies promptly.

Threats Mitigated:

  • Exploitation of Known Vulnerabilities in Locust or Dependencies - Severity: Medium to High

Impact:

  • Exploitation of Known Vulnerabilities in Locust or Dependencies - High reduction

Currently Implemented: Partially Implemented

Missing Implementation: Dependency versions are tracked, but security advisories are not actively monitored. A formal update process is not in place. Dependency updates are performed manually and not regularly.

Mitigation Strategy: Data Minimization in Locust Scripts

Description:

  1. Identify sensitive data usage: Review Locust scripts to identify instances where sensitive data is handled.
  2. Minimize sensitive data handling: Reduce the amount of sensitive data used in Locust scripts to the minimum necessary.
  3. Anonymize or pseudonymize data: Replace sensitive data with anonymized or pseudonymized data whenever possible.
  4. Avoid logging sensitive data: Configure Locust logging to prevent logging sensitive data in plain text.
  5. Review data usage regularly: Periodically review Locust scripts and test data to ensure continued adherence to data minimization principles.

Threats Mitigated:

  • Exposure of Sensitive Data in Locust Scripts and Logs - Severity: Medium to High
  • Data Breaches due to Exposed Sensitive Data - Severity: Medium to High

Currently Implemented: Not Implemented

Missing Implementation: Data minimization practices are not formally implemented in Locust script development. Sensitive data usage in scripts and test data is not systematically reviewed or minimized.

Mitigation Strategy: Secure Logging Practices for Locust

Description:

  1. Configure logging levels: Set appropriate logging levels for Locust to minimize verbose logging.
  2. Avoid logging sensitive data: Configure Locust logging to explicitly exclude sensitive data from logs. Sanitize data before logging if necessary.
  3. Implement log rotation and retention: Configure log rotation and retention policies for Locust logs.
  4. Secure log storage: Store Locust logs in a secure location with access controls.
  5. Centralized logging (optional): Consider using a centralized logging system for Locust logs.

Missing Implementation: Basic logging is configured, but sensitive data is not explicitly excluded from logs. Log rotation and retention policies are not formally defined.

Mitigation Strategy: Secure Transmission of Locust Metrics

Description:

  1. Identify metrics transmission channels: Determine how Locust metrics and test results are transmitted.
  2. Use secure transmission protocols: Ensure that all channels use secure protocols like HTTPS.
  3. Encrypt sensitive metrics data: If metrics data contains sensitive information, consider encrypting the data before transmission.
  4. Authenticate and authorize access to metrics endpoints: Implement authentication and authorization for metrics endpoints.
  5. Secure storage of metrics data: If metrics data is stored persistently, ensure secure storage practices.
