Mitigation Strategies Analysis for ankane/pghero

Mitigation Strategy: Securely Store Database Credentials for pghero

  • Mitigation Strategy: Securely Store Database Credentials for pghero using Environment Variables and Secrets Management.

  • Description:

    1. Identify all locations where database credentials for pghero are currently stored (e.g., pghero configuration files, application code).
    2. Remove hardcoded credentials from all files and code related to pghero configuration.
    3. Set database connection details as environment variables on the server or environment where pghero is deployed. Use environment variables specifically read by pghero, such as PGHERO_DATABASE_URL, PGHERO_USERNAME, PGHERO_PASSWORD, PGHERO_HOST, PGHERO_PORT.
    4. Optionally, for enhanced security, use a secrets management system:
      • Configure a secrets management system (e.g., HashiCorp Vault, AWS Secrets Manager) to store the database credentials used by pghero.
      • Modify the pghero application configuration to retrieve credentials from the secrets management system instead of directly from environment variables. This might require code changes within the application to integrate with the chosen secrets manager.
      • Ensure proper authentication and authorization for the pghero application to access the secrets management system.

  • List of Threats Mitigated:

    • Hardcoded Credentials Exposure (High Severity): If credentials for pghero are hardcoded and the codebase or configuration files are compromised, attackers can gain direct access to the PostgreSQL database via the pghero user.
    • Accidental Credential Leakage (Medium Severity): Hardcoded credentials for pghero can be accidentally exposed through logs, commit history, or configuration backups.

  • Impact:

    • Hardcoded Credentials Exposure: High risk reduction. Eliminates the primary vulnerability of directly exposed credentials used by pghero.
    • Accidental Credential Leakage: Medium risk reduction. Environment variables are less likely to be accidentally committed than hardcoded values. Secrets management further reduces this risk.

  • Currently Implemented:

    • Environment Variables: Partially implemented. Database connection details for pghero are currently read from environment variables in production.
    • Secrets Management: Not implemented.

  • Missing Implementation:

    • Secrets Management: Missing in all environments. Consider implementing secrets management for production and staging for enhanced security of pghero's database credentials.

Mitigation Strategy: Principle of Least Privilege for pghero Database User

  • Mitigation Strategy: Implement Principle of Least Privilege for the dedicated pghero Database User.

  • Description:

    1. Connect to the PostgreSQL database as a superuser or a user with sufficient privileges.
    2. Create a dedicated PostgreSQL user specifically for pghero. Choose a descriptive username, e.g., pghero_monitor.
    3. Revoke all default privileges from this newly created pghero user.
    4. Grant CONNECT privilege to the databases that pghero needs to monitor.
    5. Grant SELECT privileges only on the specific PostgreSQL system tables and views required by pghero. Refer to pghero documentation or source code to identify the necessary tables and views (e.g., pg_stat_statements, pg_locks, etc.).
    6. Do not grant any INSERT, UPDATE, DELETE, or DDL privileges to the pghero_monitor user.

  • List of Threats Mitigated:

    • SQL Injection via pghero (Low Severity): Limiting privileges minimizes potential damage if a vulnerability in pghero were to be exploited for SQL injection, even though pghero is designed for read-only operations.
    • Accidental or Malicious Data Modification (Medium Severity): Restricting privileges prevents accidental or malicious modification or deletion of database data through the pghero user account if it were compromised.
    • Lateral Movement after pghero Compromise (Medium Severity): Limiting privileges restricts an attacker's ability to escalate privileges or move laterally within the database system if pghero or its credentials are compromised.

  • Impact:

    • SQL Injection via pghero: Low risk reduction. Defense-in-depth measure.
    • Accidental or Malicious Data Modification: Medium risk reduction. Significantly reduces potential data integrity issues.
    • Lateral Movement after pghero Compromise: Medium risk reduction. Limits attacker capabilities within the database.

  • Currently Implemented:

    • Partially implemented. A dedicated pghero user exists, but specific privileges granted have not been strictly limited to the minimum required for pghero.

  • Missing Implementation:

    • Privilege Review and Restriction: Missing in all environments. Need to audit and restrict the privileges of the pghero user to the absolute minimum required for its monitoring functions.

Mitigation Strategy: Implement Authentication for pghero Dashboard

  • Mitigation Strategy: Implement Robust Authentication for pghero Dashboard Access.

  • Description:

    1. Choose an authentication mechanism suitable for a Rails application like pghero (e.g., devise, clearance).
    2. Integrate the chosen authentication gem into the pghero application.
    3. Implement user registration and login functionality within pghero.
    4. Protect the pghero dashboard routes by requiring authentication. Use authentication filters to ensure only authenticated users can access the pghero dashboard.
    5. Enforce strong password policies for pghero dashboard users.
    6. Consider implementing Multi-Factor Authentication (MFA) for enhanced security of pghero dashboard access.

  • List of Threats Mitigated:

    • Unauthorized Access to Performance Metrics (High Severity): Without authentication on the pghero dashboard, anyone with the URL can view potentially sensitive database performance metrics.
    • Information Disclosure (High Severity): Performance metrics exposed by pghero can indirectly reveal sensitive information.

  • Impact:

    • Unauthorized Access to Performance Metrics: High risk reduction. Authentication is the primary control to prevent unauthorized pghero dashboard access.
    • Information Disclosure: High risk reduction. Limits information disclosure by controlling access to the pghero dashboard.

  • Currently Implemented:

    • Not implemented. The pghero dashboard is currently accessible without any authentication.

  • Missing Implementation:

    • Authentication Implementation: Missing in all environments. Requires development effort to integrate authentication into the pghero application.

      • Investigate if pghero allows for disabling or customizing metric collection. Check pghero configuration options or code.
      • If customization within pghero is limited, consider the risk-benefit trade-off.
      • If risks are too high, consider alternative monitoring solutions if pghero's metric exposure is a critical issue.
    4. Document the rationale for metrics exposed or limited by pghero.

  • List of Threats Mitigated:

    • Information Disclosure through Metrics (Medium Severity): Pghero exposing overly detailed metrics could reveal sensitive information.
    • Competitive Intelligence Leakage (Low to Medium Severity): Metrics displayed by pghero could provide competitors with insights.

  • Impact:

    • Information Disclosure through Metrics: Medium risk reduction. Limiting pghero's metric exposure reduces potential leakage.
    • Competitive Intelligence Leakage: Low to Medium risk reduction. Minimizes risk of sharing competitive intelligence via pghero's data.

  • Currently Implemented:

    • Not implemented. No specific review or limitation of pghero's exposed metrics has been performed.

  • Missing Implementation:

    • Metric Review and Sensitivity Assessment: Missing in all environments. A review of pghero metrics is needed to address potential information disclosure risks.
