Project Design Document: node-oracledb

This document outlines the design and security considerations for the node-oracledb project, a Node.js driver for Oracle Database.

BUSINESS POSTURE

Priorities and Goals:

  • Provide a high-performance, reliable, and secure interface for Node.js applications to interact with Oracle Database.
  • Support a wide range of Oracle Database features and versions.
  • Maintain compatibility with Node.js LTS releases and, where feasible, current releases.
  • Offer an easy-to-use API for developers.
  • Ensure the driver is well-documented and supported.
  • Enable seamless integration with existing Node.js ecosystems and tools.

Business Risks:

  • Data breaches: Unauthorized access to sensitive data stored in Oracle databases due to vulnerabilities in the driver or its dependencies.
  • Data corruption: Accidental or malicious modification of data due to bugs or exploits in the driver.
  • Denial of service: Attacks that prevent legitimate users from accessing the database through the driver.
  • Reputational damage: Security incidents or performance issues could damage the reputation of the project and Oracle.
  • Compliance violations: Failure to meet regulatory requirements related to data security and privacy.
  • Supply chain attacks: Compromise of the driver through malicious third-party dependencies or build processes.

SECURITY POSTURE

Existing Security Controls:

  • security control: Secure coding practices: The project follows secure coding guidelines to minimize vulnerabilities. (Described in CONTRIBUTING.md and source code comments).
  • security control: Dependency management: The project carefully manages its dependencies to reduce the risk of supply chain attacks. (Described in package.json and related files).
  • security control: Regular security audits: The project undergoes periodic security reviews and penetration testing. (Not explicitly documented in the repository, but assumed based on Oracle's security practices).
  • security control: Authentication: The driver supports various Oracle Database authentication mechanisms, including username/password, Oracle Wallet, and external authentication. (Described in documentation and examples).
  • security control: Encryption: The driver supports network encryption (TLS) to protect data in transit. (Described in documentation and examples).
  • security control: Input validation: The driver performs input validation to prevent SQL injection and other injection attacks. (Implemented in the C++ binding layer).
  • security control: Continuous Integration (CI): Automated builds and tests are run on every commit to detect regressions and potential issues. (Implemented using GitHub Actions).

Accepted Risks:

  • accepted risk: The driver relies on the security of the underlying Oracle Client libraries and the Oracle Database itself.
  • accepted risk: Users are responsible for securely managing their database credentials and configuring their database instances appropriately.
  • accepted risk: While efforts are made to support older Node.js and Oracle Database versions, security vulnerabilities may exist in those older versions that are beyond the control of the driver.

Recommended Security Controls:

  • Implement Static Application Security Testing (SAST) in the CI pipeline to automatically scan for potential vulnerabilities in the code.
  • Implement Dynamic Application Security Testing (DAST) to test the running driver for vulnerabilities.
  • Implement Software Composition Analysis (SCA) to identify and manage vulnerabilities in third-party dependencies.
  • Provide detailed security documentation, including best practices for secure configuration and usage.
  • Establish a clear vulnerability disclosure and response process.

Security Requirements:

  • Authentication:
    • Support multiple authentication mechanisms, including username/password, Oracle Wallet, and external authentication.
    • Securely handle and store credentials.
    • Protect against brute-force attacks.
  • Authorization:
    • Enforce database-level access controls.
    • Prevent unauthorized access to data and database operations.
  • Input Validation:
    • Validate all user-supplied input to prevent SQL injection and other injection attacks.
    • Use parameterized queries to avoid SQL injection vulnerabilities.
  • Cryptography:
    • Use strong encryption algorithms and protocols (e.g., TLS) to protect data in transit.
    • Support encryption of data at rest if required by the application.
    • Securely manage cryptographic keys.

Build Process Security Controls:

  • security control: Version Control: All code changes are tracked in a Git repository (GitHub).
  • security control: Automated Builds: GitHub Actions automates the build process on every commit.
  • security control: Dependency Management: Dependencies are managed using npm and declared in package.json.
  • security control: Testing: Automated tests are run as part of the build process to ensure code quality and prevent regressions. This includes unit tests and integration tests.
  • security control: (Recommended) Static Analysis: Incorporate SAST tools (e.g., SonarQube, ESLint with security plugins) into the GitHub Actions workflow to scan for potential vulnerabilities.
  • security control: (Recommended) Software Composition Analysis: Use SCA tools (e.g., npm audit, Snyk) to identify and manage vulnerabilities in third-party dependencies.

RISK ASSESSMENT

Critical Business Processes:

  • Accessing and managing data stored in Oracle Databases.
  • Providing a reliable and performant connection between Node.js applications and Oracle Databases.

Data Sensitivity:

  • The sensitivity of the data depends on the specific application and the data stored in the Oracle Database. It can range from non-sensitive to highly sensitive (e.g., PII, financial data, healthcare data). The node-oracledb driver itself does not inherently handle sensitive data differently; it relies on the application and database configuration for data protection.

QUESTIONS & ASSUMPTIONS

Questions:

  • What specific security certifications or compliance requirements (e.g., PCI DSS, HIPAA) must the driver adhere to?
  • Are there any specific Oracle Database security features (e.g., Oracle Advanced Security, Database Vault) that the driver needs to support explicitly?
  • What is the expected threat model for applications using this driver?
  • What level of security auditing and penetration testing is performed on the driver and its dependencies?
  • Is there a formal vulnerability disclosure program for the project?

Assumptions:

  • BUSINESS POSTURE: It is assumed that Oracle prioritizes the security of its products and services, including node-oracledb.
  • SECURITY POSTURE: It is assumed that the underlying Oracle Client libraries and Oracle Database are properly secured and configured.
  • DESIGN: It is assumed that the Node.js application using the driver will also implement appropriate security controls.
  • DEPLOYMENT: It is assumed that the deployment environment (whether on-premises or in the cloud) is secured according to best practices.
  • BUILD: It is assumed that the build process is secure and that dependencies are regularly reviewed for vulnerabilities.
