Study Notes

Secure Coding Practices

  • Input Validation

    • Always validate and sanitize user inputs.
    • Use whitelisting over blacklisting for acceptable input.

  • Error Handling

    • Avoid displaying detailed error messages to users.
    • Log errors securely without revealing sensitive information.

  • Authentication and Access Control

    • Implement strong password policies (length, complexity).
    • Use multi-factor authentication (MFA) for sensitive operations.

  • Data Protection

    • Use encryption for sensitive data both in transit and at rest.
    • Store passwords securely using hashing algorithms (e.g., bcrypt, Argon2).

  • Session Management

    • Use secure, HTTP-only cookies for session identifiers.
    • Implement session expiration and invalidation upon logout.

  • Code Dependencies

    • Regularly update and patch third-party libraries and frameworks.
    • Use tools to scan for vulnerabilities in dependencies.

  • Principle of Least Privilege

    • Grant users and processes only the permissions necessary for their functions.
    • Regularly review and adjust permissions as necessary.

  • Secure Data Storage

    • Avoid hardcoding sensitive information in source code.
    • Utilize secure vaults or secret management tools for sensitive data.

  • Secure Communication

    • Use TLS/SSL for secure data transmission.
    • Validate SSL certificates to prevent man-in-the-middle attacks.

  • Code Review and Testing

    • Conduct regular code reviews focusing on security aspects.
    • Implement static and dynamic analysis tools to identify vulnerabilities.

  • Security Frameworks and Libraries

    • Utilize established security libraries and frameworks to handle common security tasks.
    • Stay informed about security updates and best practices for these tools.

  • Documentation and Training

    • Provide developers with training on secure coding practices.
    • Maintain clear documentation of security policies and practices.

Input Validation

  • Validate and sanitize all user inputs to avoid malicious data.
  • Prefer whitelisting (defining acceptable inputs) over blacklisting (preventing known bad inputs) to enhance security.

Error Handling

  • Minimize the display of detailed error messages to end-users to prevent information leakage.
  • Securely log errors while ensuring sensitive information remains confidential.

Authentication and Access Control

  • Implement robust password policies necessitating a combination of length and complexity.
  • Enforce the use of multi-factor authentication (MFA) for high-stakes operations to bolster security.

Data Protection

  • Encrypt sensitive data both in transit (during transmission) and at rest (when stored).
  • Securely hash passwords using strong algorithms like bcrypt or Argon2 to protect against unauthorized access.

Session Management

  • Secure session identifiers by employing HTTP-only cookies to mitigate risks of cross-site scripting.
  • Enforce session expiration and ensure session invalidation occurs immediately upon user logout.

Code Dependencies

  • Regularly update and patch third-party libraries and frameworks to protect against known vulnerabilities.
  • Utilize scanning tools to detect and mitigate vulnerabilities within code dependencies.

Principle of Least Privilege

  • Assign only the necessary permissions to users and processes to limit potential abuse.
  • Conduct regular reviews and adjustments of permission settings to ensure they remain appropriate.

Secure Data Storage

  • Avoid hardcoded sensitive information in source code to prevent accidental exposure.
  • Utilize secure vaults or secret management tools for storing sensitive data safely.

Secure Communication

  • Use Transport Layer Security (TLS) or Secure Sockets Layer (SSL) protocols for secure data transmission.
  • Validate SSL certificates to defend against man-in-the-middle attacks.

Code Review and Testing

  • Perform regular code reviews emphasizing security vulnerabilities during the development process.
  • Implement both static and dynamic analysis tools to uncover potential security issues effectively.

Security Frameworks and Libraries

  • Leverage established security libraries and frameworks for managing common security tasks efficiently.
  • Stay updated on the latest security updates and best practices associated with these tools.

Documentation and Training

  • Provide developer training focused on secure coding practices and methodologies.
  • Maintain comprehensive documentation outlining security policies and practices for reference and compliance.
