BUSINESS POSTURE

  • Business Priorities and Goals:
    • Provide a flexible and extensible Content Management System (CMS) platform for web developers and designers.
    • Offer a user-friendly interface for content management.
    • Enable rapid development of websites and web applications.
    • Foster a strong community around the platform.
    • Maintain a stable and reliable open-source CMS solution.
  • Business Risks:
    • Security vulnerabilities in the platform could damage reputation and user trust.
    • Lack of community support or developer adoption could lead to project stagnation.
    • Competition from other CMS platforms.
    • Difficulty in maintaining compatibility with evolving web technologies.
    • Open-source nature may lead to unauthorized modifications or distributions.

SECURITY POSTURE

  • Existing Security Controls:
    • security control: Secure Software Development Lifecycle (SSDLC) - Implemented through community contributions, code reviews (implicitly via pull requests), and issue tracking on GitHub.
    • security control: Input validation - Implemented within the OctoberCMS core and framework to sanitize user inputs and prevent common web vulnerabilities.
    • security control: Authentication and Authorization - Implemented within the OctoberCMS core, providing user and role-based access control to the backend and frontend functionalities.
    • security control: Protection against common web vulnerabilities - Framework based on Laravel, which includes built-in protection against common web vulnerabilities like CSRF, XSS, and SQL injection.
    • security control: Regular security updates - Provided by the OctoberCMS team and community, addressing reported vulnerabilities.
  • Accepted Risks:
    • accepted risk: Vulnerabilities in third-party plugins - OctoberCMS relies on a plugin ecosystem, and security of these plugins is dependent on individual plugin developers.
    • accepted risk: Misconfiguration by users - Users deploying and configuring OctoberCMS might introduce security misconfigurations.
    • accepted risk: Delayed patching by users - Users might not apply security updates promptly, leaving systems vulnerable.
  • Recommended Security Controls:
    • security control: Automated Security Scanning - Implement automated SAST and DAST scanning in the CI/CD pipeline for core OctoberCMS development.
    • security control: Dependency Scanning - Implement dependency scanning to identify and manage vulnerabilities in third-party libraries used by OctoberCMS.
    • security control: Security awareness training for core developers and plugin developers - Enhance security knowledge and best practices among contributors.
    • security control: Bug bounty program - Establish a bug bounty program to incentivize security researchers to find and report vulnerabilities.
    • security control: Penetration testing - Conduct regular penetration testing on OctoberCMS to identify potential weaknesses.
  • Security Requirements:
    • Authentication:
      • Requirement: Secure authentication mechanism for backend administrators and frontend users.
      • Requirement: Support for strong password policies and multi-factor authentication (MFA) as an option.
      • Requirement: Protection against brute-force attacks and account enumeration.
    • Authorization:
      • Requirement: Role-based access control (RBAC) to manage permissions for backend functionalities.
      • Requirement: Granular permission management for different areas of the CMS.
      • Requirement: Secure authorization checks throughout the application to prevent unauthorized access to resources and functionalities.
    • Input Validation:
      • Requirement: Comprehensive input validation and sanitization for all user-provided data.
      • Requirement: Protection against common injection attacks (SQL injection, XSS, command injection, etc.).
      • Requirement: Use of parameterized queries or ORM to prevent SQL injection.
      • Requirement: Output encoding to prevent XSS vulnerabilities.
    • Cryptography:
      • Requirement: Secure storage of sensitive data, including passwords and API keys, using strong encryption algorithms.
      • Requirement: Use of HTTPS for all communication to protect data in transit.
      • Requirement: Secure handling of cryptographic keys and secrets.

    • Plugin Ecosystem: Ensuring the security and reliability of the plugin ecosystem, as it extends core functionality.
  • Data Sensitivity:
    • User Data: User accounts, profiles, and potentially personal information collected through forms. Sensitivity: Medium to High (depending on data collected and regulatory requirements like GDPR).
    • Website Content: Text, images, media files, and website structure. Sensitivity: Low to Medium (business impact if compromised or lost).
    • Configuration Data: Database credentials, API keys, and system settings. Sensitivity: High (critical for system security and access).
    • Application Code: Source code of OctoberCMS, themes, and plugins. Sensitivity: Medium to High (intellectual property, potential for vulnerability exploitation if exposed).

QUESTIONS & ASSUMPTIONS

  • Questions:
    • What are the specific compliance requirements for OctoberCMS deployments (e.g., GDPR, PCI DSS)?
    • Are there specific industry verticals or use cases that OctoberCMS primarily targets, which might influence security priorities?
    • What is the process for security incident response and vulnerability disclosure for OctoberCMS?
    • Are there any existing security policies or guidelines for OctoberCMS development and deployment?
  • Assumptions:
    • BUSINESS POSTURE: The primary business goal is to provide a widely adopted and trusted open-source CMS platform. Security and community trust are critical for achieving this goal.
    • SECURITY POSTURE: OctoberCMS follows common security practices for web applications and open-source projects. Security is a shared responsibility between the core team, plugin developers, and users.
    • DESIGN: The design assumes a typical three-tier web application architecture with web servers, application servers, and database servers. Deployment is flexible and can be adapted to various environments, including cloud and on-premise. Build process includes basic security checks but could be enhanced with more comprehensive automated security testing.
