We actively support the following versions of Helios with security updates:

We take security vulnerabilities seriously. If you discover a security vulnerability in Helios, please report it to us as described below.

Please do not report security vulnerabilities through public GitHub issues.

Instead, please report security vulnerabilities by emailing our security team at:

Email: security@cloudshuttle.com

When reporting a security vulnerability, please include:

1. Description: A clear description of the vulnerability
2. Steps to Reproduce: Detailed steps to reproduce the issue
3. Impact: The potential impact of the vulnerability
4. Affected Versions: Which versions of Helios are affected
5. Proof of Concept: If possible, include a minimal proof of concept
6. Suggested Fix: If you have ideas for how to fix the issue

1. Acknowledgment: You will receive an acknowledgment within 24 hours
2. Initial Assessment: We will provide an initial assessment within 72 hours
3. Regular Updates: We will keep you informed of our progress
4. Resolution: We will work with you to resolve the issue
5. Disclosure: We will coordinate with you on public disclosure

• Initial Response: Within 24 hours
• Status Update: Within 72 hours
• Resolution: Within 30 days (for critical vulnerabilities)
• Public Disclosure: Within 90 days (coordinated with reporter)

1. Keep Updated: Always use the latest stable version of Helios
2. Review Dependencies: Regularly update your project dependencies
3. Validate Input: Always validate and sanitize user input
4. Use HTTPS: Serve your applications over HTTPS in production
5. Content Security Policy: Implement appropriate CSP headers
6. Regular Audits: Run security audits on your dependencies

1. Secure Coding: Follow secure coding practices
2. Input Validation: Validate all inputs and outputs
3. Error Handling: Implement proper error handling without information leakage
4. Dependency Management: Keep dependencies updated and audit regularly
5. Code Review: All code changes should be reviewed for security issues
6. Testing: Include security testing in your development process

Helios uses WebGPU for high-performance rendering. Security considerations include:

• GPU Memory Access: WebGPU provides direct GPU memory access
• Shader Validation: All shaders are validated before execution
• Resource Limits: GPU resources are limited to prevent abuse
• Sandboxing: WebGPU runs in a sandboxed environment

Helios compiles to WebAssembly (WASM) for web deployment:

• Memory Safety: Rust's memory safety prevents common vulnerabilities
• Bounds Checking: Array and buffer access is bounds-checked
• Stack Protection: Stack overflow protection is enabled
• Control Flow Integrity: CFI is enabled to prevent ROP attacks

Helios processes data using Polars and DataFusion:

• SQL Injection: All SQL queries are parameterized
• Data Validation: Input data is validated before processing
• Memory Limits: Processing is limited to prevent DoS attacks
• Access Control: Data access is controlled and audited

• Security researchers discover vulnerabilities
• Vulnerabilities are reported through our security email
• We acknowledge receipt and begin investigation

• We assess the severity and impact of the vulnerability
• We determine affected versions and components
• We assign a severity level (Critical, High, Medium, Low)

• We develop a fix for the vulnerability
• We test the fix thoroughly
• We prepare a security advisory

• We coordinate with the reporter on disclosure timing
• We release the fix and security advisory
• We update our security documentation

• We monitor for any issues with the fix
• We update our security processes if needed
• We recognize the reporter (if desired)

• Remote code execution
• Privilege escalation
• Data breach or exposure
• Authentication bypass

• Denial of service
• Information disclosure
• Cross-site scripting (XSS)
• Cross-site request forgery (CSRF)

• Local privilege escalation
• Information leakage
• Input validation issues
• Performance degradation

• Minor information disclosure
• Cosmetic issues
• Best practice violations
• Documentation issues

Security advisories are published for vulnerabilities that meet our severity criteria:

• Critical and High: Always published
• Medium: Published if they affect many users
• Low: Published if they have significant impact

Advisories include:

• Description of the vulnerability
• Affected versions
• Steps to reproduce
• Impact assessment
• Mitigation steps
• Fix information

We follow responsible disclosure practices:

1. Private Reporting: Vulnerabilities are reported privately first
2. Coordinated Disclosure: We coordinate with reporters on disclosure timing
3. Adequate Time: We provide adequate time for fixes to be developed and deployed
4. Credit: We give credit to security researchers who report vulnerabilities
5. No Retaliation: We do not take legal action against good-faith security research

We encourage security research on Helios:

• Scope: Research on Helios and its dependencies
• Methods: Use of automated tools, manual testing, and code review
• Reporting: Report findings through our security email
• Recognition: We recognize security researchers in our advisories

The following are out of scope for security research:

• Social engineering attacks
• Physical attacks
• Attacks on third-party services
• Denial of service attacks that don't demonstrate a vulnerability
• Issues that require physical access to the target system

We use several static analysis tools:

• Clippy: Rust linter for common issues
• cargo-audit: Security audit of dependencies
• cargo-deny: License and security policy enforcement
• semgrep: Security-focused static analysis

We perform dynamic analysis:

• Fuzzing: Automated fuzzing of input processing
• Penetration Testing: Regular security assessments
• Dependency Scanning: Automated scanning of dependencies
• Container Scanning: Security scanning of Docker images

• OWASP Top 10
• Rust Security Guidelines
• WebGPU Security Model
• WASM Security

For security-related questions or concerns:

• Security Email: security@cloudshuttle.com
• General Contact: contact@cloudshuttle.com
• GitHub Security: Use GitHub's private vulnerability reporting feature
