Responsible Disclosure Policy

Overview

The Savitri Network Responsible Disclosure Policy establishes a framework for security researchers to report vulnerabilities in a responsible manner while ensuring proper protection for both researchers and the Savitri Network ecosystem. This policy encourages ethical security research and facilitates the timely remediation of discovered vulnerabilities.

Technology Choice Rationale

Why Responsible Disclosure Policy

Problem Statement: Security researchers need clear guidelines for reporting vulnerabilities while protecting both researchers and the ecosystem from premature disclosure.

Chosen Solution: Comprehensive responsible disclosure framework with clear reporting procedures, timelines, and protection measures.

Rationale:

• Researcher Protection: Legal protection for good-faith security research
• Ecosystem Safety: Prevent exploitation of vulnerabilities before patches
• Clear Process: Well-defined reporting and remediation procedures
• Transparency: Public disclosure of fixed vulnerabilities

Expected Results:

• Increased vulnerability reporting from security researchers
• Faster remediation of security issues
• Reduced risk of vulnerability exploitation
• Stronger security through collaborative research
