+# Security Policy
+
+This document outlines how security vulnerabilities should be reported, handled, and disclosed for **SysMood**.
+
+---
+
+## Supported Versions
+
+We actively maintain only the **latest stable release** of SysMood.  
+Older versions do **not** receive security patches.
+
+| Version | Supported |
+|----------|------------|
+| Latest |  Yes |
+| Older releases |  No |
+
+Please upgrade to the latest version before reporting any issues.
+
+---
+
+## Reporting a Vulnerability
+
+If you discover a vulnerability or security risk in SysMood, **do not open a public GitHub issue**.
+
+Instead, please:
+
+1. **Email the maintainer directly**  
+
+2. Provide as much detail as possible:
+   - Description of the issue  
+   - Steps to reproduce (if available)  
+   - Potential impact or exploit scenario  
+   - Any suggested fix or mitigation  
+
+We aim to acknowledge your report **within 72 hours**, and will work with you to validate, fix, and coordinate disclosure responsibly.
+
+---
+
+## Responsible Disclosure Guidelines
+
+Please adhere to the following principles:
+
+- **Do not publicly disclose** the vulnerability before a fix has been released.  
+- **Avoid disruptive testing** — do not run automated scans or denial-of-service attempts against public systems.  
+- **Act in good faith** to protect end users and data.  
+
+Following these practices helps keep the community safe and ensures your findings are recognized and properly credited.
+
+---
+
+## Disclosure Policy
+
+We follow a **coordinated disclosure** approach:
+
+- Once a verified fix is released, details of the vulnerability may be publicly disclosed.  
+- Credit will be given to the reporter (if requested).  
+- Until that time, all vulnerability details must remain private.
+
+---
+
+## Security Best Practices
+
+Because SysMood interacts with system-level data (CPU, memory, process states), users and contributors should follow these best practices:
+
+### For Users
+- Run SysMood in a **trusted and isolated environment**.  
+- Avoid executing the binary with **administrator/root privileges** unless strictly necessary.  
+- **Verify release integrity** — check provided SHA-256 checksums or signatures.  
+- Keep your **compiler and dependencies** (if any) up to date.  
+- Do not share or include sensitive data (API keys, credentials, etc.) in logs or builds.
+
+### For Contributors
+- Use **safe C++ practices**: bounds checking, smart pointers, input validation.  
+- Enable **compiler warnings and sanitizers** (`-Wall -Wextra -fsanitize=address,undefined`).  
+- Avoid unsafe C-style memory operations and unchecked parsing.  
+- Review commits for potential security regressions (especially if adding file or system access features).  
+- Use GitHub’s **CodeQL** or **Clang-Tidy** for static analysis when possible.

+
+## Specific Risk Areas & Mitigations
+
+| Risk | Description | Mitigation |
+|------|--------------|-------------|
+| **Privilege escalation** | Running with elevated permissions may expose system data. | Run with least privilege. Document any required permissions. |
+| **Memory safety** | Buffer overflows or invalid reads in native code. | Use safe libraries, smart pointers, sanitizers, and code review. |
+| **Output injection** | Unsanitized console output or file writes. | Sanitize dynamic strings and avoid interpreting user input as commands. |
+| **Sensitive logging** | Logging internal system info or PII. | Avoid unnecessary logging; redact sensitive details. |
+| **Binary integrity** | Users running tampered executables. | Publish checksums or signatures for official releases. |
+

+
+## Acknowledgments
+
+We sincerely thank community members who report vulnerabilities responsibly.  
+Your help makes SysMood safer for everyone.
