+## Try it first in a virtual machine
+
+**Curious, but not ready to replace your current operating system?** Start with
+Sovran_SystemsOS in a virtual machine (VM). A VM runs Sovran_SystemsOS in a
+window on your existing Windows, macOS, or Linux computer, using a virtual disk
+file instead of your computer's internal drive. You can explore the desktop,
+Sovran Hub, Sparrow, Bisq, and the installation experience before changing how
+you use any physical machine.
+
+This is a low-commitment way to decide whether Sovran_SystemsOS is right for
+you:
+
+- **Keep your current OS.** Closing or deleting the VM leaves the host operating
+  system in place.
+- **Learn at your own pace.** Familiarize yourself with the desktop and tools
+  without needing to make it your daily computer on day one.
+- **Choose your next step with confidence.** When you are ready, install it on
+  a dedicated computer, or keep using the VM as a learning environment.
+
+You can use the same ISO with [VirtualBox](https://www.virtualbox.org), VMware,
+QEMU/KVM, Proxmox, and similar x86_64 VM software. For a first look, select
+**Desktop Only**, allocate at least **8 GB RAM**, and create a **256 GB or
+larger dynamically allocated virtual disk**. The full VM setup and installer
+requirements are in [Installing in a virtual machine](#installing-in-a-virtual-machine-optional).
+
+> **A VM is for evaluation and learning, not a substitute for a dedicated,
+> hardened setup.** Do not use a trial VM to hold meaningful Bitcoin, recovery
+> phrases, passwords, or other sensitive data. Avoid attaching physical drives
+> to the VM, and be deliberate about shared folders, clipboard sharing, and
+> network settings. The installer only changes the disk you select, but you
+> should always review VM disk selections before confirming an install.

+# Security Policy (SECURITY.md)
+
+This document outlines the security policy, vulnerability disclosure process, threat model, and security best practices for **Sovran_SystemsOS**.
+
+---
+
+## 1. Supported Versions
+
+We actively monitor and patch security vulnerabilities in Sovran_SystemsOS. Because the operating system is built on [NixOS](https://nixos.org), stable releases receive security updates backported from upstream Nixpkgs as well as our custom software updates.
+
+| Version | Supported | Notes |
+|:---|:---:|:---|
+| **1.0.x** (Stable) |  Yes | Active stable release line. Patches are backported regularly. |
+| **staging-dev** |  Yes | Development line; updated frequently but may contain untested code. |
+| **Legacy (< 1.0.0)** |  No | Please upgrade to the latest stable release to ensure you have active security updates. |
+
+---
+
+## 2. Reporting a Vulnerability
+
+We take the security of self-custody systems, private clouds, and communications servers extremely seriously. If you discover a vulnerability, **please do not open a public issue, forum thread, or submit a public pull request.** 
+
+Instead, report vulnerabilities privately through one of the following secure channels:
+
+1. **Email:** Send an encrypted or plain-text email to [support@sovransystems.com](mailto:support@sovransystems.com).
+   - If sending sensitive information, please contact us first to establish a secure PGP-encrypted communication channel.
+2. **GitHub Private Vulnerability Reporting:** If you are viewing this on GitHub, you can report vulnerabilities privately via the **Security** tab of this repository under **Vulnerability reporting**.
+
+### What to Include in a Report:
+To help us triage and resolve the issue quickly, please include:
+- A clear description of the vulnerability and its potential impact.
+- Step-by-step instructions to reproduce the issue (including any scripts or configuration snippets).
+- The version of Sovran_SystemsOS you tested (found in the Hub header or `/etc/nixos/VERSION`).
+- Any potential remediation steps or suggestions you may have.
+
+### Our Response and Disclosure Process:
+1. **Acknowledgment:** We will acknowledge receipt of your report within **24–48 hours** and provide a tracking reference.
+2. **Triage:** We will investigate and verify the vulnerability privately. We may reach out to you for clarifying details.
+3. **Remediation:** If verified, we will develop a patch on a private security branch.
+4. **Release:** We will coordinate a release date with you and publish the patch to Gitea `stable` and GitHub `main`.
+5. **Advisory:** A public security advisory will be published, giving full credit to you for the discovery (unless you request anonymity).
+
+We ask that you practice **coordinated vulnerability disclosure**, giving us reasonable time to patch the vulnerability before disclosing it publicly to protect other operators' funds and data.
+
+---
+
+## 3. The Sovran_SystemsOS Security Architecture
+
+Understanding our underlying threat model and architectural decisions will help you evaluate the system's security.
+
+### A. Local-First Threat Model
+- **No Cloud Dependency:** Your data, keys, and credentials live entirely on your physical hardware.
+- **Local network Hub Access:** The Sovran Hub is served directly on your local network (`sovransystemsos.local`). It is protected by authentication and **never** automatically exposed to the public internet.
+- **Localhost Auto-Login:** Auto-login to the Hub is restricted strictly to local connections from `127.0.0.1` or `::1` (e.g., when accessing it directly from the local GNOME desktop). LAN and WAN clients must authenticate via password.
+
+### B. Declarative & Reproducible NixOS Foundation
+- **No Supply Chain Drift:** Dependencies, packages, and system components are strictly pinned using Nix flakes (`flake.lock`).
+- **Reproducible Integrity Checks:** Operators can verify system integrity at any time via the Hub (`/api/security/verify-integrity`), which runs `nix store verify --all` to check binary consistency and rebuilds the system state from local files to guarantee it matches the expected configuration.
+- **Default-Hardened Base:** Firewalls are enabled by default (`networking.firewall.enable = true`), public SSH and remote desktop are disabled by default, and legacy kernel modules like `rxrpc` are blacklisted to reduce the kernel's attack surface.
+
+### C. Restricted Tech Support ("Zero-Trust Support")
+To prevent support staff or malicious actors from accessing your private wallets, the operating system employs a unique **"Zero-Trust Support"** architecture:
+- **Restricted System Account:** Support sessions use a restricted, non-root account (`sovran-support`) with heavily scoped shell access and limited `sudo` privileges (restricted strictly to viewing logs, editing configuration, and rebuilding or restarting services).
+- **POSIX ACL Wallet Lockout:** Enabling support immediately triggers POSIX ACLs (`setfacl -m u:sovran-support:---`) to block the support user from reading, writing, or traversing sensitive directories (such as `/etc/nix-bitcoin-secrets`, `/var/lib/bitcoind`, `/var/lib/lnd`, and `/home`).
+- **User-Controlled Timed Unlock:** Support staff can *only* access wallet files if the operator explicitly grants a time-limited unlock from the Hub interface. This unlock automatically expires, re-locking the directories.
+- **Tamper-Evident Auditing:** All support actions (enabling, disabling, wallet unlocking, or locking) are logged in a tamper-evident audit trail (`/var/log/sovran-support-audit.log`) readable directly by the operator.
+
+### D. Native Cryptographic Isolation
+- **Tor Network Integration:** Upstream Bitcoin services (Knots/Core, Electrs, LND) utilize native Tor integration, preventing your home IP address from leaking to the public network or third-party node providers.
+- **Isolated Lightning Wallets:** Nostr Wallet Connect (NWC) uses isolated, sandboxed Lightning wallets with specific spending limits and access presets (e.g., receive-only), keeping your main node funds completely isolated from individual apps.
+
+---
+
+## 4. Security Best Practices for Operators (Users)
+
+No software can provide absolute security. You are the ultimate sovereign of your machine. Follow these best practices to keep your system and assets secure:
+
+### 🔑 1. Split Wallet Entropy
+When setting up a Bitcoin wallet, **generate your two entropy sources on separate, unconnected hardware**:
+- **Seed Phrase:** Generated by Sparrow Wallet on your Sovran_SystemsOS machine.
+- **BIP-39 Passphrase (128-bit):** Generated on a separate device (e.g., a GrapheneOS phone using a trusted password generator or offline Diceware dice).
+- *Why?* If either device is compromised, your wallet remains secure because an attacker needs **both** independent sources of randomness to recover it.
+
+### 💾 2. Implement a Robust Backup Strategy
+- **Off-Machine Backups:** Never store your only wallet backups, seed phrases, or descriptor backups on the same computer as your running wallet.
+- **Descriptor & Channel Backups:** If using Lightning (LND), regularly back up your Static Channel Backups (SCB) and store them off-site. A node hardware failure can permanently lock up channel funds without a fresh SCB.
+- **Ext4 Backups:** If using the Hub's Manual Backup utility, ensure you are backing up to a dedicated **ext4-formatted** external drive. This preserves Linux-native security metadata, permissions, and POSIX ACLs.
+
+### 🛡️ 3. Maintain Network and Access Hygiene
+- **Public SSH Off:** Keep SSH remote access disabled in the Hub unless you actively need it. If enabled, Fail2Ban is active, but you should still enforce a strong system password.
+- **Strong Diceware Passwords:** Ensure the system `free` and `root` users have strong passphrases. Avoid re-using passwords across services.
+- **Guest Networks:** Do not access the Sovran Hub over public or guest Wi-Fi networks. These networks often lack isolation, exposing local network traffic to other devices.
+- **Disable RDP When Done:** Turn off Remote Desktop (RDP) once your administrative session is finished.
+
+### 🧑‍💻 4. Hardening Support Sessions
+If you require technical support from Sovran Systems:
+- **Enable SSH and Support on-demand:** Only enable SSH Remote Access and Support sessions when actively working with a technician, and **disable** them immediately when the session is over.
+- **Confirm Removal:** The Hub's support page includes a "Verify Removal" feature. Always use it to ensure public keys have been fully stripped from the system.
+- **Restrict Wallet Access:** Only unlock your wallet directories if absolutely necessary for the support session, and choose the shortest possible duration. Re-lock manually as soon as the troubleshooting steps are complete.
+- **Review Audit Logs:** Periodically inspect the support audit log via the Hub interface to review exactly when support sessions were toggled or unlocked.

Contributor	8a766181de	fix: hash root password instead of storing in clear text (CWE-312) - Replace plain-text write of new_root_password in api_security_reset() with scrypt-hashed storage via _hash_password(), matching how the free password is already handled. - Return new_root_password in the API response so the user sees it once before it is irreversibly hashed on disk. - Teach _resolve_credential() to detect scrypt hashes and display a human-readable placeholder instead of raw hex in the Hub credentials UI. - Harden root-password-setup systemd service: if the secrets file already contains a hash, skip chpasswd so a manual restart never sets the hash as the literal login password.	2026-08-07 12:34:13 -05:00
