Minimum File & Registry Rights
For Advanced Users of The Satoshi Terminal
Purpose and Scope
This document outlines the implementation, management, and best practices for configuring Minimum File & Registry Rights in The Satoshi Terminal. These rights are established to enforce Principle of Least Privilege (PoLP), ensuring that processes, users, and applications access only the files and registry keys necessary for their function. This approach mitigates security risks, reduces attack surfaces, and ensures compliance with industry standards such as ISO/IEC 27001, NIST SP 800-53, and CIS Benchmarks.
Conceptual Framework
File System Access Rights:
Defines granular permissions at the file and directory level.
Supports read, write, execute, and traversal permissions based on NTFS standards.
Registry Rights Management:
Regulates access to Windows Registry hives and keys.
Enforces secure defaults while enabling application-specific overrides.
Dynamic Policy Enforcement:
Monitors changes in file and registry permissions in real-time.
Automatically rolls back unauthorized modifications.
Key Objectives
Minimize Attack Surface: Restrict access to critical resources, reducing exposure to malicious activity.
Ensure Operational Integrity: Prevent accidental or unauthorized modifications to essential files and registry entries.
Maintain Compliance: Align with regulatory and organizational security policies.
File Permissions Overview
1. Permission Types
Read (R): Allows viewing the contents of a file or directory.
Write (W): Grants the ability to modify file contents.
Execute (X): Permits execution of binary files or traversal of directories.
Delete (D): Allows deletion of files or directories.
2. Permission Levels
Full Control: All permissions combined; generally restricted to administrators.
Modify: Grants read, write, and delete permissions.
Read & Execute: Combines read and execute for application compatibility.
Write: Limited to file or directory modification.
Registry Permissions Overview
1. Registry Hives
HKEY_LOCAL_MACHINE (HKLM): System-wide settings and configurations.
HKEY_CURRENT_USER (HKCU): User-specific settings.
HKEY_CLASSES_ROOT (HKCR): File type associations and COM objects.
HKEY_USERS (HKU): Configuration data for all user accounts.
HKEY_CURRENT_CONFIG (HKCC): Current hardware profile configurations.
2. Access Levels
Query Value: Read a registry key or value.
Set Value: Modify a registry value.
Create Subkey: Add a new key under an existing one.
Delete: Remove a registry key or value.
Enumerate Subkeys: List all subkeys under a given key.
Implementation Details
1. File Rights Configuration
1.1. Tools for Configuration
Windows File Explorer:
Right-click a file or directory → Properties → Security tab → Configure permissions.
Command-Line Tools:
icacls: Modify and view permissions.Example:
takeown: Take ownership of files. Example:
1.2. Recommended Permissions for The Satoshi Terminal
C:\SatoshiTerminal
Administrators
Full Control
Required for installation and updates.
C:\SatoshiTerminal\configs
System
Read & Write
Secure access to configuration files.
C:\SatoshiTerminal\logs
Users
Read Only
Prevents unauthorized log modifications.
2. Registry Rights Configuration
2.1. Tools for Configuration
Registry Editor (regedit.exe):
Navigate to a registry key → Permissions → Configure access.
Command-Line Tools:
reg addandreg delete: Modify registry keys.Example:
PowerShell:
Example:
2.2. Recommended Registry Key Permissions
HKLM\Software\SatoshiTerminal
Administrators
Full Control
Required for software management.
HKLM\Software\SatoshiTerminal\Config
System
Read & Write
System-wide configuration access.
HKCU\Software\SatoshiTerminal
Users
Read & Modify
User-specific preferences and settings.
Dynamic Policy Enforcement
1. Real-Time Monitoring
Utilizes Event Tracing for Windows (ETW) to track changes in file and registry rights.
Monitors the following events:
Unauthorized
icaclsortakeownusage.Registry key creation or deletion in protected paths.
2. Automatic Rollback
Any unauthorized modification triggers:
Alert notifications via email/SMS.
Reversion of changes using stored baselines.
3. Policy Enforcement Tools
Group Policy Objects (GPOs):
Centralized enforcement of file and registry permissions.
Example: Prevent non-admins from modifying
HKLM\Software\SatoshiTerminal.
Best Practices
1. General Guidelines
Assign permissions to groups instead of individual users.
Avoid granting "Full Control" unless strictly necessary.
Regularly audit file and registry rights.
2. Hardening Recommendations
Enable Mandatory Integrity Control (MIC):
Ensures that even trusted processes cannot escalate privileges arbitrarily.
Implement AppLocker Policies:
Restricts executable permissions based on file paths.
Advanced Troubleshooting
1. Diagnostic Commands
List Effective Permissions:
View Registry ACLs:
2. Common Issues
"Access Denied" Errors:
Verify that inheritance is enabled for subkeys or directories.
Permissions Misconfiguration:
Restore defaults using:
3. Escalation Path
Gather logs from Event Viewer under Security and Application.
Contact Level 2 support with detailed findings.
By strictly adhering to the Minimum File & Registry Rights outlined in this document, you ensure that The Satoshi Terminal operates securely while reducing risks of unauthorized access or tampering. Proper configuration and ongoing management of these rights are critical to safeguarding sensitive cryptocurrency data and maintaining regulatory compliance.
