Security Daemon (securityd)

Overview

The Security Daemon (securityd) will manage system security policies, access control, and authentication services for FreeWorld OS. Currently, security functionality is provided by Node.js modules, but a dedicated daemon is planned for kernel-level security operations.

Planned Functions

• Access Control Enforcement: Enforce file and system access permissions
• User Permission Management: Manage user permissions and groups
• Security Policy Enforcement: Enforce system-wide security policies
• Audit Logging: Log security events for auditing
• Intrusion Detection: Detect and respond to security threats
• Session Management: Manage user sessions and tokens
• ACL Management: Manage Access Control Lists

Current Implementation

Security functionality is currently provided by Node.js modules:

• system/security.js: SecurityManager class with session and token management
• system/security-manager.js: Extended security management functionality

These modules provide:

• Session creation and management
• Access token generation
• Privilege calculation
• ACL (Access Control List) management
• User/group management

Future Daemon Implementation

The securityd daemon will:

• Run as a privileged system daemon
• Provide kernel-level security enforcement
• Handle security policy updates
• Coordinate with kernel security subsystem
• Provide IPC interface for security operations

Integration

securityd will integrate with:

• Kernel Security Subsystem: Low-level security enforcement
• SecurityManager (Node.js): High-level security API
• logd: Security audit logging
• freeworldlogon: Authentication services
