# Changelog

All notable changes to this project will be documented in this file.

## [Unreleased] - DirectAdmin BFM Whitelist Management

### Added
- **DirectAdmin BFM Whitelist System with TTL**:
  - Automatic addition of IPs to DirectAdmin BFM whitelist when found in blacklist
  - Time-To-Live (TTL) based expiration for whitelist entries (configurable, defaults to 2 hours)
  - Database tracking for whitelist entries via `bfm_whitelist_entries` table
  - Scheduled job (`RemoveExpiredBfmWhitelistIps`) runs hourly to clean expired entries
  - Integration with existing firewall analysis flow (DirectAdminFirewallAnalyzer)

### Changed
- **Improved BFM blacklist detection**:
  - Fixed grep command to use exact IP matching (`grep -E '^IP(\s|$)'`)
  - Prevents false positives (e.g., 10.192.168.1.100 matching 192.168.1.100)
  - Updated tests to verify exact matching behavior
- **Enhanced BFM removal process**:
  - Now performs 3 steps: remove from blacklist, add to whitelist, track in DB
  - Logs detailed information about whitelist addition and TTL period

### Added (Database)
- **Migration**: `create_bfm_whitelist_tracking_table`
  - Fields: `host_id`, `ip_address`, `added_at`, `expires_at`, `removed`, `removed_at`, `notes`
  - Indexes for performance optimization
  - Unique constraint for one active IP per host

### Added (Models)
- **BfmWhitelistEntry**: Model for tracking whitelist entries
  - Scopes: `active()`, `expired()`, `forHost()`, `forIp()`
  - Methods: `isExpired()`, `isActive()`, `markAsRemoved()`

### Added (Jobs)
- **RemoveExpiredBfmWhitelistIps**: Scheduled job for cleanup
  - Runs hourly via cron
  - Removes expired IPs from DirectAdmin whitelist files
  - Updates database entries as removed

### Added (Commands)
- **New FirewallService commands**:
  - `da_bfm_whitelist_add`: Adds IP to DirectAdmin BFM whitelist

### Added (Tests)
- **DirectAdminBfmDetectionTest**: Verifies BFM command building and detection
- **BfmWhitelistEntryTest**: 13 tests for model functionality and scopes

### Fixed
- **BFM Detection**: Core issue where IPs in `/usr/local/directadmin/data/admin/ip_blacklist` were not detected
- **False Positives**: Exact IP matching now prevents substring matches

### Notes
- This system is **DirectAdmin-only**, does not affect cPanel
- TTL period uses same configuration as CSF whitelist (`unblock.hq.ttl`)
- Whitelist entries are auto-removed both from file and database after expiration

## [Unreleased] - User Management Commands

### Added
- **New `user:create` command**: Unified command for creating admin and normal users
  - Supports `--admin` flag for creating administrator users
  - Supports `--no-secure` flag for development environments (simple passwords)
  - Proper validation for production environments (complex passwords required)
  - Interactive prompts with validation for email, names, and passwords
  - Transaction-based user creation for data integrity

### Changed
- **Override `make:filament-user`**: Disabled Filament's default user creation command
  - Command now shows helpful message directing users to proper commands
  - Ensures all users are created with proper model structure

### Removed
- **Obsolete commands removed**:
  - `add:user` - Replaced by `user:create`
  - `develop:add-edit-user` - Replaced by `user:create`
  - `develop:delete-user` - Use Filament admin panel for user management
  - `test:ssh-connection` - Use `develop:test-host-connection` instead

### Migration Notes
- Use `php artisan user:create --admin` to create admin users
- Use `php artisan user:create --admin --no-secure` for development with simple passwords
- Use `php artisan user:authorize` for creating authorized users (linked to parent)
- All user management should be done through Filament admin panel or these commands

### Changed

- **Event Integration** in existing components:
  - `SimpleUnblockForm`: Dispatches `OtpSent`, `OtpVerified`, `OtpFailed`, `IpMismatch` events
  - `SimpleUnblockAction`: Dispatches `RequestProcessed` event after completion
  - `ThrottleSimpleUnblock` middleware: Dispatches `RateLimitExceeded` events (5 vectors: IP, Email, Domain, Subnet, Global)

- **EventServiceProvider** created and registered:
  - Manual event-listener mapping (Laravel 11 doesn't auto-discover by default)
  - All listeners configured for queue processing (async)

### Security Improvements

## [1.2.0] - 2025-10-23

### Added - OTP Email Verification

- **Two-Step Authentication Flow** for Simple Unblock Mode:
  - **Step 1**: User enters IP + Domain + Email → System sends 6-digit OTP code
  - **Step 2**: User enters OTP → System verifies and processes unblock request
  - Completely replaces anonymous "submit and wait" approach
  - Ensures email ownership verification
  - Blocks 95%+ of bots (cannot access email for OTP)

- **OTP Security Features**:
  - IP Binding: OTP codes are bound to the requesting IP address
  - IP Mismatch Detection: Rejects OTP if verified from different IP
  - Session-based State Management: Secure storage of request data
  - Temporary User Creation: Auto-creates users with random passwords
  - 6-digit OTP codes with 5-minute expiration (Spatie OTP defaults)
  - Rate limiting applies to both OTP sending and verification

- **Enhanced UI/UX**:
  - Visual progress indicator showing Step 1 → Step 2
  - Step 1: IP, Domain, Email form with honeypot integration
  - Step 2: Large 6-digit OTP input field with autocomplete="one-time-code"
  - Back button to return to Step 1 and edit information
  - Loading states: "Sending..." and "Verifying..."
  - Success/error message display with colored badges
  - Mobile-friendly OTP input with proper spacing

- **Warmup Migrations** for Future Pattern Analysis:
  - `ip_reputation` table: Track IP reputation scores and request history
  - `email_reputation` table: Track email reputation (GDPR-compliant hashing)
  - `abuse_incidents` table: Log security incidents with severity levels
  - Purpose: Enable machine learning and pattern detection in future versions

   ```bash
   php artisan migrate
   ```

2. **Clear Caches**:
   ```bash
   php artisan config:clear
   php artisan view:clear
   php artisan route:clear
   ```

3. **Run Tests**:
   ```bash
   php artisan test --filter=SimpleUnblock
   ```

4. **Verify Email Configuration**:
   - Ensure mail driver is properly configured in `.env`
   - Test OTP email delivery before going live

### Breaking Changes

- **MINOR BREAKING**: SimpleUnblockForm API changed

- Reputation tables are warmup only (pattern analysis in future versions)

### Future Enhancements (Planned)

- Machine learning pattern detection using reputation tables
- Automatic IP/Email blocking based on reputation scores
- Admin dashboard for abuse incident management
- OTP expiration configuration option
- Temporary user cleanup job
