# Security Policy

## 🔒 Security Features

This Church Membership System implements multiple security layers to protect your data:

### 1. Authentication & Authorization
- **Password Hashing**: All passwords are hashed using bcrypt (HASH_ALGO)
- **Session Management**: Secure PHP sessions with timeout (1 hour default)
- **Access Control**: Role-based and hierarchical access enforcement
- **Login Tracking**: Last login timestamps and activity monitoring

### 2. Database Security
- **Prepared Statements**: All queries use PDO prepared statements
- **SQL Injection Prevention**: No direct SQL concatenation
- **Input Sanitization**: All user inputs are sanitized
- **Indexed Queries**: Optimized for performance and security

### 3. Application Security
- **XSS Protection**: Output escaping for all user-generated content
- **CSRF Protection**: Ready for token-based CSRF prevention
- **File Upload Validation**: Type and size restrictions
- **Directory Listing**: Disabled via .htaccess
- **Sensitive File Protection**: .htaccess rules for config files

### 4. Audit & Monitoring
- **Activity Logging**: All user actions are logged
- **IP Address Tracking**: Source IP logged for all actions
- **User Agent Logging**: Browser/device information captured
- **Security Incident Tracking**: Failed login attempts monitored

## 🛡️ Security Best Practices

### For Administrators
