# Security Documentation
|
|
|
|
## Overview
|
|
|
|
This document outlines the security features and practices implemented in the system.
|
|
|
|
## Authentication
|
|
|
|
Authentication is handled through the user accounts system. See `user-accounts.md` for details on:
|
|
- User registration
|
|
- Login/logout functionality
|
|
- Password requirements
|
|
- Session management
|
|
|
|
## Database Security
|
|
|
|
1. **SQL Injection Prevention**
|
|
- All database queries use prepared statements with parameterized queries
|
|
- Input validation and sanitization
|
|
- Use of PDO for database access
|
|
|
|
2. **Data Access Control**
|
|
- User ownership verification on all operations
|
|
- Permission checks before data access
|
|
- Proper error handling to prevent information leakage
|
|
|
|
## Database Tables
|
|
|
|
The security system uses the following tables:
|
|
|
|
1. **Rate Limits (`rate_limit`)**
|
|
- Tracks rate limiting for various operations
|
|
- User and IP tracking
|
|
- Operation type identification
|
|
- Timestamp tracking
|
|
- Attempt counting
|
|
|
|
2. **Security Events (`security_event`)**
|
|
- Records security-related events
|
|
- Event type and severity
|
|
- User and IP information
|
|
- Timestamp tracking
|
|
- Event details storage
|
|
|
|
3. **Blocked IPs (`blocked_ip`)**
|
|
- Manages IP blocking
|
|
- Block reason tracking
|
|
- Block duration
|
|
- Administrator notes
|
|
|
|
## Data Protection
|
|
|
|
1. **Passwords**
|
|
- Stored using secure hashing
|
|
- Never stored or transmitted in plain text
|
|
- Password reset functionality with secure tokens
|
|
|
|
2. **Session Security**
|
|
- Session tokens properly generated and managed
|
|
- Session timeout implementation
|
|
- Protection against session fixation
|
|
|
|
3. **Input Validation**
|
|
- Data validation on both client and server side
|
|
- Protection against XSS attacks
|
|
- Content type verification
|
|
- Size limits on inputs
|
|
|
|
## Access Control
|
|
|
|
1. **Resource Protection**
|
|
- User ownership verification for all resources
|
|
- Permission checks before operations
|
|
- Proper error handling for unauthorized access
|
|
|
|
2. **API Security**
|
|
- Authentication required for API access
|
|
- Rate limiting
|
|
- Input validation
|
|
- Error handling without information leakage
|
|
|
|
## Best Practices
|
|
|
|
1. **Code Security**
|
|

|
|
- Secure configuration management
|
|
|
|
2. **Data Security**
|
|
- User data protection
|
|

|
|
- Access control implementation
|
|
- Error handling without leaks
|
|
|
|
3. **Infrastructure Security**
