Security¶

Overview¶

The Gustaffo Reservations Application implements a comprehensive security framework to protect sensitive data and ensure secure operations. This document outlines the security measures implemented across different layers of the application.

Authentication and Authorization¶

User Authentication¶

The application uses OAuth 2.0 and OpenID Connect for authentication:

JWT (JSON Web Token) based authentication
Token-based session management
Multi-factor authentication support for administrative users
Password policies enforcing strong passwords
Account lockout after multiple failed login attempts

Authorization¶

Role-based access control (RBAC) is implemented to restrict access to resources:

Predefined roles with specific permissions (Admin, Manager, Staff, User)
Fine-grained permission system for API endpoints
Resource-based access control for specific entities
Hierarchical permission inheritance

Data Protection¶

Data Encryption¶

All data in transit is encrypted using TLS 1.2+
Sensitive data at rest is encrypted using AES-256
Database encryption for PII (Personally Identifiable Information)
Encryption key management using a secure key vault

PCI DSS Compliance¶

For payment card processing, the system adheres to PCI DSS requirements:

No storage of full credit card numbers
Tokenization of payment methods
Secure integration with PCI-compliant payment processors
Regular security assessments and penetration testing

Network Security¶

API Security¶

Input validation on all API endpoints
Request rate limiting to prevent abuse
API versioning to manage changes securely
CORS (Cross-Origin Resource Sharing) configuration

Infrastructure Security¶

Web Application Firewall (WAF) to protect against common attacks
Network segmentation to isolate components
VPC (Virtual Private Cloud) for cloud deployments
IP whitelisting for administrative access

Secure Development Practices¶

Secure SDLC¶

Security requirements defined at project initiation
Threat modeling during design phase
Static Application Security Testing (SAST)
Dynamic Application Security Testing (DAST)
Regular security code reviews

Dependency Management¶

Automated scanning of dependencies for vulnerabilities
Regular updates of libraries and frameworks
Software Bill of Materials (SBOM) maintenance

Monitoring and Incident Response¶

Security Monitoring¶

Real-time monitoring for suspicious activities
Centralized logging of security events
Intrusion detection and prevention systems
Automated alerts for security incidents

Incident Response¶

Documented incident response procedures
Defined roles and responsibilities
Regular incident response drills
Post-incident analysis and improvement

Compliance¶

Data Protection Regulations¶

The application is designed to comply with relevant data protection regulations:

GDPR (General Data Protection Regulation)
CCPA (California Consumer Privacy Act)
Local data protection laws in operating jurisdictions

Compliance Controls¶

Data minimization practices
Data retention policies
Privacy by design principles
User consent management
Subject access request handling

Physical Security¶

Infrastructure¶

Secure hosting in SOC 2 compliant data centers
Physical access controls to server environments
Environmental controls (power, cooling, fire suppression)
Redundant infrastructure for critical components

Security Testing¶

Regular Assessments¶

Quarterly vulnerability scans
Annual penetration testing
Regular security architecture reviews
Third-party security audits

Business Continuity and Disaster Recovery¶

Regular data backups with encryption
Offsite backup storage
Documented disaster recovery procedures
Regular recovery testing

Training and Awareness¶

Security awareness training for all employees
Specialized security training for developers
Regular phishing simulation exercises
Security considerations in onboarding and offboarding processes
