Security Overview

Smart Shelf implements a comprehensive security framework designed to protect sensitive business data, ensure user privacy, and maintain system integrity. The security model is built on multiple layers of protection, from network-level security to application-level controls.

Security Principles

Defense in Depth

Our security strategy employs multiple layers of protection to ensure that if one security control fails, others are in place to maintain protection:

• Network Layer: Firewalls, DDoS protection, intrusion detection
• Application Layer: Input validation, authentication, authorization
• Data Layer: Encryption, access controls, data masking
• Infrastructure Layer: Secure configurations, monitoring, logging

Least Privilege Access

Every user and system component receives only the minimum level of access required to perform their functions:

• Users receive minimum necessary permissions
• Role-based access control (RBAC) implementation
• Regular permission audits and reviews
• Temporary privilege escalation when needed
• Automated privilege de-provisioning

Zero Trust Architecture

We implement a "never trust, always verify" approach:

• No implicit trust based on network location
• Continuous verification of user identity and device health
• Encrypted communication at all levels
• Micro-segmentation of network resources
• Real-time risk assessment

Data Privacy by Design

Privacy protection is built into every aspect of our system:

• Personal data protection by default
• Data minimization principles
• Purpose limitation for data processing
• Privacy impact assessments
• User consent management
