Module security_context 

Security Context Entity

The SecurityContext entity manages security-related information and access control for pipeline processing operations. It enforces security policies, tracks permissions, and maintains audit trails for secure data processing.

Overview

The security context provides:

• Access Control: Permission-based authorization for operations
• Security Levels: Hierarchical classification of data sensitivity
• Audit Tracking: Session management and operation logging
• Key Management: Integration with encryption key infrastructure
• Policy Enforcement: Validation of security requirements

Security Model

The system implements a multi-layered security model:

Permission-Based Access Control

Fine-grained permissions control specific operations:

• Read, Write, Execute for basic file operations
• Encrypt, Decrypt for cryptographic operations
• Compress, Decompress for data transformation
• Admin for administrative functions
• Custom permissions for extensibility

Hierarchical Security Levels

Data classification from Public to TopSecret:

• Public: No restrictions, publicly accessible
• Internal: Internal use only, basic protection
• Medium: Moderate sensitivity, controlled access
• Confidential: High sensitivity, restricted access
• Secret: Very high sensitivity, need-to-know basis
• TopSecret: Maximum sensitivity, highest protection

Session Management

Each context maintains a unique session for audit trails and tracking.
