Context-Aware Security adapts security policies and controls based on situational factors such as user location, device type, network environment, time of access, and application usage patterns. This approach provides more precise security decisions by considering the full context of user activities rather than applying static rules.
Core Context Dimensions
User Context
Information about the user and their current situation: - Identity and Role: User identity, job function, and organisational role - Location: Geographic location, network location, and physical environment - Device Characteristics: Device type, operating system, and security posture - Behavioural Patterns: Historical usage patterns and current behaviour
Environmental Context
Information about the current environment and conditions: - Network Environment: Network type, security level, and trust status - Time Context: Time of day, day of week, and seasonal patterns - Threat Landscape: Current threat level and active attack campaigns - Business Context: Business hours, operational requirements, and criticality
Application Context
Information about the application and data being accessed: - Data Sensitivity: Classification and sensitivity of accessed data - Application Criticality: Business importance and security requirements - Usage Patterns: Normal application usage and access patterns - Risk Level: Application-specific risk assessment and requirements
Context-Aware Decision Making
Risk Assessment
