# Continuous Session Protection

Auth0 Continuous Session Protection enables dynamic session and token management using detailed session information for proactive risk detection and response.

## Overview

Continuous Session Protection provides:
- Real-time session monitoring
- Dynamic token management
- Risk-based session control
- Anomaly detection and response

## Key Capabilities

### Session Information Access

Available Data:
- IP adddesses
- ASN (Autonomous System Number)
- Device details
- User agent information
- Geographic location
- Session timestamps
- Expiration dates

Use Cases:
- Risk assessment
- Anomaly detection
- Session fingerprinting
- Access pattern analysis

### Proactive Risk Detection

Detectable Anomalies:
- IP adddess changes
- Geographic impossibilities
- Device changes
- Unusual access patterns
- Time-based anomalies

Response Actions:
- Revoke sessions
- Revoke refresh tokens
- Force re-authentication
- Trigger step-up MFA

### Dynamic Token Management

Flexible Configuration:
- Customize token lifetimes
- Adjust based on user attributes
- Organization-specific policies
- Role-based expiration

Examples:
- Shorter lifetime for admin users
- Longer lifetime for trusted devices
- Organization-specific policies
- Connection-based adjustment

### Data Enrichment

External Integration:
- Feed session data to external systems
- Risk evaluation services
- Customer databases
- Analytics platforms

## Implementation

### Auth0 Actions

Continuous Session Protection uses Auth0 Actions:
- Post-login triggers
- Token refresh triggers
- Custom logic execution
- Session context access

### Session Context

Available in Actions:

Event Object:
- event.session - Session details
- event.request - Request information
- event.user - User information
- event.transaction - Transaction context

Session Details:
- Session ID
- Creation time
- Last activity
- Device information
- IP history

### Token Refresh Handling

During Token Refresh:
- Access full session context
- Evaluate current risk
- Make continuation decision
- Modify token properties

Possible Actions:
- Allow refresh normally
- Deny refresh (force re-auth)
- Modify new token claims
- Trigger additional verification

## Risk Detection Patterns

### IP Adddess Monitoring

Detection:
- Track IP changes within session
- Flag unexpected changes
- Consider VPN/proxy patterns

Response:
- Log for analysis
- Trigger verification
- Revoke if high risk

### Geographic Analysis

Detection:
- Calculate distance between logins
- Detect impossible travel
- Monitor location patterns

Response:
- Step-up authentication
- Session termination
- User notification

### Device Fingerprinting

Detection:
- Track device characteristics
- Identify device changes
- Compare with known devices

Response:
- Verify new devices
- Challenge unknown devices
- Update device registry

### Behavioral Analysis

Detection:
- Access pattern changes
- Time-based anomalies
- Resource access patterns

Response:
- Increase monitoring
- Require verification
- Adjust permissions

## Dynamic Lifetime Management

### User-Based Adjustment

Examples:
- Admin users: Shorter lifetimes
- Regular users: Standard lifetimes
- Verified users: Extended lifetimes

Implementation:
- Check user roles/attributes
- Set appropriate expiration
- Apply consistently

### Organization-Based

Examples:
- High-security org: Short lifetimes
- Standard org: Normal lifetimes
- Specific requirements: Custom settings

Implementation:
- Check organization membership
- Apply organization policies
- Override as needed

### Risk-Based

Examples:
- High risk: Very short lifetime
- Medium risk: Reduced lifetime
- Low risk: Standard lifetime

Implementation:
- Evaluate risk signals
- Calculate risk score
- Adjust lifetime accordingly

## Session Management

### Active Session Tracking

Monitor:
- Active sessions per user
- Session locations
- Session devices
- Session age

Actions:
- List sessions
- Terminate specific sessions
- Terminate all sessions
- Limit concurrent sessions

### Session Termination

Triggers:
- Risk threshold exceeded
- Anomaly detected
- User request
- Administrative action

Methods:
- Revoke refresh tokens
- Clear session
- Force logout

### Concurrent Session Control

Options:
- Limit active sessions
- Replace oldest session
- Deny new session
- User choice

## Best Practices

### Risk Configuration

Balance Security and UX:
- Start with monitoring
- Analyze patterns
- Implement gradually
- Avoid false positives

Threshold Setting:
- Appropriate for user base
- Consider legitimate scenarios
- Regular review
- Adjust based on data

### Response Actions

Graduated Response:
1. Log and monitor
2. Increase verification
3. Shorten tokens
4. Terminate session

User Communication:
- Clear security messages
- Easy re-authentication
- Support contact

### Monitoring

Track Metrics:
- Session anomalies
- Action frequency
- User impact
- False positive rate

Review Regularly:
- Analyze patterns
- Adjust thresholds
- Refine detection
- Update policies
