Behavioral Analysis

Cert-IX Behavioral Analysis monitors user and system activities to establish baselines, detect anomalies, and identify potential security threats.

How Behavioral Analysis Works​

Baseline Establishment​

The system learns normal behavior patterns:

  • User login times and locations
  • Typical data access patterns
  • Application usage habits
  • Network communication patterns
  • System resource usage

Continuous Monitoring​

Real-time tracking of:

  • All user activities
  • System operations
  • Network communications
  • Data access events
  • Application behaviors

Anomaly Detection​

Identification of deviations from normal:

  • Statistical analysis
  • Machine learning models
  • Rule-based detection
  • Correlation analysis

Behavioral Indicators​

User Behavior Indicators​

Access Patterns​

  • Login time anomalies
  • Geographic impossibilities
  • Unusual resource access
  • Privilege escalation attempts
  • After-hours activity

Data Handling​

  • Bulk data access
  • Sensitive file access
  • Unusual downloads
  • External transfers
  • Print activities

Communication Patterns​

  • Email anomalies
  • External communications
  • New contact patterns
  • Messaging behavior

System Behavior Indicators​

Process Behavior​

  • Unusual process execution
  • Memory usage anomalies
  • CPU utilization spikes
  • New processes
  • Process chains

Network Behavior​

  • Traffic volume changes
  • New connections
  • Protocol anomalies
  • Bandwidth spikes
  • External communication

File System Behavior​

  • File creation patterns
  • Modification activity
  • Deletion patterns
  • Permission changes
  • Encryption activities

Using Behavioral Analysis​

Viewing Analysis​

  1. Navigate to Analytics → Behavioral Analysis
  2. View the behavioral dashboard
  3. Select analysis type (user/system)
  4. Review findings and alerts

User Analysis View​

  • User risk scores
  • Activity timelines
  • Behavior comparisons
  • Alert history
  • Investigation tools

System Analysis View​

  • System health indicators
  • Process monitoring
  • Network analysis
  • Resource usage
  • Anomaly detection

Investigation Tools​

User Investigation​

  1. Select user for investigation
  2. View activity timeline
  3. Compare to baseline
  4. Review related events
  5. Document findings

System Investigation​

  1. Select system/asset
  2. View behavior history
  3. Analyze anomalies
  4. Correlate events
  5. Identify root cause

Risk Scoring​

User Risk Score​

Calculated from:

  • Anomaly frequency
  • Anomaly severity
  • Access patterns
  • Historical behavior
  • Role-based factors

Score Interpretation​

ScoreRisk LevelAction
0-30LowNormal monitoring
31-60MediumEnhanced monitoring
61-80HighInvestigation recommended
81-100CriticalImmediate action required

Alerts and Notifications​

Alert Types​

  • Anomaly detection alerts
  • Threshold breach alerts
  • Pattern match alerts
  • Correlation alerts

Alert Configuration​

  • Sensitivity settings
  • Threshold values
  • Notification channels
  • Escalation rules

Privacy Considerations​

Data Protection​

  • Role-based access to behavioral data
  • Audit logging of analysis activities
  • Data retention policies
  • Anonymization options

Compliance​

  • GDPR considerations
  • Privacy regulations
  • Employee notification
  • Data minimization

Best Practices​

  1. Allow learning time - Baselines need data to establish
  2. Review regularly - Check behavioral insights frequently
  3. Investigate promptly - Act on high-risk indicators
  4. Update baselines - Reflect legitimate changes
  5. Balance privacy - Respect user privacy while maintaining security
  6. Document investigations - Keep records of analysis
