An Anomaly is something that differs from the expected norm. In software and systems:
Types of Anomaly:
- Data anomalies: Unusual patterns in information
- Behaviour anomalies: Unexpected system actions
- Performance anomalies: Unusual speed or resource use
Detection Methods:
- Statistical analysis: Compare to historical data
- Machine learning: Identify patterns that don’t fit
- Rule-based systems: Check against predefined norms
Importance:
- Security: Can indicate potential threats
- Quality assurance: Help find bugs or issues
- Performance optimisation: Highlight areas for improvement
Handling Anomalies:
- Investigation: Determine the cause
- Mitigation: Address the underlying issue
- Monitoring: Watch for recurrence
Anomalies often require prompt attention to maintain system health and security.
