Structure:
- Network of infected devices (bots)
- Central command and control server
Creation:
- Malware infection
- Exploitation of vulnerabilities
Uses:
- Distributed Denial of Service (DDoS) attacks
- Spam distribution
- Data theft
Detection:
- Network traffic analysis
- Behavioural anomaly detection
Prevention:
- Regular software updates
- Strong security measures
- User education
