- Creating distractions
- Impacts network availability by overwhelming servers with traffic
DDoS - Distributed Denial of Service
- DoS but with many sources attacking a target
- Harder to mitage & more effective but requires more resources
Amplified DDoS Attacks
- Leverage servers or systems that generate a larger response to
- Commonly exploited protocols for amplification include
Reflected DDoS Attacks
- Exploits servers or systems to reflect attack traffic owards the target
- Attacks send requests with spoofed source IP addresses to these servers, making it appear as if the target is the source of the requests
- The servers then respond to the target with amplified traffic,
reflecting the attack back to the intended victim
DDoS Attacks and Targets

- Application DDoS
- Targets specific applications
- Operational technology (OT) DDoS
