Question
A company is experiencing a web services outage on the public network. The services are up and available but inaccessible. The network logs show a sudden increase in network traffic that is causing the outage. Which of the following attacks is the organization experiencing?
Options
- AARP poisoning
- BBrute force
- CBuffer overflow
- DDDoS
Explanation
DDoS (Distributed Denial of Service) matches all the indicators: services are up but inaccessible, and logs show a sudden traffic surge - the attacker is overwhelming the network with requests from multiple sources until legitimate users can't get through.
Why the distractors are wrong:
- A. ARP poisoning manipulates local network address resolution to redirect traffic; it doesn't cause a traffic flood and targets internal networks, not public service availability.
- B. Brute force involves repeated credential guessing attempts; it wouldn't generate the kind of broad network traffic spike described here.
- C. Buffer overflow exploits memory handling in a specific application to crash it or execute code; the service would typically go down, not remain up-but-unreachable under a traffic flood.
Memory tip: Think of DDoS as a "traffic jam attack" - the road (network) still exists, the destination (server) is fine, but so many cars (requests) flood in that no legitimate driver can get through. Whenever you see "services up but inaccessible + sudden traffic spike," that combination is the DDoS fingerprint.
