A large media-streaming company receives complaints that its web application is timing out or failing...

The Certified Ethical Hacker (CEH) Web Application Hacking and DoS/DDoS module identifies Slowloris as an application-layer denial-of-service attack that targets web servers by maintaining a large number of half-open HTTP connections.

Slowloris works by sending partial HTTP requests very slowly, preventing the server from closing the connections. CEH documentation highlights that this attack does not rely on high bandwidth, making it difficult to detect using traditional network-based defenses.

Option C accurately matches the described symptoms and CEH’s definition.

Options A and B are network-layer flooding attacks, which were explicitly ruled out.

Option D is a packet fragmentation attack, not an application-layer DoS technique.

CEH stresses tuning connection timeouts and using reverse proxies as mitigations.
