HTTP Flood / Web DDoS
An HTTP flood is an application-layer denial-of-service pattern that overwhelms web resources with large volumes of seemingly valid requests.
Mechanism
Requests consume application, database, cache, or connection resources faster than the service can process them. Unlike a simple network flood, the traffic can resemble normal HTTP.
Indicators to watch
Sudden request-rate changes, endpoint concentration, high application latency, cache misses, elevated CPU/database load, and traffic patterns that differ from the normal client population.
Concept diagram
Defensive controls
Use CDN/WAF protection, caching, rate limits, bot management, autoscaling, request budgets, circuit breakers, and capacity planning.
Recommended security control
WAF / CDN rate limiting
Use load-test tools only against systems where you have explicit authorization.

The administrator has not attached a tool link yet. This slot will show “Build Soon” until an external link is configured.
Defence techniques
Defence techniques for this attack will be added by the administrator.
All attack descriptions are for defensive education. Test scanning, traffic generation, interception, wireless testing, and vulnerable applications only on systems and networks you own or are explicitly authorized to assess.
