Rate limiting : DoS prevention
 
DoS prevention
You can protect your web assets from a wide variety of denial of service (DoS) attacks.
 
Some DoS protection features are not supported in all modes of operation. For details, see “Supported features in each operation mode”.
DoS features are organized by which open system interconnections (OSI) model layer they use primarily to apply the rate limit:
Application layer (HTTP or HTTPS)
Network and transport layer (TCP/IP)
Appropriate DoS rate limits vary by the web application you are protecting. For details, see “Reducing false positives”.
