TMA-NGINX-2.4.4
Ensure send_timeout is set to 10 seconds or less, but not 0
MediaNivel 1Automatizadanginx
Descripción
The send_timeout directive sets a timeout for transmitting a response to the client between two successive write operations. Every send_timeout must be between 1 and 10 seconds and the directive must be set (default 60s). Evaluated on the merged configuration printed by `nginx -T` (all included files; needs permission to read them). CIS marks this recommendation Manual; the automated check implements its audit procedure.
