cyberstrikeus Ensure the KeepAliveTimeout Is Set Properly
Description
The KeepAliveTimeout directive specifies the number of seconds Apache will wait for a subsequent request before closing a connection that is being kept alive.
Rationale
Reducing the number of seconds that Apache HTTP server will keep unused resources allocated will increase the availability of resources to serve other requests. This efficiency gain may improve a server's resiliency to DoS attacks.
Impact
None documented
Audit Procedure
