OH12-1X-000307 - OHS must be tuned to handle the operational requirements of the hosted application.

Information

A Denial of Service (DoS) can occur when the web server is so overwhelmed that it can no longer respond to additional requests. A web server not properly tuned may become overwhelmed and cause a DoS condition even with expected traffic from users. To avoid a DoS, the web server must be tuned to handle the expected traffic for the hosted applications.

NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.

Solution

Set the following directives appropriately for the server and application:
MaxClients
MPM Module
-worker (StartServers, MinSpareThreads, MaxSpareThreads, ThreadsPerChild)
Timeout
KeepAlive
KeepAliveTimeout
MaxKeepAliveRequests
ListenBacklog
LimitRequestBody
LimitRequestFields
LimitRequestFieldSize
LimitRequestLine
LimitXMLRequestBody
LimitInternalRecursion
