Discussion

A web server can limit the ability of the web server being used in a DoS attack through several methods. The methods employed will depend upon the hosted applications and their resource needs for proper operation. An example setting that could be used to limit the ability of the web server being used in a DoS attack is bandwidth throttling.

Check Content

1. Open $DOMAIN_HOME/config/fmwconfig/components/OHS/<componentName>/httpd.conf and every .conf file (e.g., ssl.conf) included in it with an editor.

2. Search for the "LimitInternalRecursion" directive at the server, virtual host, and directory configuration scopes.

3. If the "LimitInternalRecursion" directive is omitted or is set greater than 55, this is a finding.

Fix Text

1. Open $DOMAIN_HOME/config/fmwconfig/components/OHS/<componentName>/httpd.conf and every .conf file (e.g., ssl.conf) included in it with an editor.

2. Search for the "LimitInternalRecursion" directive at the server and virtual host configuration scopes.

3. Set the "LimitInternalRecursion" directive to "55", add the directive if it does not exist.
