Discussion

Web server management includes the ability to control the number of users and user sessions that utilize a web server. Limiting the number of allowed users and sessions per user is helpful in limiting risks related to several types of Denial of Service attacks. Although there is some latitude concerning the settings themselves, the settings should follow DoD-recommended values, but the settings should be configurable to allow for future DoD direction. While the DoD will specify recommended values, the values can be adjusted to accommodate the operational requirement of a given system.

Check Content

1. Open $DOMAIN_HOME/config/fmwconfig/components/OHS/<componentName>/ohs.plugins.nodemanager.properties file with an editor.

2. Search for the "mpm" property.

3. If the "mpm" property is omitted or commented out, this is a finding.

4. If the "mpm" property is not set to "worker", this is a finding.

Fix Text

1. Open $DOMAIN_HOME/config/fmwconfig/components/OHS/<componentName>/ohs.plugins.nodemanager.properties with an editor.

2. Set the "mpm" property to a value of "worker", add the property if it does not exist.
