Discussion

Denial of Service is one threat against web servers. Many DoS attacks attempt to consume web server resources in such a way that no more resources are available to satisfy legitimate requests. Mitigation against these threats is to take steps to limit the number of resources that can be consumed in certain ways. tc Server provides the “connectionTimeout” attribute. This sets the number of milliseconds tc Server will wait, after accepting a connection, for the request URI line to be presented. This timeout will also be used when reading the request body (if any).

Check Content

Navigate to and open /usr/lib/vmware-vcops/tomcat-enterprise/conf/server.xml.

Navigate to each of the <Connector> nodes.

If the value of “connectionTimeout” is not set to “20000” or is missing, this is a finding.

Fix Text

Navigate to and open /usr/lib/vmware-vcops/tomcat-enterprise/conf/server.xml.

Navigate to each of the <Connector> nodes.

Configure each <Connector> with the value 'connectionTimeout="20000"'.
