Discussion

Log records can be generated from various components within the web server (e.g., httpd, plug-ins to external backends, etc.). From a web server perspective, certain specific web server functionalities may be logged as well. The web server must allow the definition of what events are to be logged. As conditions change, the number and types of events to be logged may change, and the web server must be able to facilitate these changes. As a Tomcat derivative, tc Server can be configured with an “AccessLogValve”. A Valve element represents a component that can be inserted into the request processing pipeline. The pattern attribute of the “AccessLogValve” controls which data gets logged.

Check Content

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

Navigate to the <Host> node.
 
Verify that the node contains a <Valve className="org.apache.catalina.valves.AccessLogValve"> node.

If an “AccessLogValve” is not configured correctly or is missing, this is a finding.

Note: The “AccessLogValve” should be configured as follows:

                <Valve className="org.apache.catalina.valves.AccessLogValve"
                       directory="logs"
                       pattern="%h %l %u %t "%r" %s %b"
                       prefix="localhost_access_log."
                       suffix=".txt"/>
