InformationLimit access to the web administration application to only those with a justified need.
Limiting access to the least privilege will ensure only those people with a justified need will have access to a resource. The web administration application should be limited to only administrators.
SolutionFor the administration application, edit $CATALINA_HOME/conf/server.xml and uncomment the following:
<Valve className='org.apache.catalina.valves.RemoteAddrValve' allow='127.0.0.1'/>
Note: The RemoteAddrValve property expects a regular expression, therefore periods and other regular expression meta-characters must be escaped.
By default, this configuration is not present.
