VAMI must limit the number of simultaneous requests.
At Note: The below command must be run from a bash shell and not from a shell generated by the "appliance shell". Use the "chsh" command to change the shell for the account to "/bin/bash". At the command prompt, execute the following command: # grep "server.max-connections = 1024" /opt/vmware/etc/lighttpd/lighttpd.conf Expected result: server.max-connections = 1024 If the output does not match the expected result, this is a finding.
Denial of service (DOS) (DoS) 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. VAMI provides the "maxConnections" attribute of the <Connector Elements> to limit the number of concurrent TCP connections. This comes preconfigured with a tested, supported value that must be verified and maintained.
Navigate to and open /opt/vmware/etc/lighttpd/lighttpd.conf. Add or reconfigure the following value: server.max-connections = 1024
