VCLD-67-000001 - VAMI must limit the number of simultaneous requests.

Information

Denial of service (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.

Solution

Navigate to and open /opt/vmware/etc/lighttpd/lighttpd.conf.

Add or reconfigure the following value:

server.max-connections = 1024
