Discussion

Limiting the total number of connections that a server is allowed to open prevents an attacker from overloading a web server. Overloading the server will prevent it from managing other tasks besides serving web requests. This setting works together with per-client limits to mitigate against DDoS attacks.

Check Content

At the command line execute the following command:
 
grep maxconn /etc/haproxy/haproxy.cfg
 
If the "maxconn" value is not set to "32768", this is a finding.

Fix Text

Navigate to and open /etc/haproxy/haproxy.cfg

Navigate to the "globals" section and add the following line:

maxconn 32768
