We will be looking on a number of scenarios typically done by adversaries, e.g.

QS_SrvMinDataRate - This setting requires a minimum of 150 bytes per second per connection, and limits the connection to 1200 bytes per second when the server reaches the MaxClients limit. In this article, we will be looking on Wireshark display filters and see how we could detect various network attacks with them in Wireshark.QS_SrvMaxConnClose - This setting disables the KeepAlive function when at least 180 connections exist.QS_SrvMaxConnPerIP - This setting limits each IP address to a maximum number of 50 connections.In Proceedings of the 39th Hawaii International Conference on. Design and implementation of a multi-use attack-defend computer security lab. P., Melton, S., Manz, D., King, K., Oman, P. QS_ClientEntries - This setting tracks up to 100,000 connections. Hands-on denial of service lab exercises using SlowLoris and RUDY.

MaxClients - This setting limits the maximum number of connections to 256.

This example configuration will enforce the following behavior: slowloris keeping connections open without requesting anything): QS_SrvMinDataRate 150 1200 # and limit request header and body ( careful, that limits uploads and post requests too): # LimitRequestFields 30 # QS_LimitRequestBody 102400 # handles connections from up to 100000 different IPs QS_ClientEntries 100000 # will allow only 50 connections per IP QS_SrvMaxConnPerIP 50 # maximum number of active TCP connections is limited to 256 MaxClients 256 # disables keep - alive when 70 % of the TCP connections are occupied: QS_SrvMaxConnClose 180 # minimum request / response speed ( deny slow clients blocking the server, ie.
