Overview
What is TCP/IP Stack Hardener?
TCP/IP Stack Hardener : A straightforward application that attempts to mitigate a type of denial of service attack by tweaking some parameters of the TCP/IP stack
In depth
A closer look at TCP/IP Stack Hardener
TCP/IP Stack Hardener has been designed as an experimental tool that should offer some sort of protection against SYN flood attacks, which is a form of denial-of-service involving the transmission of SYN requests to the target until all its resources are used and it becomes unresponsive. What this tool attempts to accomplish is modify some settings for the TCP/IP stack in order to be able to face this type of attacks. It is not foolproof but the tweaks should make the system resist a little longer as the aim is to restrict the size of the half-open connections queue, cause a SYN flood attack creates a large number of such connections.
