What if you could enqueue from kernel space to user space all your incoming and outgoing network connections? Maybe you could develop some offensive/defensive applications to modify headers and payloads in real time, to detect unauthorized traffic like dns tunneling connections or to fool some well known network tools. This will be showed in Linux-powered devices. It will be explained too some remote OS fingerprinting techniques, both active and passive, implemented in tools like nmap, p0f, or vendor appliances, and a how to defeat them. This technique doesn't need virtual machines or kernel patches, and is highly portable to other platforms.
