Ktraq IDS is my latest security invention, and I feel it is the cleanest solution to date, for absolving systemcall hijacking.
Ktraq is by far, the most reliable and efficient way to detect, and disable kernel rootkits in Linux. As mentioned in the detailed
introduction and example presented here: http://www.bitlackeys.com/projects/ktraq

Arguably, one of the most complex and lethal types of malicious code today is the "rootkit." As its name implies, this type of malware can gain "root" access, the highest privilege level in Unix systems, as well as deploy its "kit" of small, often malicious, executable packages. The code can provide continual and undetectable access into a machine.

Today's rootkits draw their power from having access to the kernel of the operating system. These "kernel-mode" rootkits run at the same lower level as all other trusted system processes, thus granting system control and providing effective ways to remain hidden.

Torbutton is a 1-click way for Firefox users to enable or disable the browser's use of Tor. It adds a panel to the statusbar that says "Tor Enabled" (in green) or "Tor Disabled" (in red). The user may click on the panel to toggle the status. If the user (or some other extension) changes the proxy settings, the change is automatically reflected in the statusbar.

Recently the government has been infringing on our rights and privacy online globally. This doesnt just effect the United States, the NSA in the United States is and has been logging more than 50% of all internet communications. And most likely All smtp/pop/imap and webmail is probably logged and filtered for certain keywords.
I take Privacy & The freedoms we had and are now loosing seriously.
