Everything new is old again – Native Client
Google has garnered a lot of interest, over the past day or two, with its radically new idea, released under the name Native Client. You can read the announcement at http://google-code-updates.blogspot.com/2008/12/native-client-technology-for-running.html or download the research paper (in PDF) at http://nativeclient.googlecode.com/svn/trunk/nacl/googleclient/native_client/documentation/nacl_paper.pdf
That idea sounded so familiar I just knew it had to have been done before.
It has. It’s just a dressed up version of an activity monitor. The oldest form of AV actually implemented. In fact, it dates back to the days just slightly before the first PC viruses, when people were trying to prevent damage by some of the early PC trojans that were being shared on BBSes.
Or, if they take it far enough, and if you like, you can call it a form of virtual machine. And we are back to http://blogs.securiteam.com/index.php/archives/1171
