Security: VMware wrote a VMsafe paper back in 2002, says a blogger

Excerpt:

n this paper we present a new architecture for building intrusion detection systems that provides good visibility into the state of the monitored host, while still providing strong isolation for the IDS, thus lending significant resistance to both evasion and attack.

Our approach leverages virtual machine monitor (VMM) technology. This mechanism allows us to pull our IDS “outside” of the host it is monitoring, into a completely different hardware protection domain, providing a high-confidence barrier between the IDS and an attacker’s malicious code.

We achieve this through the use of a virtual machine monitor. Using this approach allows us to isolate the IDS from the monitored host but still retain excellent visibility into the host’s state. The VMM also offers us the unique ability to completely mediate interactions between the host software and the underlying hardware. We present a detailed study of our architecture, including Livewire, a prototype implementation. We demonstrate Livewire by implementing a suite of simple intrusion detection policies and using them to detect real attacks.

Also a good friend of mine is looking for some ideas and wondering if the whole virtsec thing is a hype or a load of crap. Expect a discussion/article soon.

Redhot Future Of IT Part I :Marketing yourself as IT professional

I had promised about the "RedHot IT Future Series" and so we discuss here how you should market yourself EFFECTIVELY as an IT professional in this new (and dangerous) web age! Web is the place where you're a hero today and villain tomorrow. While there are lots of professionals who are active on the web, not all are enjoying a good reputation as they got "personal" with others and got into a cockfight. The passive IT professional has nothing to lose but nothing to gain at all!

I know "marketing" might seem as a greasy term but the idea is to have the truth about you out there. You know you're a good person and your family knows that you're really smart person but the rest of the world doesn't!

So the question is how do I market myself on the web as a true "nouveau IT professional". A guy who companies will be tempted to pick up the phone as say "Hey, we wanna talk with you. Can you fly over to Palo Alto (or Guatemala or Johan…
