I am working under advisory of Prof. Carl Gunter, in the Illinois Security Lab. My broad research area is Information Security.
 
I have a big interest in malware detection and prevention, anti spam, and browser security. I believe those are the issues that all computer users (including non-techinal ones) care about the most. I am also interested in applications of virtualization technology in Security.
 
In this section you will find resources from my projects, as well as my comments on other people's research projects related to mine
 
For information about my current and past projects, please check out my CV here.

Above the clouds - An introduction to cloud computing

The cloud

Cloud computing is a new and emerging area, so new that each person can have his own definition of what "cloud computing" is. 

In their paper Above the Clouds: A Berkeley View of Cloud Computing a group from Berkeley explains their definition, and discusses the benefits as well as the challenges that cloud computing brings. 

You can find my slide set for this topic here: Cloud Computing Infrastructure - ppt, pptx

Beside discussing the mentioned above paper, I also include a brief description of Amazon EC2 and Google AppEngine, two of the biggest cloud providers currently in the market.

This is some interesting research from the folks at Princeton in which they show that DRAM retains data after the computer has been powered off. Taking advantage of this, and the fact that disk encryption key is stored in memory, they can plugin a usb drive while your computer is on (even in locked or sleep mode), boot their OS stored in the usb drive, dump your memory, and steal your disk encryption key which resides on DRAM. 

This attack is hard to defend in the sense that it takes advantage of a physical characteristic of DRAM: the content is not erased immediately after the memory chip  is powered off. You can not rely on the OS to do the erasing job because the attacker can turn off the machine by unplugging power cable. Also, the disk encryption key must reside in memory in order to be used.

The best defense mechanism that I can think of now is to store disk encryption key in a memory location which will be erased right after the machine is booted up... some location that will be used temporary by BIOS for example.
