My Institute uses Proxy Authentication for monitoring individual browsing activities. This usually means I need to enter my username and password for using any internet related things.
But recently I was using a virtual machine (Ubuntu on VMware) on my windows 7 and noted that I can browse inside the virtual machine without entering any password. I tested it again and again using a clean system to avoid the chance of password caching or saving.
How can this be possible ? I remember that the virtual network device is configured to use NAT. Even then this shouldn't be possible ryt?
What is happening behind? How can the authentication be strengthened to take care of such loop holes?
