BARE METAL ENVIRONMENT & HYPERVISORS

1.   I had till now been playing around with Virtual Machines for quiet some time . I started with loading xp on Vista around 2006-7 and then tried networking,played around with basic linux OS....but what I did everi time was that I loaded the host OS first and then allocated the desired resources in form of some RAM and HDD and then booting the new OS....but then I was wasting the host OS Resource that actually is running the various virtual machines on it.....so how to use that, is where Bare Metal Environment comes in to rescue.

2.    Simply told,a bare metal environment is a system in which a virtual machine is installed directly on hardware rather than within the host operating system (OS). The term "bare metal" refers to a hard disk, the usual medium on which a computer's OS is installed.But then how come it is called virtual when the machine is directly running on the hardware? So actually a kind of  a pseudonym since a virtual machine running directly on bare metal would technically not be a virtual machine. In such cases VMs run within a hypervisor which creates the abstraction layer between physical and virtual hardware. So whats Hypervisor?? :-)

3.    A hypervisor is actually the virtual machine manager (VMM), or a virtualization technique allowing multiple operating systems to run concurrently on a host computer. Multiple instances of a variety of operating systems may share the virtualized hardware resources.The hypervisors are classified into basically two types as follows :

Type 1 refers to bare metal hypervisors that run directly on the host's hardware to control the hardware and to manage guest operating systems. 

Type 2 refers to hypervisors that run within a conventional operating system environment. With the hypervisor layer as a distinct second software level, guest operating systems run at the third level above the hardware.This classification can be made more clear with the help of figures below :

FinFisher : THE LAWFUL INTERCEPTOR

1.  Some thing to read here about one security software named FINFISHER thats making some news...a sequence wise time line of events related to this is produced below : 

-  FinFisher is security software. 

-  Marketed by Gamma International to various government security officials assuring that it could be covertly installed on suspect's computers through exploiting security lapses.

-  In the name of Lawful Interception (LI), FinFisher was found in the Egyptian Secret Police Spy headquarters used to track people down during the revolution when Egyptian dissidents ransacked the office's of Egypt's secret police during the overthrow of President Hosni Mubarak 

-  Egyptian dissidents who ransacked the office discovered a contract with Gamma International for £287,000 for a license to run the FinFisher software.

-  A security flaw in so called "designed secure" applications like Apple's iTunes allowed unauthorized third parties to use iTunes online update procedures to install unauthorized programs.Gamma International offered presentations to government security officials at security software trade shows where they described to security officials how to covertly install the FinFisher spy software on suspect's computers using iTunes' update procedures.

FEATURES OF FINFISHER : 

-  FinFisher is able to record Skype and other voice over IP communications.

-  Logs keystrokes and turn on a computer's webcam and microphone. 

-  Can also steal files from a hard disk

-  Built to bypass dozens of antivirus systems.

-  Presently found across 12 C&C servers in 10 countries: the US, Indonesia, Australia, Qatar, Ethiopia, Czech Republic, Estonia, Mongolia, Latvia and Dubai.

-  Not confirmed by any govt agencies as being used officially but then who else would at such a large scale???

-  Expected to be particularly difficult to detect. 

-  Used to access target Systems to give full access to stored information with the ability to take control of target systems' functions to the point of capturing encrypted data and communications. 

"When used in combination with enhanced remote deployment methods, the Government Agencies will have the capability to remotely deploy software on target systems".............................extract from official finfisher site at http://www.finfisher.com/FinFisher/en/portfolio.php
