New Update

Information grows at a rapid pace and so do malicious attacks. Security has

therefore become the mission critical aspect of almost everything. Till now,

consolidation of resources in a data center has been seen as the main advantage

of virtualization. But now, the ability to isolate virtual machines running on a

physical machine has given opportunities for enhancing security at end points.

The Concept



Security vendor Symantec has come up with a new virtual machine technology

to protect Web surfers from online attacks. VIBES, stands for virtualization

based end point security, which works on the concept of three virtual machines

for a single user handling operations of different security levels. The software

does so by automatically recognizing the security level of different operations

and then seamlessly switching between different virtual machines in a way which

is transparent to both user and the website. The advantage being even in the

case of an attack, it prevents malware from permanently damaging a user machine

and at the same time protects sensitive information from theft.

Direct Hit!

How it works?



VIBES basically works in three operating modes. First being Playground which

is used for execution of suspicious active content. Second is the User mode

which takes care of day to day activities. And last but not the least is the

Trusted mode which is responsible for entering sensitive information, for

example, when it detects a SSL protocol for safe online transactions. By doing

so, it also improves browser security by enabling users to seamlessly use

different virtual execution environments to carry out different Web

transactions.

While accessing a Web site using https, the protocol for encrypting sensitive

data transactions, the VIBES system moves the operation again to a Trusted

Virtual Machine that provides a higher level of security. All other activities

are carried out in a mode that offers the level of security offered by the

antivirus and other security software installed on the computer. The isolation

of these activities are all invisible to the end user.

Switching between

the three virtual machines is transparent for both the user and the website.

Because Vibes works on virtual machines. Even if a user ends up accidentally

installing a malicious software on the PC, the virus can't access anything

important and also disappears when the virtual machine session is closed.

What lies ahead?



Being developed by Symantec Research Labs, VIBES might not make it to being

a full fledged product, but learnings from this prototype might be seen in other

future products. The current prototype supports Linux and VMware, but is wisely

capable of supporting other virtualization products and operating systems. Data

centers have already been witnessing the adoption of virtualization technology,

where it is being used to consolidate server applications onto fewer machines.

But now, companies like Symantec are looking at ways to use the technology on

the desktop as well as the data center, and in so-called cloud computing

platforms.
