That virtual security question

Introducting virtualisation to your workplace may be ideal, but you need to conisder the long term security risks.

There has been a rapid adoption of virtualisation technologies by businesses in recent times in order to decrease costs and improve efficiencies and availability of IT resources as well as conserve energy.  

As with all new technologies that become prolific throughout the IT industry in a short space of time, there is uncertainty around the security concerns of virtualised environments.  In most cases, deployment of virtualisation is considered more important than taking appropriate security measures, which can prove to be a risky move in the long term.

There seems to be a lack of consensus within the IT industry whether virtualised environments are fundamentally no less secure than physical ones, and that virtualisation can actually enable better security. The bottom line, however, is that virtualisation platforms are software and all software can have flaws. It is how we thoroughly plan and introduce proper policies and IT strategies to secure these platforms that will eventually mitigate the risk of attacks.

Why Virtualise?
 
Virtualisation makes it easy to build and deploy new releases and put changes into production. Service providers have also used virtualisation to respond to customer demands and provide capabilities such as instant provisioning, as well as the ability to offer the isolation and manageability of dedicated hosting without reserving expensive hardware for each customer. Today, these capabilities are prerequisites to achieving the elasticity and flexibility of private and public clouds.

The ‘Big’ question of what’s in it for me?

Virtualised platforms have the potential to significantly lower IT costs by moving to a virtualised infrastructure. According to a CIO Research Survey, the top five reasons customers move to virtual servers for their applications are:
