Virtualisation vendor VMware has quietly begun sharing some of its software secrets with the IT security industry under an unannounced plan to create better ways of securing virtual machines.
You've only got to hang around a datacentre for about 30 seconds before someone starts raving on about virtualisation. While the cost benefits of virtualisation are obvious, the management challenges often get swept under the carpet.

SCVMM 2008 R2 is a very competent product, neatly bringing Microsoft's virtualisation management offering in line with the competition at the same time as offering management of disparate platforms in the one product.
