As security pros wait for more details about the VMware ESX hypervisor source code leak, should they be panicking?

Well no, not yet, anyway. Without knowing exactly what source code was leaked, it’s hard to know the extent of the threat, security experts have said. However, the answer may come soon — there are rumors that hackers will release more source code on Saturday.

Until then, virtualization security experts are offering some advice for enterprises running ESX. As with most things in security, much of the advice has to do with simply following best practices. However, virtualization security best practices may not always be at the top of an organization’s to-do list; the code leak should provide some prodding.

First off, organizations should block all Internet access to the hypervisor platform — especially to the Service Console — which is something they should already be doing, according to Dave Shackleford, principal consultant at Voodoo Security and senior vice president of research and CTO at IANS. They should also make sure all VMs are patched and restrict any copy/paste or other functionality between the VM and ESX host, he said in an email. (On the patching front, organizations using ESX should pay attention to last week’s security bulletin from VMware about an update
