Sourcefire’s Sourcefire 3D System will deliver full intrusion-protection blocking capability for both the VMware-based and Xen-based virtual machine platforms. At present, it’s limited to intrusion-detection monitoring and alerting. Sourcefire is turning its attention to Xen because “it’s open source, and Xen is being adopted by some cloud providers” Sourcefire anticipates having blocking capability by year-end for both virtualization platforms by 2013-2014. It’s making progress in adapting the full strength of its traditional IPS to a virtualized environment.”]
