PacketMotion, a company focusing on User Activity Management and Network Visibility, announced the availability of its VM-to-VM traffic monitoring solution, PacketSentry Virtual Probe.
The lack of visibility on VM-to-VM traffic is a key issue when considering the security of virtual machines: it makes impossible or extremely difficult to actually monitor very relevant network traffic, and to correctly satisfy some requirements for security compliance or internal audit. The “black hole” of VM-to-VM has been pointed out multiple times, and various vendors gave different answers to this issue.
PacketSentry Virtual Probe has been implemented as a guest VM sitting on the virtual network and connected to promiscuos mode ports on the virtual switch. It will then monitor and secure traffic on VMware clusters leveraging the extensive PacketSentry database: such systems should always be managed by the network and security teams rather than the virtualization administrators, ensuring segregation of duties and allowing security management to be executed by the people in charge of it.
