Since this is very sensitive data, this segment should be on distinct virtual switches when possible, with multiple dedicated physical NICs for redundancy, as well. For example, VMware's default virtual switch can be placed into promiscuous mode for monitoring, and can also have rudimentary MAC address filtering enabled to prevent MAC spoofing attacks. The fluid nature of virtualized infrastructure and the high mobility of virtual machines (VMs) are what make virtualization and the Cloud valuable. Do Not Sell My Personal Info. This is one area in the cloud security shared responsibility model where customer tenants are responsible for security. By scanning local subnets and capturing MAC addresses and comparing them to these OUIs, security teams can correlate this data with other inventory information. Kali virtual machine ready to boot.

True SPAN or mirror ports cannot be created for dedicated traffic mirroring, extensive port-level security is not available (locking down one port to one MAC address, for example), and management capabilities are very limited. This is likely due to the fact that vm’s have reached maturity in their deployment and the attack surfaces are fairly well understood. One of the most commonly overlooked elements of virtualization security is proper management and administration of hypervisor platforms and related components. management for these systems increases. The second major area to consider in properly securing a virtual environment is operations management, namely change and configuration management. For more information about virus protection, distributed by MIT at no cost. Although its not possible to cover everything in a single post. One of the things that our Detection and Response Team (DART) and Customer Service and Support (CSS) security teams see frequently during investigation of customer incidents are attacks on virtual machines from the internet.
