This white paper discusses an integrated security solution from Juniper Networks for virtualized data centers and clouds. It addresses the security challenges introduced by virtualized workloads, which physical firewalls have limited visibility into. The solution includes Juniper's SRX firewalls to protect physical workloads and segment traffic, and Firefly Host virtual firewalls to protect virtualized workloads within hypervisors and enforce the same security policies. This provides consistent security across physical and virtual environments as organizations adopt cloud computing.
