How Does Security Virtualization Work?
A virtualization system consists of a host operating system, a hypervisor, and a guest operating system. The host is the underlying hardware of the virtualization system that provides computing resources (physical interface cards, CPUs, memory, management ports, operating system, third-party software, hypervisor). All this enables the host to contain one or more Virtual Machines (or partitions) and share physical resources with them.
Juniper Networks Implementation
The vSRX Services Gateway is a stateful firewall that integrates with a hypervisor at the kernel and inspects and secures traffic at the virtual layer. The vSRX allows administrators to provision and scale firewall protection to meet the needs of virtualized and cloud environments.
The vSRX brings the Junos operating system to x86-based virtualization environments, and includes network firewall, IPS, and VPN technologies, next-generation firewall technologies that include Layer 7 application control, availability, traffic flow optimization, web filtering, antivirus, anti-spam, and network access control enforcement. The vSRX can be used in the same way as a physical appliance and supports the Juniper Networks Contrail product, OpenContrail, Network Functions Virtualization (NFV) use cases, and third-party SDN solutions.
