As technology continues to advance, it's important to stay informed about new techniques that can help your organization remain competitive. 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.Companies often look for ways technology can help them decrease costs and improve efficiencies. 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 allows administrators to provision and scale firewall protection to meet the needs of virtualized and cloud environments. 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.
All this enables the host to contain one or more Virtual Machines (or partitions) and share physical resources with them. Enterprises and service providers can leverage their virtualization investment to create a granular security perimeter, giving dedicated security resources within a cloud construct to tenants and service subscribers.Ī 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). It provides dedicated security services and assured traffic isolation within the cloud, along with customizable firewall controls as an additional managed service. Security virtualization acts as a barrier to secure perimeter access to a network.
What Can You Do with Security Virtualization? Many organizations do not realize that using their existing legacy security solutions can expose them to these types of attacks and data loss. Other security threats include unauthorized access, denial of service, and exploits. For intrusion prevention systems (IPS), malware targeted for physical and virtual machines causes infection via the virtual network.Multiple servers are consolidated which increases the risk that a compromise may spread from applications on the same host.Isolation between components such as guest OSs and applications, hypervisors, hardware are weakened.File sharing between hosts and guests is not secure.However, virtualization also introduces security challenges that physical security systems cannot adequately protect against: Virtualization centralizes administrative tasks while improving scalability and workloads, and leads to the consolidation of network infrastructure, lower OPEX, and ease of management. Problems Security Virtualization Addresses Security virtualization is the process, procedure and policy that ensures that the virtualized hardware infrastructure is secure and protected. Virtualization is the process of running multiple virtual instances of a device on a single physical hardware resource.
