Barrier1 has Virtualized Network Security

Barrier1 has brought Virtualization to Network Security. Virtualization is designed to be helpful in making more efficient use of underutilized hardware and yet keeping networks isolated from one another.. The classic case involves a rack of servers each using a fraction of their resources. Once a virtual network is attached to a physical network adapter, it is exposed to the same security risks as that physical network adapter. Virtual machines cannot intercept network packets from the host operating system. Similarly, the host operating system cannot intercept network packets from a virtual machine. This isolation is enforced by the virtual machine network services driver, which determines whether a network packet is routed to the host operating system or to a virtual machine.

Barrier1 Network Security Virtualization brings individual VM protection as well as inter-VM protection. To truly mitigate the risks within the virtual environment, especially those related to inter-VM communication, individual inspection of all 7 OSI layers in near real time is required. Barrier1, along with its “AARE Engine” has an architecture that delivers effective multi-layered defense and self-protection.on a per VPM basis. By enforcing policies at the VM level, integrating network security protection elements that inspect and have knowledge of all aspects of the 7 OSI layers is key to the overall security architecture within VM.

• VM Enforcement of policies and integrating all network security point solutions such as Firewall, IDS, Anti-Spam, Anti Virus, Web Application Firewall, provides granular visibility and control of individual VM as well as inter-VM and network traffic. Enforcing individual or group VM policies stops inter-VM malware propagation more effectively than one-size-fits-all rule bases. Default policies are automatically applied to every new VM, mitigating the risks of VM sprawl.

• Guaranteed VM Isolation between and within trust levels (e.g., production, QA) makes vitalizing mission critical systems and customer data viable. This further boosts the ratio of VMs to host servers, giving enterprises a greater return on their virtualization investments.

• Migrations are achieved by continuous inspection of all network security tools in production as VMs automatically move from host to host.

• Barrier1 monitors & stores all network connections. Thus giving Barrier1 the ability to block attacks and other unauthorized connection attempts from VMs.
