Juniper is updating its vGW Virtual Gateway platform with security management, continuous monitoring and antivirus features specifically designed for virtual environments.
Networks has rolled out antivirus and other security measures specifically to
protect virtual machines in its virtual gateway platform.
The new vGW
Virtual Gateway offers virtualization-specific antivirus protections and
continuous monitoring against malware and external intruders. Juniper, which
made the announcement Aug. 29 at the start of the VMworld conference in Las
Vegas, is planning to offer the security updates early in the fourth quarter of
are concerned about the impact having scanning and monitoring technologies,
such as antivirus products, will have on the performance of each individual
virtual machine within the physical server. Multiple antivirus scans happening
at the same time can consume the server's resources and slow down its
responsiveness, affecting all the other VMs hosted on the server.

that the new security and
monitoring features the company offers do not "impede" virtualized
line, it's all about performance," Konstantas said.
Gateway is based on technology that Juniper acquired as part of its purchase of
Altor Networks in December 2010. At the RSA Security conference in February,
Juniper made the first update to the new platform with version 4.5 to bring it
in line with the rest of the Juniper portfolio.

Konstantas said. The antivirus scans virtual machines for resident malware and
other programs designed to hide inside files, and it quarantines the infected
files or the whole VM as necessary after detecting malware. Administrators can
choose to run scans on-demand during off-peak hours or when the virtual servers
are offline. They can also use the on-access option, which deploys an agent to
scan the files.
errors make the systems vulnerable to compromise in the first place. The vGW
manages security in virtual machine environments by continuously monitoring for
changes within the VM's disk images to ensure security policies are not being
violated, Konstantas said. The vGW 5.0 also integrates with Juniper's SRX
security appliances to monitor VM security configurations.
that most security and compliance issues within an organization are the result
of systems being configured incorrectly, incorporating configuration management
was a natural step for Juniper, Konstantas said.
The new vGW
Virtual Gateway works more like a universal threat management system designed
for the virtual environment. It provides integrated firewall protection,
intrusion detection, compliance monitoring and security management along with
antivirus protection, Konstantas said.
check for configuration changes on physical servers won't work for virtual
environments, Konstantas said. Organizations need a layer of dedicated security
management software for virtual machines to ensure all the security and
configuration issues are resolved immediately.
charges $700 per CPU on the physical host, Konstantas said. It doesn't matter
how few or how many virtual machines are hosted on the server as the pricing
would remain the same. This would help organizations scale up without suddenly
seeing their security costs jump, he said.
