Unisys has released an updated version of its Stealth microsegmentation security software. Stealth is designed to manage information security in hybrid cloud environments and on extended cloud networks.
Stealth is in broad use at all levels of government for its capability with hybrid cloud networks. According to Tom Patterson, Unisys’ Chief Trust Officer, the company plans to continue adding to the software’s capability in response to increasingly sophisticated cyber threats. “There is an absurdly high level of people not encrypting information and that leaves these extended networks open to adversaries,” Patterson says in an interview with CivSource. “Microsegmentation is designed to protect assets in the cloud and as information moves through extended networks like mobile or IoT devices. The other key thing to understand about microsegmentation, is that it’s another layer of software. There are no VPNs or on-premise hardware to maintain, which makes it readily adaptable for government computing environments.”
Stealth provides security teams with total visibility into cloud networks in order to protect critical assets and monitor for network intruders. The Stealth security portfolio, which includes Stealth(identity) for biometrics-based identity access management, relies on microsegmentation to protect information at the packet level. The goal of microsegmentation is to limit the ability of malware to be able to target critical information or move within a system looking for high-value information.
The new version of Stealth also introduces adaptive protection with the ability to isolate users at the first sign of compromise.
This year, Gartner identified microsegmentation as one of its “top technologies for information security in 2017,” noting that “microsegmentation has been used to describe mostly the east-west or lateral communication between servers in the same tier or zone, but it has evolved to be used now for most of communication in virtual data centers.” As Gartner analyst Greg Young noted in a recent report, “Microsegmentation is the future of modern data center and cloud security,but not getting the microsegmentation-supporting technology right can be analogous to building the wrong foundation for a building and trying to adapt afterward.”
Unisys’ Patterson adds that the company is working to make Stealth more efficient and foolproof. “We’ve been able to take three or four ‘man months’ out of our install process and have replaced it with AI, making it point and click,” he says. Stealth users can expect two major updates each year going forward to keep pace with changes in the threat landscape as well as security regulation requirements.
