PETALING JAYA: More organisations are virtualising their servers and desktops in order to save cost and now they are facing the challenge of managing and securing these virtual environments. And it isn’t always an easy task, according to security specialist Symantec Corp.
Nigel Tan, principal consultant for Symantec Asia South, said virtualising the first 20%-30% of a server infrastructure is easy because companies tend to start out with non-business-critical applications first.
“They’ll start facing more difficulties later when they decide to virtualise their more critical applications,” he said during a media briefing at Symantec Malaysia’s office here.
According to the security vendor, nearly half of the data on virtual systems are not regularly backed up. Based on the information from its 2010 Disaster Recovery Study, only 20% of virtual environments are protected by replication or failover technologies, and 60% of these are not covered in disaster recovery plans.
Organisations need to secure their data and infrastructure, ensuring users can access that data and deal with storage problems as the amount of data grows. Symantec has solutions that deal with these challenges.
To secure servers, Symantec offers the Symantec Endpoint Protection and Compliance for Virtual Environments that protects virtual machines from malware and security threats.
Koh Ee Laine, senior technical consultant at Symantec Malaysia, said the solution is able to run scans without slowing down work processes.
She said the need for this feature arises from potential performance and bottleneck issues when scans would start and run simultaneously on host machines running multiple VMs (virtual machines).
“This feature corrects that bottleneck and ensures scans are not started simultaneously in multiple VM environments, thus greatly improving overall performance,” Koh said.
The solution has also made life a little easier for IT administrators because it can also scan offline VMs.
“Traditionally, VMs needed to be booted up before they can be scanned for malware, but now this can be done even when the VM is inactive,” she said.
