Those are some of the big takeaways from a ThinkEquity report by Jonathan Ruykhaver. Here's a few more wallet-friendly options. Virtualization can be used in many ways and requires appropriate security controls in each situation. Another big takeaway is that enterprises could put off virtualization in the data center because of worries about security risks. As for now, attacks on virtual systems are extremely rare, because virtualization platforms are not widely spread. The section discusses several topics related to virtualization security issues, including VMs image management, virtual machines monitor, network virtualization, mobility, issues in virtual machine, and malware as seen in Table 5. "Each one of those virtual servers is still its' own separate server, though," MacDonald says. In the upcoming gift-giving season, these gadgets will tempt you to pick up the same present for yourself, too. Quiz: How Well Do You Understand Server Virtualization Benefits, Limits? Ruykhaver points out: One compromised virtual machine could infect all Virtual Machines on a physical server. Virtualization Security in Data Centers and Clouds . An attack on one guest virtual machine escaping to other virtual machine's resident on the same physical host represents the biggest security risk in a virtualized environment, in our view. manner Administrators tend to dismiss virtualization security issues, largely due to the nature of the technology. The National Security Agency has taken that concern not only to heart, but to software development labs, coming up with a virtual-server management scheme called NetTop that requires a configuration preventing VMs running on the same machine from interfering with one another. Seven physical systems (top) and a virtualized equivalent implementation (bottom). He said paying attention to the security configuration guidelines that Citrix and other hypervisor vendors publish can fix most of the security issues and that industry groups such as the Cloud Security Alliance can extend that guidance to include process-management and policy issues. 4 trends fueling hybrid-work strategies in 2021, Why ERP projects fail: Finding the gaps in your program plans, Carrier and AWS partner on innovative cold-chain platform, Customer-focused IT: A key CIO imperative, post-COVID, Phillip Morris CTO scraps bimodal IT for consumer-centric model, Perfect strangers: How CIOs and CISOs can get along, Virtualization Security: How the Masters of Mixing Protected Unique IP, 10 Virtualization Vendors to Watch in 2009, Sponsored item title goes here as designed.
