How To Overcome Common Virtualization Security Concerns
Virtualization is becoming a staple of businesses of every size. According to a Cisco survey, 77-percent of small to medium businesses have already virtualized part of their infrastructure. In the next two years, the virtualization budgets will increase for about 70-percent of all businesses. As Sam Narisi, of IT Manager Daily writes, virtualization allows companies to save money while increasing flexibility and scalability, but there are some security concerns. Here are the top three security issues associated with virtualized services and how to overcome them.
- Limiting Access
Many organizations host multiple virtual machines on a single physical machine. This is the nature of virtualization and why it is so popular. This opens the door for devastating attacks, however, if the virtual machines aren’t properly separated. It’s important to grant employees access to only the VMs they need. This way, if their access is compromised, your entire virtualized infrastructure isn’t.
Any software will contain bugs and vulnerabilities that can be exploited by intelligent hackers. Virtualization software is no different, but allowing a hacker to use these vulnerabilities could prove much more costly than other software exploits. Patches and updates are constantly being made available to fix these flaws. It’s important to stay current and update your software each time a new patch is released so you can close holes in security before an attack takes advantage of them.
More than ever before, it’s important to have a firm grasp on the IT assets in existence and who has access to each in your company. This was a simpler job when each machine was physical. With virtualization, VMs can be created and moved quickly, which sometimes leaves IT out of the loop. If a problem comes up, it’s much easier to solve it when you know where each machine is and who is able to access it.
Virtualization offers a number of benefits for businesses, but it also comes with increased responsibility and security concerns.
