The benefits of virtualized servers include reduced IT spending, data center space, energy costs, desktop and server provisioning and more. Despite these benefits and the estimation that the worldwide cost of cybercrime will reach $6 trillion annually by 2021, virtualization poses new risks to the data center. Read about the top 4 virtualized server threats and what you can do to mitigate your risks.
1.) Virtual machine escape
While rare, the most serious threat to virtual machine security is a hacker targeting hypervisor vulnerabilities with a virtual machine escape. It allows an OS running within it to interact with the hypervisor, providing hackers access to the host operating system. Make it a priority to regularly look for and apply vendor patch updates to reduce exposure.
2.) Administrative access
Despite virtualized platform efficiencies, they add management complexity. To protect against hackers who may ultimately access data center resources, secure management interfaces by tightly restricting access to the management interface.
3.) Network Compromise
Unusual inter-virtual machine activity or sources could be signs that your network is compromised. Create monitoring strategies, including preventive measures, intrusion detection and containment, to watch your data center networks for the slightest sign of connections from unfamiliar or unauthorized sources.
4.) Network eavesdropping
In older data centers, physical switches are used to prevent network eavesdropping. In a virtualized data center, virtual switches should be designed to isolate network traffic by routing it through its respective security levels before it’s connected to the corresponding switching ports.
