How & Why To Manage The Security Of Virtual Servers
Monday February 14, 2011
More information security analysts are now noting that the speed and ease of deploying virtualized environments has resulted in many IT enterprise shops overlooking security issues. With the ability for enterprises to launch many virtual servers, these security analysts are concerned that IT teams are not addressing security concerns in the virtual environment. They contend that it is vital for IT shops to pay attention to the potential security risks and take steps to stay ahead of threats that could compromise their servers.
One potential concern among IT security analysts is the sudden appearance of many virtual servers without knowing where these servers came from and the purpose of these servers. Analysts suggest that IT shops need to understand and take measures to prevent security vulnerabilities. This involves making sure control of access stays limited to certain assigned users so that there are not a large number of people in the business having access to data that the company wants contained to a select few. Analysts suggest that to resolve the problem, there should be a senior official in charge of assigning access to the appropriate employees and addressing such issues as identifying what servers employees can work with and what servers they cannot access. By setting such security standards into an effective security policy, it will prevent someone from potentially take down the entire system, whether intentionally or accidentally.
Today, the move to virtualization is drastically increasing in many different industries. As virtual machines move into production, security becomes a vital issue. When enterprises deploy virtual servers in production, servers are pooled together, provisioned, and then deployed from a small number of standardized operating system images. They are then dynamically moved around to respond to changing server and enterprise demands. They definitely benefit from the flexibility associated with virtualization; however, the virtual operational practices implemented require a new approach to security.
To benefit from server virtualization, an enterprise must adopt security measures that are both flexible and dynamic. Tracking, monitoring, and maintaining the virtual servers that include keeping track of what is on the servers is vital to maintaining efficient server security. Because server provisioning and deployment is now easier and faster than ever before, with the ability to launch hundreds of virtual servers, IT shops need to be mindful of security threats and take measures to ensuring all virtual servers are secure.
