Virtualization promises to cut costs and boost efficiency. This makes it an important element in your IT department’s constant efforts to do more with less. Whether this involves running applications on virtual or physical machines, users still need to stay vigilant and guard against the constantly growing hazard of cyber threats and malware at all times, because they can place businesses at great risk.
Virtualization Benefits for All-Size BusinessesIn today's highly competitive environment, virtualization is no longer only restricted to multinational enterprises and large-scale data centres. Virtualization promises to help with the following:
- Enable more applications and services to run on fewer servers
- Reduce hardware acquisition costs
- Decrease operational costs that are related to energy, maintenance and space
Virtual Environments: More or Less Secure?It is a widespread myth that virtual security environments are somehow more secure than their physical counterparts. Although there is no logic or truth behind this mistaken belief, some organizations can be lulled into a false sense of security when they consider the security requirements for projects requiring virtualization. Simply using a firewall for your virtual machine is never enough. Attackers that have breached the security perimeter of organizations will definitely regard unprotected machines as easy targets.
Using Existing Security PoliciesThe applications and services delivered by the IT department of organizations are important. This is regardless of whether they are run on virtual or physical machines. If an organization has recognized the need to protect its data and applications that are running on physical servers, the same need applies to business processes or applications that operate in an environment that is virtualized. Obviously, cyber criminals will focus on attacking your weak links. When organizations replicate current security policies, they introduce security gaps, introduce system inefficiencies and greatly increase IT costs.
Agent-Based and Agentless Security SoftwareAn agent-based security software is the same kind of package that would be installed on a physical machine in a non-virtualized environment. In such instances, the complete security software agent and the anti-malware database are installed on the machine. This could lead to potential gaps in security that include panic attacks, scanning storms, update storms and instant on gaps. For agentless security software, users can access file systems on virtual machines. Such products can protect virtual desktops and services without having a significant impact on hypervisor performance. With agentless solutions, IT departments can achieve higher guest virtual machine densities, higher return on investment and better performance for critical applications and business processes.
