Security of Virtual Machines

The sorry state of technology related security is oft repeated and generally accepted. Since virtual machines have pretty much become part of the furniture of all businesses, both large and small, securing the data within these machines is becoming a growing concern for business owners.

Virtual machines are relied upon for their efficiency in managing large amounts of customer data, transactions and various applications which is used by a business. In other words, according to computer and technology news, virtual machines have become the core component of every business.

Since hackers can easily find ways to jump the hypervisor to access any number of virtual machines on a host along with virtual desktops and virtual data backup or storage the following lines are going to be on some of the most common myths regarding security in virtual machines.

All Virtual Security Programs are the Same

While this might be true in some cases, the fact of the matter is that most businesses do need a combination of one or more virtual security programs in order to get the best protection possible. In the end, it all comes down to what you are trying to protect. For instance, a non web server is going to require a completely different set of security programs as compared to a virtual desktop, which is used to manage information. This is where one needs to educate themselves with the different kinds of virtual security programs out there, such as, agent-based, agent-less and light agent.

The Use of Non-Persistent Virtual Machines

In an era where malware is being designed to survive the tear down of individual virtual machines, creating new machines only result in them eventually being forgotten. This not only leads to a virtual machine which is unmaintained, but also to a virtual endpoint operating which is in existence without the knowledge of the IT department.,55402453.html,55402461.html

But Virtual Environments are more Secure

While it could be in theory, the reality is quite different. The reason being that virtualization has been designed to allow software to behave as they would in normal situations. This includes malware, which is after all, software as well. In order to get to their goals, hackers usually target every weak access point they can find in a business IT network.

Will Anti-Malware Interfere with Virtual Operations

The truth is that certain performance issues can create gaps that did not exist in the system, and these security gaps can be taken advantage of b criminals who want access to your business data. Normally, endpoint security uses an agent-based model which basically means that each virtual and physical machine has a copy of the security program on it, which communicates with the server while performing security tasks.
