Malware is becoming more sophisticated every day, and we recommend several solutions for dealing with it. One of the most interesting of these is achievable via cutting-edge virtualization technology. Often referred to as sandboxing, this solution is a great way to quarantine and test suspicious applications before exposing them to your entire network.
What is sandboxing?
Sandboxing is one of the rare concepts in virtualization that the average person can usually grasp in just a couple short sentences. Essentially, sandboxing is the practice of tricking an application or program into thinking it is running on a regular computer, and observing how it performs. This is especially useful for testing whether unknown applications are hiding malware.
Obviously, it gets far more complicated once you delve into the details of how you implement a sandboxing technique, but the short answer is that it almost always involves virtualized computers. The program you want to test thinks it’s been opened on a full-fledged workstation of server and can act normally, but it’s actually inside of a tightly controlled virtual space that forbids it from copying itself or deleting files outside of what is included in the sandbox.
An effective way to quarantine
Virtualization is no simple task, but the benefits of sandboxing definitely make the effort worth it. For example, virtualized workstations can essentially be created and destroyed with the flip of a switch. That means:
- You aren’t required to manage permanent resources to utilize a sandbox. Turn it on when you need it, and when you’re done the resources necessary to run it are reset and returned to your server’s available capacity.
- When malware is exposed inside a sandbox, removing it is as simple as destroying the virtual machine. Compare that to running a physical workstation dedicated solely to sandboxing. Formatting and reinstalling the machine would take several hours.
- Variables such as which operating system the sandbox runs, which permissions quarantined applications are granted, and minimum testing times can be employed and altered in extremely short periods of time.
This strategy has been around for nearly two decades, and some cybersecurity experts have spent their entire careers working toward the perfect virtual sandbox.
Containers: the next step in this evolution
Recently, the virtualization industry has been almost totally consumed by the topic of “containers.” Instead of creating entire virtual workstations to run suspicious applications in, containers are virtual spaces with exactly enough hardware and software resources to run whatever the container was designed to do.
Think of the metaphor literally: Older sandboxes came in a uniform size, which was almost always significantly larger than whatever you were placing into them. Containers let you design the size and shape of the sandbox based on your exact specifications.
Quarantined virtual spaces fit nicely into the sandbox metaphor, but actually implementing them is impossible without trained help. Whether you’re looking for enhanced security protocols or increased efficiency with your hardware resources, our virtualization services can help. Call us today.
Instead of an outright operating system update, Microsoft is now releasing named updates that come with enhancements and other features that individual users and businesses should get excited about. Its latest, Creators Update on Windows 10, includes new design touches and a handful of productivity features. Are the new features worth the updates?
Keeping your laptop plugged in all the time doesn’t solve your battery problems. It may keep your laptop fully charged for a day, but this practice may do more harm than good in the long run. Luckily, there are quick-and-easy fixes and long-term solutions to help save battery power on your laptop. Here’s a look at some of them.
