How Does Sandboxing Work?

Sandboxing, as the name suggests, isolates untested code away from the production environment. In the isolated environment, different variables can be shifted and played around with only until a solid program is verified in order to be deployed in the actual user environment.

Sandboxing is a network security measure that lets you run code, observe, and analyze it in an isolated and safe environment that simulates operation in the real end-user space. Sandboxing is used to test out any new or untrusted code before it is deployed onto the actual user environment. Failure to the practice, untested pieces of code may provide a backdoor for malware attacks, interference, and manipulation of our systems, or worse -unprecedented system crashes.

Sandboxing detects, analyses, and helps fix malicious or unsafe programs without compromising the current operating systems or host devices and proactively fixes any threats. In a sandboxed environment, applications are permitted only to use a limited storage area and memory while restricting access to all other system resources.

 How to Implement Sandboxes

Sandboxes can be deployed in a variety of ways.

Hardware/appliance-based Implementation – Appliance implementation necessitates the need for localized servers and all other network devices. In extreme cases of restricted isolation, the sandbox would require separate network and ISP connections, making it relatively expensive. This implementation is slowly getting replaced by cloud for a number of added advantages(below).

Software/cloud-based Implementation – Software implementation provides the advantage of remote working and eliminates the hardware costs. Code can easily be tested on-demand over virtual environments completely away from other host devices. Also, the cloud-based implementation allows for cheaper expansion as the future necessitates.

A web Browser Extension/ Browser Sandbox – Most browsers(chrome, Mozilla, Microsoft edge) nowadays come with their own sandboxes. The functionality was innately crested to safeguard websites since they are the most targeted avenue for attacks. If a website downloads malicious code, it is downloaded to the sandbox, and when the sandbox is closed, everything inside is erased, including the mischievous code.

The Benefits of Sandboxing

Deploying sandboxes has a number of benefits.

1.    Safeguards our Network Host devices and Operating system from risk – One primal advantage of sandboxing is its ability to isolate a test environment and, by doing so, maintain system optimity while testing new programs.

2.    Evaluates the system for any Possible Threats. In case you are working with new vendors or uncertified software resources, you could test them in the sandbox prior to implementing them in the user environment.

3.    Proactive Remediation – While in the sandboxed state, all defects in programs are listed out, prompting immediate remediation before going live

4.     Eliminates Zero-Day Threats – A zero-day attack in technical jargon refers to the process of launching an attack on the very same day a threat was discovered. Vulnerability is maximized more in this scenario before a creator is allowed to fix their bugs. With sandboxing, software creators have the opportunity to fix these issues before going live.

Drawbacks to Sandboxing

Inasmuch as sandboxing provides all these security reinforcements to a system, it still can be limited in the following instances.

1.    Limits and Applications Capabilities – As explained earlier, a program in a sandbox is only allowed for access to predefined memory and storage. This setup implies that at any given time under test, programs capabilities are limited in terms of utilities

2.    It is Time Consuming – Running all your system processes in a sandbox can be time-consuming and impractical, especially for high-traffic businesses.

3.    Sandboxing can be Dodged – As sandboxing gets popular in the business environment, hackers have devised means to bypass the algorithms. For example, malware may be programmed to remain dormant in virtual environments up until it is launched live.

How Do I Choose the Right Sandbox?

There are numerous vendors in the market today, each claiming to provide the best solution. The best bet you could take is to select a sandbox that has been globally tested and reviewed. Do not naively rely on the vendors’ manifesto for performance.

Sandboxing will not provide a one-stop solution for all your security needs. It is more effectively complemented with firewalls, Intrusion detection systems, and virtual private networks.

Least to say, cloud sandboxing has proven to be the best option around. Especially now, in the wake of Covid-19, most of us find ourselves working remotely outside of the office network. One given is; once a user leaves the company network, they are predisposed to so many threats, having a cloud sandbox could protect all organizational resources regardless of geolocation.
