A sandbox is a secure, isolated and a tightly controlled environment where programs can be run and data can be protected. Sandboxes restrict what a piece of code can do, giving it just as many, permissions as it needs without adding additional permissions that could be abused.

 Prevent malicious or malfunctioning programs from running

Malware — short for malicious software — refers to various types of programs written with the purpose of gaining access to a computer for malicious intent, and often without the user’s knowledge. Malware comes in a variety of forms, such as viruses, spyware, adware, ransomware, and Trojans.There are a number of ways that your device can be infected with malware, but many times it comes from a malicious website, or open the attachment file from your email. By default, anything you download from a web browser will normally go to the %appdata% Downloads folder on your computer.

To prevent the malware from running in the first place, you can setup the sandbox with the policy which not allow the binaries inside the sandbox being launched for those folders where will store the malware, for example "C:\Users\Username\AppData\Local\Temp", "C:\Documents and Settings\ username \Local Settings\Temporary Internet Files". With the sandbox protection, you never have to worry about suspicious attachments or spear phishing attacks, you are safe to download the files from your web browser or you are safe to open your attachment from your email, because of the malware never be launched without your permission.

1. Prevent or restrict the executable binaries running

a. Setup secure sandbox folder filter mask, i.e., c:\sandbox\*, this is the folder which the executable binaries located.

b. Allow the binaries being executed if you want to test the binaries, or disable the execution of the binaries to prevent the untrusted processes from running. For example, you can setup a sandbox for the download folder to prevent the untrusted download binaries from running.

c. If you allow the binaries to run, you can also allow or deny the binaries to access or change the registries. To protect the registries being changed by the binaries, you can disable the registries changing feature.

d. Setup the specific file access rights to different file folders for the process. By default, set the least access rights for all files to the process, then if you want to allow the process to access some specific folders, add these folders with specific rights to the process as the below image, allow the process with read access to the folder c:\windows, allow full rights access to the folder c:\mysandbox.
