sandbox
Sandbox is a security mechanism for separating running programs. It is often used to execute untested code, or untrusted programs from unverified third-parties, suppliers, untrusted users and untrusted websites.
Unlike traditional antivirus solutions which can capture known malware, SandBox captures unknown files entering into the network and actively make execute and analyzing them in a secure cloud or virtual environment, where all observed unsafe actions are recorded and subsequently through active analysis identifies malicious files in minutes, on the basis of their actual behavior can correctly identify new or modified malware that may be unknown in this time.
