The in-built Windows Defender that Microsoft distributes with its operating system is a widely used anti-virus, anti-malware utility, and there are many users who solely depend on it, without going for any other product in the market, free or otherwise. Defender is now going for a big, thorough overhaul, indicates a Windows Insider preview of the software. Microsoft is planning to have it run in a sandbox, to make it more secure and efficient. Sandboxing is not a new technology at all, Google Chrome has been using it since 2008. A sandboxed application functions in isolation from the rest of the software on computer, and if something goes wrong, it prevents the damage from affecting the other applications.
Microsoft points out that the new Defender would be the first complete anti-virus program to run in a sandbox. This would help it make the security features more efficient and near- total. Coding the program will be a difficult and complex procedure, asking for extreme care. It should be done in such a way that the program doesn’t bring the performance level of the computer down. There is the danger of that, as there will be a lot of traffic between the sandbox and the system’s operating system. There is a big chance that such activities will affect the performance of the computer, especially for those who use old hardware.
However, the protection offered by the new Defender will compensate for the lower performance level. This is crucial because an anti-malware app is in fact a backdoor that the user willingly sets up, based on a vague kind of trust. Such an app monitors every activity that happens in the system, including everything that is uploaded and downloaded. Also, when some suspicious activity is noted, many of these apps upload the details to a remote server for analysis. This can make them vulnerable, as when a hacker compromises the anti-malware app can track the details of the users’ internet activity, access their files, and even steal them. A program running in a sandbox prevents precisely this: it will be virtually impossible for a hacker to get past the sandbox when it is implemented. Thus, a sandboxed Defender will offer the kind of protection which none of the other players can do at the moment.
