Windows 10 Linux Feature Brings Real, but Manageable Security Risks
NEWS ANALYSIS: The Bash shell support in the Anniversary Update for Windows 10 is a valuable tool for developers, but it needs to be used carefully because of potential security risks.It should have come as no surprise when it was revealed at the Black Hat USA conference that Windows 10's ability to run some Linux commands through the inclusion of the Bash shell command language also created a security risk. The fact is that any time you introduce a new way to interact with software as complex as Windows 10, you will also introduce new avenues for a security breach. The more important questions are: How serious is the potential breach and how likely is it to be exploited? It's not likely to be exploited mainly because the Ubuntu Linux command line isn't enabled by default in Windows 10 and few users will find and enable it, unless they are developers or perhaps hackers who want to do something nefarious. Without the Bash shell and the accompanying command line, there's no way to use the Linux commands to launch a cyber-attack. But the fact is that the Bash shell does exist, and unless you've set up your company's computers so that users can't access the setting that turns it on, you could find yourself with employees who want to experiment with the new capability.
Just so you know where to find it, this is how you enable the Windows Subsystem for Linux. First you open the Settings function, which is now represented by a gear icon when you press the Start button. Then you go to Updates and Security and click on the For Developers choice.
