Just like the name says, mobile security deals with keeping your smartphones and similar devices safe from security threats and vulnerabilities. There’s a lack of corporate control over employees’ personal devices thanks to the increasing BYOD phenomenon, and that comes with a risk factor. Employees will more than likely use their devices to connect to enterprise servers, and sensitive data will be stored on them as a result. That’s why it’s imperative for companies to develop sophisticated methods for securing that data and ensuring that no breaches occur and no information is stolen.
So how do we counter these threats? For starters, you can make the operating system secure. Sandboxing is one way to do this. This involves breaking up processes into different compartments so they remain isolated from each other—if one gets infected, it won’t damage anything else because the virus will be self-contained. iOS, for example, will only allow apps from the App Store—which, of course, Apple regulates rigorously—to access its API.
Another method, and probably the most intuitive one, is to have preventive software installed on your device. Now whether that could range from antivirus software to a firewall, implementing a captcha (which only a human can solve) to screen user decisions, even biometric identification—stuff like face or eye recognition. All of those methods would make getting access unique to the sole owner of the device and thus solve the issue of possible security threats.
And then of course you could just monitor what’s going on on your device. Check the battery—if it’s draining all of a sudden for no apparent reason, there might be malware sucking it up. Same goes for a spike in memory usage, or an unfamiliar service or process running in your processes manager.
