Even if data isn't stolen or published, it can still be viewed. That's what happened in The Great iCloud Hack of 2014, where nude pictures of celebrities were accessed and published online.īut the bigger risk with cloud storage is privacy. Cybercriminals can get into those files, whether by guessing security questions or bypassing passwords. "Whether data is being sent automatically (think apps that sync to the cloud) or driven by users uploading photos to social media, the end result is that it's all there somewhere being logged and stored," says Jérôme Segura, Senior Security Researcher at Malwarebytes.Īnd that somewhere is a place that's not in your direct control.Ĭloud security is tight, but it's not infallible. You are sending your data to another company, which could be saving your data thousands of miles away, so keeping that information safe is now dependent on them. You aren't saving files to a hard drive at your house. Why are people concerned with cloud security? Sign in for one service and find your entire library of documents and photos in another. If you use Gmail, you can access Drive anywhere you can access your email. When you save files to the cloud, you can access them on any computer, provided it's connected to the Internet and you're signed into your cloud services platform. These warehouses are guarded and managed by companies capable of housing massive loads of data, including the likes of Google (Google Docs), Apple (iCloud), and Dropbox. Instead, it's a system comprised of thousands of servers typically stored in a spaceship-sized warehouse-or several hundred spaceship-sized warehouses. The cloud is not just a few servers strung together with Cat5 chords. When you save files to the cloud, they can be accessed from any computer connected to that cloud's network. (And a server is simply a computer that provides data or services to other computers). That file is only stored on your computer, unless you decide to email it to yourself or save it on an external hard drive or USB.Īt its most basic level, "the cloud" is just fancy talk for a network of connected servers.
It lives on your hard drive, possibly housed in a set of folders you've created and organized yourself. It's pretty simple to understand where a file goes when you save it on your PC.
