Don’t wait for a hack to happen: Secure your business data now
Just yesterday my phone auto-synched 50 (yes, 50- no shame) pictures of my dog to Dropbox and I uploaded my personal budget for the month to Google Drive. We do this sort of thing without thinking- and sometimes without even opening an app. We use the cloud without a second thought. In fact, a billion files are uploaded to Dropbox alone every day. And this isn’t just personal files. This is business files, too.
Are you mindlessly uploading everything you’re working on at the office? Are your folders auto-synching as a pc backup method? If so, you aren’t alone. 56% of Fortune 500 companies use the paid function of Dropbox and over 3 million businesses pay for G Suite, which includes Google Drive. Companies everywhere are deploying these cloud file-sharing services to increase employee productivity. And, there’s no wonder why. They’re convenient, low-impact, and relatively low-cost services.
But, see, the problem comes in when we start using these tools at work to store high-stakes, sensitive files- think customer lists, code for your not-yet-launched new product, or even business results. Are you storing these files on Google Drive or even Dropbox and inadvertently putting your company at risk?
Here’s what you need to watch out for.
- Auto-synching shared files to the cloud can create security vulnerabilities. Often company files are shared among teams through cloud file-sharing services. But imagine if one of your co-workers has a file that’s been compromised by ransomware or other malware. If that file is then synched into a cloud like Dropbox or Google Drive, you could have a problem. Dropbox won’t be able to detect this as an infected file; it will just be uploaded as normal. Good news is Google Drive does scan your files and will give you a warning before upload. But either way, this malware could be synched down onto your pc, infecting not only your co-worker's pc, but yours too. This means a small virus could turn into a company-wide security breach.
- Confidential files could be at risk. Who has access to your files? Are they set to private or public? Often entire folders will have default permissions, and it can be easy to accidentally give broad access to a file or folder unintentionally. When file-sharing services are used in business, this concern is amplified. Customer data, sales reports, or other sensitive company data could be at risk. Consider large customer lists. These might be too large to share over email, so you upload to Dropbox. But you’re quickly in trouble. With GDPR, you could now be facing fines up to 20 million Euros if that list contains names from Europe. It’s now even more critical to scrutinize file access on cloud services.
There are certainly benefits to using file-sharing services like Google Drive and Dropbox at work, but they aren’t without fault. Understand the security risks, especially when storing sensitive business data, so you can work to prevent hacks before they happen.
