9 Ways to Protect Your Cloud Environment from Ransomware

The same technology driving faster collaboration and data transfer also enables cybercriminals to quickly spread ransomware.

Separate data storage

Shpantzer advises knowing where your formal and informal assets are located -- a common oversight but important step in planning for and addressing a ransomware attack.

He explains how, for example, many developers are spinning up servers in the cloud for quick testing, but aren't fully aware of the security and compliance implications of doing so. Sometimes they expose full copies of production databases, a mistake that adds confidentiality issues in addition to the ransomware and availability issue.

"Know what's on your formal assets and understand shadow IT and how to mitigate it," Shpantzer says.

For restoration, he advises using cheap cloud storage to grab snapshots, files, folders, and anything you need to reconstitute your operations. Store them in cold storage on a separate MFA-protected account.

"This is about disaster recovery, not just an intrusion incident where someone merely copied PII and left your network and data otherwise intact."

Reavis also recommends separate data storage, specifically offline backups, to stay safe in the event of an attack.

"We are all using real-time cloud storage, which is great," he says. "But the fast autosyncing means that all your copies are infected as well, so it isn't a replacement for the extra effort to schedule backups regularly."
