According to Symantec, a top securities firm, "Vulnerabilities in cloud infrastructure provide the next frontier for cyber crime".
An example of cloud security issues. A growing reliance on cloud services creates vulnerabilities for organizations. Tens of thousands of MongoDB (cloud) databases were hijacked and held for ransom in 2016 after users left outdated versions exposed, without authentication turned on.
CIOs have lost track of how many cloud apps at use in their organizations: their guess was 40, when in reality the number nears 1,000. Ungoverned access and shadow IT present significant risk. Symantec predicts that unless CIOs get a firmer grip on the cloud app usage and access, attackers will exploit these cracks in the cloud.
