The 10 Biggest Cybersecurity Risks Businesses Face In 2021

Michael Novinson

From cloud misconfigurations and unsegmented networks to extorting ransomware victims and taking advantage of their cyberinsurance policies, here are the most significant risks organizations face.

Cloud Misconfigurations

Businesses have rapidly adopted Microsoft Teams and Office 365 recently without setting strict data collaboration policies, which has led to sensitive data getting shared broadly with outside third parties, said Matt Radolec, head of Varonis’ Incident Response team. Companies have less visibility and control over SaaS apps and IaaS and are mistakenly trusting the cloud service provider to deliver security.

Turning on an Amazon S3 (Simple Storage Service) bucket is as easy as flipping a light switch, meaning that businesses must implement a continuous monitoring methodology for their cloud apps, Radolec said. A single employee turning on one S3 bucket in the cloud could expose all of a company’s customer data to everyone in the world, according to Radolec.

Permissions are often configured differently for cloud services like Box as compared with storage arrays, with the settings adopted for a privileged administrator account in Box flowing all the way down to rank-and-file employees by default, Radolec said. Solution providers can help their customers build data protection programs and methodologies that apply best configuration practices to the cloud, he said.
