Protecting The Cloud

For many reasons, securing cloud environments such as AWS, Microsoft Azure and Google Cloud is a major trouble spot for organizations. Lack of visibility, a massively expanded attack surface and the highly dynamic nature of the cloud are just a few of the big issues facing security teams who are charged with protecting cloud-based resources. As just one indicator of their struggles, cybersecurity professionals who were surveyed at the RSA Conference in April reported that their biggest concern is cloud security, beating out worries about ransomware and remote work, according to a report from access management vendor Delinea.
