The last several years have seen an unprecedented shift in the way that businesses conduct their operations and employees perform their work. Users are no longer confined to working on premises from desktop computers. Data is being accessed, stored, shared, and processed in new ways. While these changes have enhanced productivity and collaboration in the enterprise, organizations must consider how they are affecting cybersecurity.
Software-as-a-service (SaaS) applications like Office 365, Box, and Salesforce have forever changed the IT landscape. Likewise, infrastructure-as-a-service (IaaS) platforms like Amazon Web Services (AWS) have had massive impacts on organizations around the world. However, all too often, their native security functionality is lacking. Making matters more challenging is the fact that traditional, on-premises tools are unable to extend their protections to cloud environments. When the above is combined with the fact that employees are accessing corporate IT resources and performing their work from personal and mobile phones around the world, the picture becomes even more complex.
Security measures must be tailored to this new environment as well as granular enough to provide the intelligent, contextual security that modern organizations need. Securing access to data based on who, what, why, how, and where is now critical. Some users may not be authorized to view certain kinds of files, while some data should only be accessed from certain geographical regions or types of devices––there are a multitude of considerations that must now be addressed. Fortunately, solutions like cloud access security brokers (CASBs) are designed to protect data in our cloud-first, mobile world.
