What is a CASB (cloud access security broker)?

A cloud access security broker is an integral cybersecurity tool. It can be thought of as a middleman between an organization’s infrastructure and the cloud provider. Cloud computing or providing is an on-demand service that allows the remote use of computing resources. The most common resources are data storage and processing power. What a CASB does is act like a bodyguard to ensure that the organization can control and administer their security policies over a different infrastructure.

The cloud is getting more popular by the second as we go into 2020. Almost all services are migrating into cloud storage and processing, making the task of protecting the data even more daunting. Think of it as the main control unit that can allow the exchange of information safely by applying security measures and policies as if it’s within the physical enterprise itself. We’ll be giving you a brief summary of how CASB works, in addition to the different types and applications available.

Why organizations choose to use a CASB

The IT department views CASB as a window that provides visibility into the cloud activity of the employees on any programs, apps, and data in an organization. The overflow of information, if left unmonitored, would be hard to know who has permissions of access, where the data is being stored, and what kind of information is being passed around, whether it’s confidential or not. There are different types of CASB that allows the customization of access to different data. Organizations choose to streamline their network security using by managing and monitoring risks.

Data loss prevention and encryption

Data loss prevention means not only locating and identifying the most sensitive data across the servers, but also classifying it to make sure this data isn’t lost in an accident or an intentional attack. Administrators of the CASB are able to easily find confidential information like credit card numbers and serial numbers across all governed platforms. The security of data is maintained by encrypting the files before it reaches the cloud servers. This makes sure that the system is less vulnerable when the devices are synced to the cloud.

Import features of CASB

A common feature CASB facilitates is the single sign-on; it basically gives permission to a user to log in or access multiple platforms with a single sign-in. CASB can use access control to restrict access to any specific file, it can even reach complete restraining of access of choosing mobile devices as well. This is commonly used when an employee is being removed or terminated from the organization or if a device is lost or stolen.

The crawl toward cloud services has transformed into a frantic run to adopt it as it has become the mark of new-age computer processing and data storage. Floating information is harder to protect than information secured within the infrastructure of the enterprise. CASB is developing rapidly as more organizations and online entities are aware of how important it is to secure the exchange of information and data between cloud servers and user devices.
