What Is CASB

Cloud Access Security Brokers or CASB are the cloud-hosted or on-premises applications, which sit in between the consumers and providers of cloud services. These are applied to enforce compliance, security, and governance policies on the cloud programs. They help an organization to extend their security controls from on-premises infrastructure to cloud.

  2. Compliance: Capability of determining confidential items stored in cloud and enforces data loss prevention policies for meeting the requirements of data residency and compliance.
  3. Data Security: Security practices like tokenization, encryption, access control, and information rights management are enforced for being safe and secure on cloud.
  4. Threat Protection: Instantly determines and responds to the negligent or harmful insider threats, compromised accounts, and privileged user threats.

What Is CASB Solution Benefits?

The benefits explained here are from the perspective of enterprises who adopt cloud infrastructure. Organizations will be having following advantages after implementing cloud access security broker solutions:

  • Based on user’s device, operating system, and location, CASBs impose different agreement levels for data accessing and cloud services functionality.

What Is CASB Use Cases?

In an enterprise, there are several use cases available and they are explained below:

Secure Shadow IT: The very basic and important major case that comes to the mind of business users is Shadow IT. It is considered as an unauthorized use of the cloud services either by an employee or any other individual of the firm. Enterprises are not aware of the fact that Shadow IT is not discovered to compromise security, governance policies, and compliance. With the help of CASBs, organizations will be able to protect their data by discovering security measures for limiting the access outside the firm.

No matter whether the activities are carried out from the mobile app or computer programs, an administrator will be able to view data accessing with its user. These practices help in governing access to the public cloud services through the class of device ownership with monitoring of privileged accounts and prevention of the unauthorized cloud activity.

Sensitive Data Security: CASB cloud access security is capable of preventing data exfiltration from sanctioned to unsanctioned cloud services. This involves:

  • Enforcing several policies for personal as well as business instances of the similar cloud services
  • Enforcing a policy on the activity or data level across the services category
  • Enforcing the conditional policies on activity-level with layered policies, as well

Block Malware Threats: This cloud security solution blocks or remediates malware in managed cloud services and to and from unsanctioned cloud services. It determines and gives an alert message to the enterprise about anomalies user login and notices anomalies like excessive downloading, file uploading, sharing between cloud services, and prevents the infiltration of data including new employees.

In What Form Does The CASB Exists?

Cloud access security brokers might execute on on-premises or on the cloud. Theoretically, the CASB sits in between the user and cloud but, in actual, this is located either in a data center of corporate or in the cloud itself.
