A company is implementing a cloud access security broker (CASB) solution. What is the primary security challenge that CASBs are designed to address in cloud environments?

  1. AManaging physical access to cloud provider data centers.
  2. BEnforcing security policies and governance across multiple cloud services.
  3. CAutomating vulnerability scanning for custom-developed applications.
  4. DProtecting on-premises data centers from external attacks.
Show answer & explanation

Correct answer: B. Enforcing security policies and governance across multiple cloud services.

CASBs act as a security policy enforcement point between cloud service consumers and cloud service providers. Their primary role is to extend an organization's security policies from their on-premises infrastructure to the cloud, addressing challenges like shadow IT, data loss prevention, and compliance.

Why the other options are wrong

  • A. Physical access is the responsibility of the cloud provider, not typically managed by a CASB.
  • C. While some CASBs may offer integration, their core function is not solely vulnerability scanning for custom apps.
  • D. This is a traditional perimeter security concern, not the primary focus of CASBs in the cloud.

Cloud Access Security Broker (CASB)

A security policy enforcement point placed between cloud service consumers and cloud service providers to combine and interject enterprise security policies as the cloud-based resources are accessed.

  • Addresses cloud security gaps and shadow IT.
  • Enforces data loss prevention (DLP), access control, encryption.
  • Provides visibility into cloud usage and compliance.

Memory trick: CASB is like a 'C'loud 'A'ccess 'S'ecurity 'B'ouncer for your data.
