Cloud Access Security Broker
A Cloud Access Security Broker (CASB) is a security policy enforcement point that sits between cloud service users and cloud applications to monitor activity and enforce security policies. It provides visibility into cloud usage, data security, threat protection, and compliance across multiple cloud services, including SaaS, PaaS, and IaaS. CASBs help organizations secure their data and applications in the cloud by offering features like encryption, access control, and anomaly detection.
Developers should learn about CASBs when building or integrating applications that rely on cloud services, especially in regulated industries like finance or healthcare, to ensure data protection and compliance with standards like GDPR or HIPAA. It is crucial for implementing security measures in multi-cloud environments, preventing data leaks, and managing shadow IT by providing centralized security controls. Use cases include securing sensitive data in SaaS applications like Salesforce or Office 365, and monitoring user access to cloud resources in hybrid infrastructures.
