How do cloud access security brokers (CASBs) enhance cloud security?

Cloud Access Security Brokers (CASBs) enhance visibility and control over cloud applications and data security through various mechanisms:

1. Visibility: CASBs provide visibility into shadow IT and unsanctioned cloud usage by monitoring user activities, data movements, and usage patterns across cloud applications. They offer insights into the use of cloud services, enabling organizations to gain a comprehensive view of their cloud environment.

2. Access Control: CASBs enforce access control policies to ensure that only authorized users can access specific cloud applications and data. They can also apply granular controls based on user roles, devices, locations, and other contextual factors to prevent unauthorized access.

3. Data Protection: CASBs use encryption, tokenization, and data loss prevention (DLP) techniques to protect sensitive data stored or accessed in the cloud. They can monitor data in real-time, enforce encryption policies, and prevent data leaks or unauthorized sharing.

4. Threat Detection: CASBs employ threat intelligence and behavior analytics to detect anomalies, suspicious activities, and potential threats within cloud environments. They can identify security incidents, malware, insider threats, and compliance violations for quick remediation.

5. Compliance Monitoring: CASBs help organizations maintain regulatory compliance by monitoring and enforcing data protection regulations such as GDPR, HIPAA, PCI DSS, etc. They provide detailed audit logs, compliance reports, and governance tools to demonstrate adherence to regulatory requirements.

Overall, CASBs play a crucial role in enhancing visibility and control over cloud
