CASB - Cloud Access Security Brokers
A Cloud Access Security Broker (CASB) is a security check point between cloud network users and cloud-based applications. They manage and enforce all data security policies and practices, including authentication, authorization, alerts and encryption. CASBs improve an organization’s visibility as to who is accessing their data and how it is being used across endpoints.
4 pillars of CASB
Visibility
- Gaining complete visibility into cloud usage across all services, both sanctioned and unsanctioned.
- Monitoring user activity and identifying suspicious behavior.
- Gathering information on all access requests to cloud data.
- Obtaining detailed insights and reports for identifying potential data leaks.
Compliance
- Ensuring adherence to industry regulations and internal security policies.
- Implementing data loss prevention (DLP) controls to prevent sensitive information from leaving the organization.
- Providing logging and audit trails for compliance reporting purposes.
- Managing access to cloud services based on user roles and permissions.
Data Security
- Protecting sensitive data from unauthorized access, modification, and deletion.
- Implementing encryption at rest and in transit for all cloud data.
- Using tokenization and other data masking techniques to further protect sensitive information.
- Controlling data sharing with third-party applications and services.
Threat Protection
- Identifying and preventing malware and other threats from infiltrating the cloud environment.
- Detecting and responding to data breaches and other security incidents.
- Implementing anomaly detection to identify suspicious user activity.
- Utilizing sandboxing to safely test and analyze unknown applications.
