CASB (Cloud Access Security Broker)

Cloud Access Security Broker (CASB) is a security policy enforcement technology positioned between corporate users and cloud service providers.

 

In more detail, it is a security solution that acts as a security intermediary between cloud service users and cloud service providers, monitoring all activities while serving as an intermediary among applications and enforcing security policies, whether they are managed on-premises or in cloud-based environments.

 

The ability of CASB technology to address security gaps extends to Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS) environments.

 

It provides various solutions to ensure cloud application security, such as authentication and identity matching, to secure cloud applications on devices that cannot be managed by authorized applications or authorizations. Additionally, it encompasses security solutions such as authentication, Data Loss Prevention (DLP), and malware detection.

 

CASB (Cloud Access Security Broker) is a software or service for cloud access security. CASB solutions help organizations control, monitor, and secure access to cloud-based services (e.g., SaaS applications, IaaS, and PaaS providers).

 

Below are some of the key functions of CASB:

 

1. Data Protection and Encryption: CASB protects and encrypts data stored in cloud-based applications, preventing unauthorized access to sensitive data and preventing data leaks.

 

2. Access Control: CASB allows organizations to determine who can access cloud services and what functions they can perform. It manages user and device authentication, access policies, and authorization rules.

 

3. Shadow IT Detection and Control: CASB monitors and controls the use of shadow IT within organizations. It prevents employees from using unauthorized cloud applications and identifies activities that do not comply with the organization's security policies.

 

4. Security Incident and Threat Monitoring: CASB monitors security incidents occurring in the cloud environment and detects threats. It identifies anomalies and potential attacks, providing protection against these threats.

 

5. Application Security Assessment: CASB helps organizations assess the security practices of cloud service providers. It identifies security vulnerabilities and guides the process of addressing non-compliance.

 

CASB is an important tool for organizations that want to address security and compliance concerns while benefiting from the flexibility and efficiency provided by cloud-based services.
