What is Cloud Access Security Broker Umbrella?

When you’re choosing a cloud security broker (CSB), it’s important to know what options are available to you. Cloud access security broker (CASB) umbrella is one such option, and it’s been growing in popularity in recent years. But what is CASB umbrella, and how can it benefit your organization?

In this post, we’ll answer those questions and more. Keep reading to learn more about CASB umbrella and find out if it’s the right choice for you.

Cloud Access Security Broker Umbrella

Cloud Access Security Broker Umbrella is a security technology that can be used to monitor cloud-based applications at scale. Leveraging the cloud to allow a granular level of control over user privileges. Also, it is designed to help you address the challenges of securely extending your on-premises IT infrastructure into the cloud.

This is via Cloud Identity and Access Management. CASB can be used to control user access to cloud applications. How? Simply by leveraging cloud identities and access management solutions such as Okta, OneLogin, or Ping Identity. This allows organizations to establish a single sign-on environment for both their on-premises applications and cloud-based applications.

CASB is an effective way of enabling least privilege access control. That is for cloud-based applications to limit the exposure and risk from user privileges. In Cloud Application Security, the CASB can be used to detect and alert on inappropriate use of cloud applications. 

These are malware downloads, risky application configurations, and more. Moreover, Cloud Audit Logging is where CASB can be leveraged to collect activity logs from multiple SaaS providers. This is to generate a unified audit trail of user activity across all SaaS providers.

Least Privilege Access Control to Discovery

Cloud Application Discovery and Least Privilege Access Control is a feature that allows an administrator to grant only necessary access. That is to a user or group of users to each cloud application. Now the Cloud Application Discovery is the ability for a CASB to scan for applications in a particular cloud environment.

This is such as AWS and reports them back to the CASB. Cloud Application Discovery is especially important to identify new and existing cloud applications in your environment. Then you can be able to secure them.

Furthermore, CASBs can enforce a least privilege access control model. It allows you to create granular policy rules that determine if a user should have access to a given application.

CASB Access Implementation

You might want a developer who creates new applications using Amazon Web Services (AWS) S3 storage and DynamoDB. However, you might not want the developer to have access to the Salesforce CRM application. Because they don’t need access to it for their job.

To implement Least Privilege Access Control, then you would set up policies. Since it allows that developer only access to use S3 storage and DynamoDB, but nothing else. CASB plus Cloud Identity Provider (IdP) is integrated too.

Identity Providers are used as the source of truth for user identity data. This is for CASB solutions to enforce the least privilege access control policies across all cloud applications. For example, if you have an IdP like Ping Identity or Okta (or any other identity provider).

Then your organization can easily identify which users are accessing which cloud applications. That is through the use of the least privilege policy enforcement at the CASB layer. A Cloud Access Gateway (CA Gateway) is an optional component of a CASB solution that is used for a CASB solution to enforce policies across all cloud applications.
