Why Are CASBs Important?
A CASB is a gatekeeper that helps organizations monitor and safely use cloud services, while ensuring that network traffic complies with that organization’s security policies and regulations. With these extraordinary tools in place to safeguard data, cloud application-use across various platforms is visible to consumers. In addition, those actors who pose a threat are identified, so that the threat of security violation can be stopped in its tracks.
How Do CASBs Work?
CASBs use auto-discovery to identify the cloud applications that are in use as well as the various risk factors that could impact an organization. Designed to be vigilant as well as proactive, they protect organizations via firewalls, authentication, and data loss prevention.
What Kinds of Security Policies Can CASBs Enforce?
Examples of security policies that they can enforce include:
1. Authentication
2. Single sign on
3. Authorization
4. Alerting
5. Ability to see authorized and unauthorized cloud usage
6. Credential mapping
7. Device profiling
8. Encryption
9. Tokenization
10. Logging
11. Malware detection/prevention
The Future of CASBs
Cloud service providers currently run extremely secure operations. As a matter of fact, most security failures are caused by customer security errors and not by cloud service provider security issues. As a result, according to the extensive research done in 2018 by Gartner®, 60 percent of large enterprises are predicted to choose a CASB as the primary protector of their data within the next three years.
With the assurance of a successful future for cloud service security, there is no reason for customers to be nervous about using the cloud for their data. In fact, with CASBs, the most comprehensive threat assessment, protection and remediation are now available, elevating cloud usage to new heights, and enabling it to be the most secure way an organization can handle its data.
