What are the CASBs?

Cloud Access Security Brokers (CASBs) are tools that act as security guards between people using cloud services and the companies providing those services. They make sure a company’s security rules are applied to their cloud activities. This is very important as more businesses use cloud technology for different tasks and storing data, which comes with various security risks and rules to follow.

CASBs have four main roles: visibility, data security, threat protection, and compliance. The visibility function lets companies see who is using what applications, which helps them control access to only approved cloud services and avoid risky ones. For data security, CASBs provide methods to keep sensitive information secure from unauthorized access and leaks, often using encryption or other protective measures. In terms of threat protection, they actively detect and deal with malware and other online threats. Lastly, they ensure that data in the cloud follows legal and regulatory standards, like GDPR for privacy or HIPAA for health information.

By acting as middlemen between cloud users and cloud services, Cloud Access Security Brokers (CASBs) help organizations apply their security rules not just within their own systems, but also across their cloud activities. This ensures that their security standards are uniform everywhere. This basic idea prepares us to look more closely at how to properly assess and manage these important security tools.
