SASE converges network and security capabilities to provide deep visibility, consistent security, and granular controls across the entire hybrid network.
That's a lot of functionality, and confusion persists about what each element does as an independent technology and as a part of SASE. In this piece, I'll discuss the importance of CASB and examine its role within SASE, particularly why it's critical to the solution's success.
Moving sensitive data to and from SaaS applications increases the risk of a breach and extends an organization's attack surface.
CASBs have emerged as a solution to this challenge because they provide deep visibility into cloud and SaaS deployments, allowing IT teams to protect users and sensitive corporate data in these environments.
As a part of SASE, CASBs handle cloud security risks and support work-from-anywhere employees who use personal, unmanaged devices to access SaaS applications from new, disparate locations.
CASBs help ensure compliance with data and privacy regulations.
CASBs fill this gap through features such as access control, collaboration control, DLP, encryption, information rights management, and tokenization.
Threat protection: A CASB solution helps organizations protect against insider attacks from authorized users by creating a regular usage pattern baseline.
Using machine learning, CASBs can quickly detect unusual or nefarious user activity.
Assess risk - CASB evaluates application usage, especially inconsistent spikes, to determine risk and ensure that corporate data is handled safely.
Address compliance - CASB reports on using frameworks such as SOX, GDPR, PCI DSS, HIPAA, NIST, and ISO 27001 to identify policy violations for remediation.
Prevent data loss - With a highly customizable suite of DLP tools and predefined compliance reports, CASB helps defend against data breaches.
Malware protection - CASB quarantines suspicious files and blocks malware from uploading or downloading via SaaS applications.
Secure non-corporate tenants - By employing a user list that specifies non-corporate tenant restrictions, a CASB can control access from managed and unmanaged locations.
Illuminate shadow IT - To help enforce policy-based access controls, CASBs provide administrators with usage information for all sanctioned and unsanctioned cloud applications.
The main purpose of CASB within an organization's SASE solution is to extend and manage security policies for data housed in cloud-based services.
Since many organizations have adopted hybrid-cloud strategies and deployed SaaS applications, such as Salesforce.com and Office 365, they need to see and control the data stored outside the traditional IT edges.
If organizations have large shadow IT programs or permit internal groups to buy and manage cloud-based services without IT expert involvement, CASBs can be a critical tool for discovery and management.
The insights provided by a CASB solution can help an IT organization gain better visibility into cloud-based applications being used and where confidential and proprietary data is stored.
