The Zscaler SaaS Security API is designed to scan sanctioned SaaS applications for sensitive data at rest and remediate policy violations. A Data Loss Prevention (DLP) rule within this service identifies files containing sensitive information (e.g., PII, financial data). A primary risk is the overexposure of this data through improper sharing. A valid and common remediation action for a DLP violation is to automatically remove external collaborators' access to the file and delete any publicly accessible sharing links, thereby containing the data and preventing loss.

A. Enable AI/ML based Smart Browser Isolation: This is an action associated with Zscaler Internet Access (ZIA) for controlling real-time web traffic and isolating user browsing sessions, not for remediating data at rest found by the SaaS Security API.

B. Quarantine Malware: This is a valid action within the SaaS Security API platform, but it is specifically for a Malware Detection policy, not a Data Loss Prevention (DLP) policy, which is triggered by data content, not malicious code.

C. Create Zero Trust Network Decoy: This is a function of Zscaler's deception technology, used to detect active threats within a network by luring attackers. It is not a remediation action for a DLP policy violation in a SaaS application.

"Configuring the SaaS Security API DLP Policy": This official documentation outlines the specific actions available for DLP rules. Under the "Add DLP Rule" section

the available remediation actions include "Remove Publicly Sharable Links" and "Remove Collaborators

" which directly supports the correct answer (D). It also lists "Quarantine" as an action for the file itself

but distinguishes this from malware-specific actions.

2. Zscaler Help Portal

"About SaaS Security API": This document provides an overview of the service

stating its purpose is to "scan your SaaS applications for data loss

threats

and compliance violations." It emphasizes control over data at rest

which aligns with the remediation action of managing sharing permissions.

3. Zscaler Help Portal

"Configuring the SaaS Security API Malware Detection Policy": This document details the actions for malware detection

which include "Quarantine" and "Delete." This confirms that "Quarantine Malware" (Option B) is an action tied to a different policy type than the one specified in the question (DLP).
