CCSP Practice Question: A security team is implementing Data Loss…
A security team is implementing Data Loss Prevention (DLP) for a SaaS application that stores customer PII. They want to detect when sensitive data is shared externally via email. Which is the best approach?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use the SaaS application's API DLP rules to scan email content and attachments
SaaS application API DLP rules can inspect email content and attachments directly within the application, effectively detecting sensitive data shared externally via email. Option A is wrong because database DLP monitors queries to the database, not email communications. Option B is wrong because endpoint DLP agents on user devices may not be able to inspect cloud-based email traffic that is accessed via browser. Option D is wrong because network DLP at the cloud provider's perimeter cannot inspect encrypted email traffic (e.g., TLS) and is less effective for SaaS-based email.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Implement database DLP to monitor queries to the PII database
Why it's wrong here
Database DLP inspects queries and result sets inside the PII store, so it cannot see data once it leaves the database and travels through the SaaS email channel. Database activity monitoring is the right control for detecting anomalous or bulk access to stored records, not outbound sharing.
- ✗
Install endpoint DLP agents on all user devices
Why it's wrong here
Endpoint agents only inspect activity on managed devices they are installed on; email sent from unmanaged devices, mobile clients, or the SaaS web interface bypasses them entirely. Endpoint DLP suits controlling data on corporate laptops and removable media, not server-side SaaS email egress.
- ✓
Use the SaaS application's API DLP rules to scan email content and attachments
Why this is correct
API-based DLP inspects email content and attachments directly within the SaaS platform, catching external shares regardless of endpoint or transport. This satisfies the constraint of detecting sensitive PII leaving via the application's own email channel.
- ✗
Deploy network DLP at the cloud provider's network perimeter
Why it's wrong here
Network DLP at the provider perimeter cannot inspect TLS-encrypted SaaS email traffic or content within the provider's own service boundary. Perimeter inspection suits unencrypted egress from your own network, whereas SaaS email requires API-based or CASB-integrated content inspection.
