CAS-004 Practice Question: Protect its intellectual property stored on a…
A company wants to protect its intellectual property stored on a file server. The security architect proposes implementing rights management services (RMS) integrated with Active Directory. Which attack is this architecture primarily designed to mitigate?
⚠ Common exam trap
Many exam-takers confuse data-at-rest protection (e.g., file server encryption) with data-in-use protection (RMS), leading them to incorrectly select malware or buffer overflow options, which are server-level threats rather than content-level distribution threats.

Correct answer & explanation
✓
Unauthorized distribution of sensitive documents outside the organization
Rights Management Services (RMS) integrated with Active Directory enables persistent protection of documents by encrypting them and enforcing usage policies (e.g., who can open, print, or forward) regardless of where the file resides. This architecture is specifically designed to prevent unauthorized distribution of sensitive documents outside the organization because the protection travels with the file and requires authentication to an RMS server for decryption, even if the file is copied or emailed externally.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Unauthorized distribution of sensitive documents outside the organization
Why this is correct
RMS restricts access and usage rights even after documents leave the server.
- ✗
Phishing attacks targeting user credentials
Why it's wrong here
RMS does not prevent credential theft.
- ✗
Malware infection on the file server
Why it's wrong here
RMS does not protect the server from malware; it protects the data itself.
- ✗
Buffer overflow attack on the file server
Why it's wrong here
RMS does not prevent exploitation of server vulnerabilities.
