SSCP Practice Question: Migrating its on-premises applications to a…
A company is migrating its on-premises applications to a public cloud. Which security control is MOST important to implement to protect data in transit?
⚠ Common exam trap
Many candidates confuse IPsec VPNs (which protect network-layer traffic) with the application-layer encryption provided by TLS, assuming VPNs are always superior for cloud connections, but TLS is the standard and most practical control for protecting data in transit to public cloud services.

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
✓
Ensure all data transmissions use TLS 1.2 or higher.
TLS 1.2 or higher is the standard protocol for encrypting data in transit over public networks, ensuring confidentiality and integrity between client and server. It is the most critical control because it directly protects data as it moves across the internet to the cloud, which is the primary risk in a migration scenario.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable server-side encryption for cloud storage.
Why it's wrong here
Protects data at rest, not in transit.
- ✗
Implement data classification labels.
Why it's wrong here
Data classification helps with handling but does not protect data in transit.
- ✗
Use IPsec VPNs for all cloud connections.
Why it's wrong here
IPsec is one option but not always necessary; TLS is more common for web traffic.
- ✓
Ensure all data transmissions use TLS 1.2 or higher.
Why this is correct
TLS encrypts data in transit and is widely supported.
