The answer is to ensure all data transmissions use TLS 1.2 or higher. This is the correct choice because TLS (Transport Layer Security) is the standard cryptographic protocol that encrypts data in transit, providing both confidentiality and integrity as information moves across public networks like the internet to a cloud provider. In a migration scenario, the primary risk is exposure of sensitive data while it is in motion, making TLS the most critical control to protect data in transit cloud TLS. On the Systems Security Certified Practitioner SSCP exam, this concept tests your understanding of network security fundamentals and encryption protocols, often appearing in questions about cloud security controls or secure communications. A common trap is confusing encryption at rest with encryption in transit, or accepting older versions like TLS 1.0 or SSL. Remember the memory tip: “TLS 1.2 or higher keeps the wire secure and the data pure.”
SSCP Systems and Application Security Practice Question
This SSCP practice question tests your understanding of systems and application security. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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?
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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer 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.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often 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.
Detailed technical explanation
How to think about this question
TLS 1.2 and 1.3 use a handshake to negotiate cipher suites, authenticate the server (and optionally the client) via certificates, and establish symmetric session keys for bulk encryption. In a cloud migration, data in transit is exposed to risks like man-in-the-middle attacks on public internet links; TLS ensures that even if traffic is intercepted, it cannot be decrypted without the session keys. Real-world scenarios include API calls to cloud services (e.g., AWS S3 over HTTPS) where TLS is mandatory, and failure to enforce it can lead to data leakage.

→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway

Real-world example
How this comes up in practice
A developer is choosing between AES-256 (symmetric) and RSA-2048 (asymmetric) for encrypting a large file that will be sent to a partner. Symmetric encryption is fast but requires key exchange; asymmetric is slower but solves the key distribution problem. A hybrid approach — encrypt the file with AES, encrypt the AES key with RSA — is standard. Questions like this test whether you understand when each approach applies.
