SSCP Practice Question: Ensure that data transmitted between its two…
A company wants to ensure that data transmitted between its two branch offices remains confidential. Which cryptographic goal is primarily being addressed?
⚠ Common exam trap
Test-takers frequently confuse confidentiality with integrity, mistakenly thinking that protecting data from modification also prevents it from being read, but encryption alone does not guarantee integrity unless combined with a MAC or authenticated encryption mode like GCM.
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
✓
Confidentiality
Confidentiality ensures that data is accessible only to authorized parties, typically achieved through encryption. In this scenario, the company wants to prevent unauthorized interception of data between branch offices, which is the core goal of confidentiality. Technologies such as IPsec VPNs or TLS are used to encrypt the data in transit, directly addressing this requirement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Availability
Why it's wrong here
Availability ensures systems are accessible, not confidentiality.
- ✗
Non-repudiation
Why it's wrong here
Non-repudiation prevents denial of actions, not confidentiality.
- ✗
Integrity
Why it's wrong here
Integrity ensures data has not been altered, not confidentiality.
- ✓
Confidentiality
Why this is correct
Confidentiality is the goal of keeping data secret, achieved via encryption.
Quick reference
VPN Protocol Comparison
| Protocol | Port | Encryption | Authentication | Use Case |
|---|---|---|---|---|
| IKEv2 / IPsec | UDP 500 / 4500 | AES-256 | Certificates / PSK | Site-to-site & remote access |
| SSL / TLS VPN | TCP 443 | TLS 1.3 | Certificates / MFA | Clientless remote access |
| L2TP / IPsec | UDP 1701 | AES (IPsec) | PSK / Certificates | Legacy remote access |
| WireGuard | UDP 51820 | ChaCha20 | Public keys | Modern high-performance VPN |
| PPTP | TCP 1723 | MPPE (weak) | MS-CHAPv2 | Legacy — avoid in production |
PPTP is considered insecure. IKEv2/IPsec and SSL VPN are the current recommended options.
