CRISC Practice Question: Based on the exhibit, which of the following…
Exhibit
Refer to the exhibit. Exhibit: ``` # show security policies policy from zone: untrust to zone: trust rule 1: source-address any, destination-address 10.0.1.0/24, application ssh, deny rule 2: source-address any, destination-address 10.0.1.5, application http, permit rule 3: source-address 192.168.2.0/24, destination-address 10.0.1.10, application mysql, permit counter: 1245 hits ```
Based on the exhibit, which of the following risks is MOST indicated by the policy configuration?
⚠ Common exam trap
The trap here is that candidates focus on the specific service (HTTP/HTTPS) and overlook the lack of encryption as the primary risk, instead considering data exfiltration or unauthorized access as more obvious threats, but the policy explicitly permits unencrypted traffic from untrusted networks.
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
✓
Exposure of web server to untrusted networks without encryption
The policy configuration shows a rule allowing inbound HTTP/HTTPS traffic from the internet to a web server without any associated encryption requirement (e.g., no TLS enforcement or VPN). This directly exposes the web server to untrusted networks, making it vulnerable to man-in-the-middle attacks and data interception, which is the most significant risk indicated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Exposure of web server to untrusted networks without encryption
Why this is correct
HTTP traffic is unencrypted and allowed from any source.
- ✗
Data exfiltration via MySQL from the internet
Why it's wrong here
MySQL only allowed from internal subnet.
- ✗
Unauthorized SSH access to the internal network
Why it's wrong here
SSH is denied from any source.
- ✗
Policy misconfiguration causing low hits on rule 3
