Question 190
At the Riverbrook professional services partnership, a private data center protects internet ingress but allows unrestricted lateral traffic between application tiers. Which explanation best accounts for the concern?
Explanation
Correct Answer
The problem stems from the fact that perimeter inspection does not monitor or restrict movement between internal workloads. A correct solution would deploy distributed or internal segmentation firewalls on application trust boundaries and check that a compromised web server cannot reach the database administration service.
Incorrect Answers
The offered principle is: Two appliances do not provide resilience when shared infrastructure remains a single point of failure. In the source material it is associated with: Two appliances do not provide resilience when shared infrastructure remains a single point of failure. This case has a different controlling cause: Perimeter inspection does not monitor or restrict movement between internal workloads. Its keyed mechanism is: Perimeter inspection does not monitor or restrict movement between internal workloads.
The offered principle is: Authentication success cannot compensate for missing routing to remote client addresses. In the source material it is associated with: Authentication success cannot compensate for missing routing to remote client addresses. This case has a different controlling cause: Perimeter inspection does not monitor or restrict movement between internal workloads. Its keyed mechanism is: Perimeter inspection does not monitor or restrict movement between internal workloads.
Time injection can corrupt security-event sequence and certificate checks. That may occur elsewhere, but the evidence at the Riverbrook professional services partnership instead points to the fact that perimeter inspection does not monitor or restrict movement between internal workloads.
