Question #: 61
Topic #: 4

[All Professional Cloud Security Engineer Questions]

A company has been running their application on Compute Engine. A bug in the application allowed a malicious user to repeatedly execute a script that results in the Compute Engine instance crashing. Although the bug has been fixed, you want to get notified in case this hack re-occurs.

What should you do?

ACreate an Alerting Policy in Stackdriver using a Process Health condition, checking that the number of executions of the script remains below the desired threshold. Enable notifications.

BCreate an Alerting Policy in Stackdriver using the CPU usage metric. Set the threshold to 80% to be notified when the CPU usage goes above this 80%.

CLog every execution of the script to Stackdriver Logging. Create a User-defined metric in Stackdriver Logging on the logs, and create a Stackdriver Dashboard displaying the metric.

DLog every execution of the script to Stackdriver Logging. Configure BigQuery as a log sink, and create a BigQuery scheduled query to count the number of executions in a specific timeframe.

Suggested Answer: C

VPC Flow Logs samples each VM's TCP, UDP, ICMP, ESP, and GRE flows. Both inbound and outbound flows are sampled. These flows can be between the VM and another VM, a host in your on-premises data center, a Google service, or a host on the internet. https://cloud.google.com/vpc/docs/flow-logs

I'm no expert, but Option C seems a bit overkill. Do I really need a Stackdriver Dashboard to track a simple script execution? Option A or D sound like the simpler and more effective solutions.

I agree, Option A seems like the most direct way to monitor the script executions.

Option A sounds like a good idea. It's important to be notified if the script is executed too many times.

Option B? Really? Monitoring CPU usage to detect a script execution issue? That's like using a sledgehammer to kill a fly. Option A or D are the way to go here.

Haha, I bet the malicious user is just trying to crash the instance to get a day off work. Option A is definitely the way to go to keep an eye on that script.

I'd go with Option D. Logging the script executions to BigQuery and setting up a scheduled query to track the number of executions seems like a more robust and scalable solution.

Option D sounds like a good idea. Storing the script executions in BigQuery can help us track the number of executions.

Option A seems like the best choice here. Monitoring the process health and getting notified when the script executes more than the desired threshold is a proactive approach to detect and address the issue.
