Google Professional Cloud Security Engineer Exam - Topic 4 Question 61 Discussion

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?
C) Log 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.
A) Create 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.
B) Create 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%.
D) Log 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.

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

Wait, can a script really crash an entire instance? That's wild!

C is interesting, but isn't it overkill for just tracking a single script?

I disagree, B is too generic. CPU spikes don't directly indicate the script issue.

Option D seems like it could work too, especially with BigQuery for analysis, but I wonder if it's overkill for just monitoring script executions.

I like option C because logging every execution seems like a good way to track the script, but I'm not sure how to set up the user-defined metric.

I remember practicing with Stackdriver alerts, but I feel like using CPU usage like in option B might not directly address the script execution problem.

I think option A sounds familiar, but I'm not entirely sure if a Process Health condition is the right way to go for this specific issue.

I'm a bit confused here. Wouldn't setting the cart to use a custom URL, option A, also help resolve the problem? That seems like a viable alternative to the Redis solution.

Okay, let me think this through. A reduction in reserves is bad, so it must be an "unfavorable development." And an increase is good, so it's an "advance development." I think I've got it!

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.

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.

True, but logging to BigQuery gives us more flexibility in analyzing the data and setting up custom queries.
