Discuss Google Professional Cloud Security Engineer Exam Topic 4 Question 6

You are on your company's development team. You noticed that your web application hosted in staging on GKE dynamically includes user data in web pages without first properly validating the inputted data. This could allow an attacker to execute gibberish commands and display arbitrary content in a victim user's browser in a production environment.

How should you prevent and fix this vulnerability?

AUse Cloud IAP based on IP address or end-user device attributes to prevent and fix the vulnerability.

BSet up an HTTPS load balancer, and then use Cloud Armor for the production environment to prevent the potential XSS attack.

CUse Web Security Scanner to validate the usage of an outdated library in the code, and then use a secured version of the included library.

DUse Web Security Scanner in staging to simulate an XSS injection attack, and then use a templating system that supports contextual auto-escaping.

Suggested Answer: D

Wait, can an attacker really execute commands like that? Sounds wild!

I agree, HTTPS and Cloud Armor should be a priority!

Not sure if Cloud IAP is enough for this kind of vulnerability.

I think using a templating system is the best way to go!

Definitely need to validate user input to avoid XSS.

I feel like the Web Security Scanner is crucial here, especially in staging. We definitely need to simulate those attacks to identify vulnerabilities.

I think using a templating system that supports auto-escaping sounds familiar. We practiced something similar in our last session, right?

I remember we discussed the importance of validating user input to prevent XSS attacks, but I'm not sure which option directly addresses that.

I’m a bit confused about the role of Cloud Armor. Does it really help with XSS, or is it more for DDoS protection?

I'm a little confused by the wording of the question. Do we need to consider the length of the cables as well? Maybe option C is worth considering to allow for flexibility.

Payroll fraud is a tricky topic, but I'm going to go with C - Planning as my best guess.

I feel pretty confident about this one. The key is to create a separate portal for the external researchers to collaborate, while giving the internal staff access to the main org. That way, we're meeting the needs of both groups.

This looks like a tricky question. I'll need to think carefully about the different methods and how they use the product search index.
