Google Cloud Professional Cloud Security Engineer Practice Exam

What can be done to ensure trusted operating system images in Google Cloud projects?

1. Utilize images from any Google Cloud project

2. Limit image creation to a trusted image project only

3. Use default images provided by Google Cloud

4. Regularly review all images in the projects

The correct answer is: Limit image creation to a trusted image project only

Limiting image creation to a trusted image project is a key practice for ensuring the integrity and security of operating system images in Google Cloud projects. By designating a specific project or repository that is known and trusted—where images are maintained and monitored—you can exercise greater control over which images are allowed for use in your cloud environment. This approach mitigates the risk of unauthorized or insecure images being integrated into your systems, thereby enhancing overall security posture. Trusted image projects can be closely governed with policies and procedures to vet, approve, and regularly update images. This helps in managing vulnerabilities, ensuring compliance with security standards, and reducing the likelihood of introducing compromised images into your cloud infrastructure. The other options may appear valid at first glance, but they lack the specificity and control offered by using a dedicated trusted image project. Utilizing images from any Google Cloud project could lead to security risks, as not all projects maintain the same security and compliance standards. Default images provided by Google Cloud may be a good starting point, but they should be assessed and possibly hardened to fit your organization’s security requirements. Regularly reviewing all images is a good practice for ongoing security hygiene, but it does not prevent the initial use of untrusted images if proper image creation processes are not followed.
