What practice aids incident responders in eradicating Google Cloud security incidents?

The correct answer highlights the importance of securing storage buckets within Google Cloud to prevent unauthorized access, which is crucial for incident response. By ensuring that storage buckets are not publicly accessible, organizations can significantly reduce the risk of data breaches and exploits that may stem from vulnerabilities in these storage containers.

When storage buckets are left open to public access, they can be scanned and targeted by malicious actors, leading to unauthorized data retrieval or manipulation. For incident responders, the primary focus is to minimize exposure to security incidents, and restricting access to storage buckets is an effective way to mitigate potential threats.

In contrast, practices such as ensuring public access or disabling account activity alerts can actually increase vulnerabilities rather than mitigate them, while implementing data encryption, while important, does not specifically address the immediate risk posed by publicly accessible resources. A comprehensive security approach must prioritize access controls, thus reinforcing the rationale for ensuring that storage buckets are not publicly accessible.
