Question 80:

Which Google Cloud service provides centralized security management and threat detection across Google Cloud resources?

A) Cloud Armor
B) Security Command Center
C) Cloud Identity
D) Cloud KMS

Answer: B ) Security Command Center

Explanation:

Security Command Center (SCC) is Google Cloud’s centralized security and risk management platform that provides organizations with comprehensive visibility and control over their cloud security posture. SCC helps enterprises identify vulnerabilities, misconfigurations, exposed sensitive data, and potential threats across Google Cloud resources. It integrates with Cloud IAM, Cloud Logging, VPC Flow Logs, Cloud Asset Inventory, and third-party security tools to provide a unified view of security risks, allowing security teams to detect, prioritize, and remediate threats effectively.

SCC continuously monitors cloud resources and provides automated threat detection, vulnerability management, and security insights. It categorizes findings by severity and impact, helping teams prioritize actions and maintain compliance with regulatory requirements such as GDPR, HIPAA, and PCI DSS. Security Command Center enables proactive management of risks by alerting administrators to anomalies, misconfigured resources, exposed storage buckets, or unusual account activity. It also integrates with Cloud Logging and Cloud Monitoring to allow correlation of security events with operational metrics for more informed decision-making.

Operationally, SCC reduces the burden on security teams by consolidating visibility, automating detection, and enabling centralized remediation workflows. Real-world use cases include monitoring sensitive data access, auditing user activity, preventing misconfiguration-induced vulnerabilities, and mitigating threats in multi-project or multi-region cloud environments. SCC provides a foundation for enterprises to maintain security governance, perform compliance audits, and respond quickly to incidents without manually inspecting each resource or system.
