Question

Your organization runs workloads in Google Cloud and already uses Security Command Center (SCC) Premium for misconfiguration and vulnerability findings. A compliance auditor questions why the security team also proposes deploying Cloud IDS, arguing that it appears redundant with SCC's threat detection capabilities. As the Security Operations Engineer, what is the strongest justification for maintaining both tools rather than eliminating one to reduce cost?

Accepted Answer

SCC evaluates cloud resource posture and surfaces configuration and vulnerability risks, while Cloud IDS performs deep packet inspection of network traffic to detect active exploits, malware, and command-and-control — providing complementary posture and network-layer coverage.

Answer

Cloud IDS fully replaces SCC's Event Threat Detection, so SCC should be downgraded to Standard tier once Cloud IDS is deployed to avoid paying for duplicate threat detection.

Answer

SCC and Cloud IDS both analyze the same VPC flow logs, so keeping both simply doubles the alerting confidence through voting-based correlation.

Answer

Cloud IDS provides IAM misconfiguration scanning that SCC lacks, making it the primary posture management tool while SCC handles only network inspection.
