Question 680
Following a security operations retrospective at a global consulting firm, the service owner has to defend a design against oversimplified assumptions. The requirement is: A SOC has created a Sentinel workspace but sees no authentication events from its identity system. The review is limited to the control and concept described by this requirement. Which unsupported assumption would MOST directly undermine this requirement?
- Assuming an empty workspace automatically collects every cloud tenant's logs without connectors.
- Assuming Defender XDR is only a single antivirus engine and cannot correlate supported security domains.
- Assuming private networking removes the need to control which identities may read the data.
- Assuming endpoint antivirus signatures prove every installed application is fully patched.
Explanation
Correct Answer
A:Assuming an empty workspace automatically collects every cloud tenant's logs without connectors. This belief conflicts with this control principle: Analytics depends on correct telemetry ingestion before correlation or hunting can work. The appropriate response instead is: Configure and validate the appropriate Sentinel data connector and required source permissions.
