The problem described in the case study states that “Cloud App Security frequently generates false positive alerts when users connect to both offices simultaneously.” This behavior is commonly associated with the “Impossible travel” anomaly detection policy in Microsoft Defender for Cloud Apps .

According to Microsoft documentation, the “Impossible travel” policy detects when a user signs in from two locations that are geographically dis tant within an unrealistic timeframe. However, in multi-office environments (such as Boston and Seattle) or when VPN connections are used, this policy can frequently trigger false positives , since it may misinterpret legitimate connections as anomalous.

Mi crosoft recommends adjusting the impossible travel detection policy to account for trusted IP ranges, known locations, or VPN endpoints to reduce false alerts. Specifically, administrators can modify the policy’s sensitivity, include the organization’s off ice IP addresses as trusted, and exclude known network ranges.

This approach directly aligns with the case study’s scenario and satisfies the Defender for Cloud Apps requirement to reduce false positives while maintaining user anomaly detection accuracy.

According to Microsoft Defender for Cloud (formerly Azure Security Center) documentation, when integrating servers and virtual machines for security monitoring, the Defender for Cloud data is stored and analyzed in a Log Analytics workspace . Microsoft best practices recommend using an existing workspace when one is already deployed for centralized log collection—especially if it already gathers telemetry from Azure and on-premises resources.

In this case, the existing workspace LA1 already “contains logs and metrics collected from all Azure resources and on-premises servers.” This satisfies the business requirement of “all servers must send logs to the same Log Analytics workspace.” Creating a new workspace would violate the cost-min imization and centralization requirements. Therefore, LA1 is the correct workspace to use.

For the Windows security events collection setting, Defender for Cloud offers three levels:

Minimal – collects essential security events only (insufficient for compr ehensive monitoring).

Common – collects a balanced set of security-related events (such as account logon, privilege use, and object access), recommended by Microsoft for most environments.

All Events – collects every possible security event, which increase s data ingestion cost and is typically used only for high-security or regulated environments.

Because Litware Inc. must minimize cost while ensuring a full audit trail of user activities , the Common level provides the optimal balance of visibility and cost efficiency.

Therefore, based on Microsoft Defender for Cloud configuration guidelines:

✅ Log Analytics workspace to use: LA1

✅ Windows security events to collect: Common

When creating scheduled analytics rules in Microsoft Sentinel, you should account for ingestion delay so late-arriving events aren’t missed, while also avoiding reprocessing the same events. The recommended pattern is to widen the TimeGenerated w indow by the expected delay and then gate results by ingestion_time() to include only data that actually arrived within the delay window:

let ingestion_delay = 5min;

let rule_look_back = 7min;

CommonSecurityLog

| where TimeGenerated > = ago(ingestion_delay + rule_look_back) // cover late arrivals

| where ingestion_time() > ago(ingestion_delay) // only newly ingested data

TimeGenerated > = ago(ingestion_delay + rule_look_back) ensures the query looks back 7 + 5 = 12 minutes , so events that were generated up to 7 minutes ago but arrived up to 5 minutes late are still captured.

ingestion_time() > ago(ingestion_delay) limits results to items ingested in the last 5 minutes , preventing the same already-processed events from being picked up again on the next run, while minimizing misses due to late ingestion.

Thus, choose (ingestion_delay + rule_look_back) for the first blank and (ingestion_delay) for the second.
