In Azure Security Center (now Microsoft Defender for Cloud) , different roles have different levels of permission. To meet the principle of least privilege , you must assign only the minimal role required for each action.

Enable and disable Azure Defender

Enabling or disabling Microsoft Defender plans (formerly Azure Defender) changes billing and protection settings at the subscription level .

According to Microsoft documentation:

“Only users with the Subscription Owner or Security Admin roles at the subscription level can enable or disable Microsoft Defender plans.”

Because this change affects billing and overall subscription configuration, the Subscription Owner role is the appropriate one — it has full control at the subscription scope.

Apply security recommendations to a resource

Applying recommendations (such as enabling disk encryption or updating system patches) involves managing configuration settings on specific resources.

The Resource Group Owner role provides full management access to all resources within that resource group, which includes the ability to implement or re mediate recommendations.

Microsoft Defender for Cloud guidance states:

“To apply recommendations or perform remediation tasks on specific resources, the user must have write permissions on those resources — typically provided by the Resource Group Owner or Contributor role.”

✅ Final Correct Mapping:

Enable and disable Azure Defender → Subscription Owner

Apply security recommendations to a resource → Resource Group Owner

When configuring the Syslog via Azure Monitor Agent (AMA) connector in Microsoft Sentinel , the Data Collection R ule (DCR) determines which Linux system logs are ingested. Syslog messages are filtered based on facility (the subsystem that generated the message) and severity level (priority) .

According to Microsoft’s “Collect Syslog data sources using Azure Monitor Ag ent” documentation:

“Syslog facilities define which type of process generated the log (e.g., authentication, cron, daemon), and log levels define the severity (0=emerg, 1=alert, 2=crit, 3=err, etc.). To minimize data ingestion and cost, select only the fac ility and the highest severity level required for your investigation.”

In this scenario:

You need to collect logs related to App1 , a background process (non-kernel, non-authentication, non-cron). Typically, such custom or application-level processes send logs to LOG_AUTH or LOG_DAEMON , depending on configuration. If App1 is an application that uses authentication or security features, the LOG_AUTH facility is appropriate.

You must collect only logs with a critical priority , which corresponds to Syslog severity 2 (critical) . In Syslog terminology, that maps to the LOG_EMERG or “emergency” level and above.

However, to ensure minimum data collection while still capturing critical events, Sentinel’s best practice is to configure the Syslog DCR to collect on ly the specific facility associated with the application and the exact required severity level. For “critical only,” LOG_EMERG is the correct choice because it ensures that only the most urgent (critical/emergency) events are ingested, reducing data volume and cost.

✅ Final Configuration:

Setting

Correct Option

Purpose

Facility

LOG_AUTH

Collects security/authentication-related logs for App1

Log level

LOG_EMERG

Collects only critical/emergency events (priority ≤ 0) to minimize ingestion volume

In summary:

Selecting LOG_AUTH and LOG_EMERG satisfies both requirements — capturing only the highest-severity logs relevant to App1 while keeping the ingestion volume minimal, in line with Microsoft Sentinel Syslog DCR configuration guidance.

In Microsoft Sentinel’s Advanced Security Information Model (ASI M) , DNS queries are normalized through the Im_Dns parser, which unifies DNS telemetry from multiple sources (Infoblox, Windows DNS, Azure Firewall DNS proxy, etc.). Microsoft guidance states that when you need broad compatibility and want to “use built-in ASIM parsers whenever possible,” you should call the generic Im_Dns() parser . To minimize overhead , ASIM provides a pack parameter that restricts the parser to a specific content pack (vendor/source) so it won’t iterate through all available source parsers under the hood. For Infoblox NIOS, you pass the Infoblox pack via the pack parameter, which limits parsing to the Infoblox implementation and reduces query cost/latency while keeping the query portable across environments.

Putting it together, the recomme nded pattern is:

Im_Dns(pack= " InfobloxNIOS " )

| where DnsResponseCodeName == " NXDOMAIN "

| summarize count()

This approach satisfies all requirements:

Uses built-in ASIM (Im_Dns).

Minimizes query overhead (uses pack to limit parsing to Infoblox).

Targets NXD OMAIN responses for counting DNS request failures from Infoblox1 .
