Enforces compliance: An Intune connection To enforce compliance using Microsoft Defender for Endpoint risk signals within a Conditional Access policy, you must first establish a service-to-service connection between Microsoft Intune and Microsoft Defender for Endpoint. This connection allows Defender to send device risk data to Intune. Intune then uses this data in a device compliance policy to mark devices as compliant or non-compliant. Finally, Conditional Access policies can leverage this compliance status to grant or block access to corporate resources, thereby enforcing compliance based on the device's threat level. Prevents suspicious scripts: An attack surface reduction (ASR) rule Attack surface reduction (ASR) rules are a component of Microsoft Defender for Endpoint designed to mitigate actions and application behaviors commonly used by malware. The specific ASR rule, "Block execution of potentially obfuscated scripts," directly addresses the requirement to prevent suspicious scripts. When enabled, this rule analyzes scripts and blocks those that appear to be intentionally obscured, a common technique used by attackers to hide malicious code. These rules are configured within Intune under the Endpoint security workload. Incorrect Options: A device restriction policy: While these Intune policies configure a wide variety of device settings, they are a general mechanism. ASR rules are the specific feature designed to block behaviors like suspicious scripts and are typically managed in a dedicated Attack Surface Reduction policy within Intune's Endpoint security section. A security baseline: This is a pre-configured group of recommended security settings (which can include ASR rules). However, the baseline itself is a deployment template, not the underlying feature that performs the action. The feature that actively prevents the script is the ASR rule itself.

Intune" sections explicitly state that the first step is to set up the service-to-service

connection. The "Workflow" diagram on the page illustrates this dependency.

Reference: The table of ASR rules lists the rule "Block execution of potentially obfuscated

scripts" and describes its function as detecting and blocking scripts that appear obfuscated.

explains that these policies are used to manage ASR rules on devices. This distinguishes

ASR policy from general device restriction policies.
