Question 6

A security analyst is using Microsoft 365 Defender to investigate a sophisticated multi-stage attack. The analyst needs to query data across endpoints, email, and identity logs to identify the attacker's behavior patterns and correlate events. Which Microsoft 365 Defender capability should the analyst use?

Accepted Answer

Advanced hunting. Advanced hunting is the correct capability because it provides a Kusto Query Language (KQL)-based query interface that allows the security analyst to perform custom, cross-domain searches across data from endpoints (Microsoft Defender for Endpoint), email (Microsoft Defender for Office 365), and identity logs (Microsoft Defender for Identity). This enables the correlation of events and identification of attacker behavior patterns across a multi-stage attack, which is not possible with the other options.

Automated investigation and response

Answer

Threat analytics

Answer

Action center

Question 7

A company wants to reduce the attack surface on its Windows devices by blocking common techniques used by malware, such as preventing Office applications from creating child processes or blocking executable files from running from the %TEMP% folder. Which Microsoft Defender for Endpoint feature should be configured?

Accepted Answer

Attack surface reduction rules. Attack surface reduction (ASR) rules are a feature of Microsoft Defender for Endpoint that specifically target common malware behaviors, such as blocking Office applications from creating child processes and preventing executable files from running from the %TEMP% folder. These rules are designed to reduce the attack surface by enforcing policies that stop suspicious or malicious actions at the process level, without relying solely on signature-based detection.
