Question 361 · 392 in bank
You have a Microsoft 365 subscription that contains a user named User1 and two Windows devices named Device1 and Device2. Device1 and Device2 are onboarded to Microsoft Defender for Endpoint. The following events occur. • User1 signs in to Device1. • Automatic attack disruption in Microsoft Defender XDR responds to an attack on Device1 and contains User1. • User1 attempts to connect to Device2. Which protocols will Device2 block when User1 attempts to connect to Device2?
Show answer
Answer: F
Explanation
When Automatic Attack Disruption in Microsoft Defender XDR contains a user due to an identified attack, it takes specific actions to isolate the user and prevent the spread of the attack. One of these actions is blocking specific protocols to limit lateral movement and access to other devices. For User1, attempting to connect to another device (Device2) after being contained will result in blocking access via the following protocols: RDP (Remote Desktop Protocol): Commonly used for remote management and often exploited in lateral movement attacks. RPC (Remote Procedure Call): Used for remote execution of tasks and communication between Windows systems; also a common target for attackers. SMB (Server Message Block): Facilitates file sharing and other operations between devices. Attackers frequently exploit SMB vulnerabilities for lateral movement and data exfiltration.
