Answer : B

To pivot within a row to Causality view and Timeline views for further investigation, you can use the Open Card and Open Timeline actions respectively. The Open Card action will open a new tab with the Causality view of the selected row, showing the causal chain of events that led to the alert. The Open Timeline action will open a new tab with the Timeline view of the selected row, showing the chronological sequence of events that occurred on the affected endpoint. These actions allow you to drill down into the details of each alert and understand the root cause and impact of the incident.Reference:

Answer : A

The Windows Registry is a hierarchical database that stores settings for the operating system and for applications that run on Windows. The registry contains information, settings, options, and other values for programs and hardware installed on all versions of Microsoft Windows operating systems. The registry is organized into five main sections, called hives, each of which contains keys, subkeys, and values. The Cortex XDR agent uses the registry to store its configuration, status, and logs, as well as to monitor and control the endpoint's security features. The Cortex XDR agent also allows you to run scripts that can read, write, or delete registry keys and values on the endpoint.Reference:

Registry Operations

Answer : C

The best action to delete the file on the Linux endpoint is to initiate Remediation Suggestions from the Cortex XDR console. Remediation Suggestions are a feature of Cortex XDR that provide you with recommended actions to undo the effects of malicious activity on your endpoints. You can view the remediation suggestions for each alert or incident in the Cortex XDR console, and decide whether to apply them or not. Remediation Suggestions can help you restore the endpoint to its original state, remove malicious files or processes, or fix registry or system settings. Remediation Suggestions are based on the forensic data collected by the Cortex XDR agent and the analysis performed by Cortex XDR.

The other options are incorrect for the following reasons:

A is incorrect because manually remediating the problem on the endpoint is not a convenient or efficient way to delete the file. Manually remediating the problem would require you to access the endpoint directly, log in as root, locate the file, and delete it. This would also require you to have the necessary permissions and credentials to access the endpoint, and to know the exact path and name of the file. Manually remediating the problem would also not provide you with any audit trail or confirmation of the deletion.

B is incorrect because opening X2go from the Cortex XDR console is not a supported or secure way to delete the file. X2go is a third-party remote desktop software that allows you to access Linux endpoints from a graphical user interface. However, X2go is not integrated with Cortex XDR, and using it would require you to install and configure it on both the Cortex XDR console and the endpoint. Using X2go would also expose the endpoint to potential network attacks or unauthorized access, and would not provide you with any audit trail or confirmation of the deletion.

D is incorrect because opening an NFS connection from the Cortex XDR console is not a feasible or reliable way to delete the file. NFS is a network file system protocol that allows you to access files on remote servers as if they were local. However, NFS is not integrated with Cortex XDR, and using it would require you to set up and maintain an NFS server and client on both the Cortex XDR console and the endpoint. Using NFS would also depend on the network availability and performance, and would not provide you with any audit trail or confirmation of the deletion.

Answer : C

WildFire is a cloud-based service that accepts and analyses samples from various sources, including Cortex XDR, to provide a verdict of malware, benign, or grayware. WildFire also generates detailed analysis reports that show the behaviour and characteristics of the samples. Cortex XDR uses WildFire verdicts and reports to enhance its detection and prevention capabilities, as well as to provide more visibility and context into the threats.Reference:

Answer : D

To add an exception to exclude a specific file hash from examination by the Malware profile for a Windows endpoint, you need to use the Action Center in Cortex XDR. The Action Center allows you to create and manage actions that apply to endpoints, such as adding files or processes to the allow list or block list, isolating or unisolating endpoints, or initiating live terminal sessions. To add a file hash to the allow list, you need to choose Allow list, select new action, select add to allow list, add your hash to the list, and apply it.This will prevent the Malware profile from scanning or blocking the file on the endpoints that match the scope of the action.Reference: Cortex XDR 3: Responding to Attacks1, Action Center2
