Paloalto Networks XDR-Analyst Dumps Questions Answers

 The correct answer is B, the level of risk is assigned to the script upon import. When you import a script to the Agent Script Library in Cortex XDR, you need to specify the level of risk associated with the script. The level of risk determines the permissions and restrictions for running the script on endpoints. The levels of risk are:

Low: The script can be run on any endpoint without requiring approval from the Cortex XDR administrator. The script can also be used in remediation suggestions or automation actions.

Medium: The script can be run on any endpoint, but requires approval from the Cortex XDR administrator. The script can also be used in remediation suggestions or automation actions.

High: The script can only be run on isolated endpoints, and requires approval from the Cortex XDR administrator. The script cannot be used in remediation suggestions or automation actions.

The other options are incorrect for the following reasons:

A is incorrect because not any version of Python script can be run in Cortex XDR. The scripts must be written in Python 2.7, and must follow the guidelines and limitations described in the Cortex XDR documentation. For example, the scripts must not exceed 64 KB in size, must not use external libraries or modules, and must not contain malicious or harmful code.

C is incorrect because not any script can be imported to Cortex XDR, including Visual Basic (VB) scripts. The scripts must be written in Python 2.7, and must follow the guidelines and limitations described in the Cortex XDR documentation. VB scripts are not supported by Cortex XDR, and will not run on the endpoints.

D is incorrect because the script is not run on the machine uploading the script to ensure that it is operational. The script is only validated for syntax errors and size limitations when it is imported to the Agent Script Library. The script is not executed or tested on the machine uploading the script, and the script may still fail or cause errors when it is run on the endpoints.

The report output shows the number of endpoints that have forensic inventory data collection enabled, which is a feature of Cortex XDR that allows the collection of detailed information about the endpoint’s hardware, software, and network configuration. This feature helps analysts to investigate and respond to incidents more effectively by providing a comprehensive view of the endpoint’s state and activity. Forensic inventory data collection can be enabled or disabled per policy in Cortex XDR. References:

Cortex XDR 3: Getting Started with Endpoint Protection

An example of an attack vector for ransomware is phishing emails containing malicious attachments. Phishing is a technique that involves sending fraudulent emails that appear to come from a legitimate source, such as a bank, a company, or a government agency. The emails typically contain a malicious attachment, such as a PDF document, a ZIP archive, or a Microsoft Office document, that contains ransomware or a ransomware downloader. When the recipient opens or downloads the attachment, the ransomware is executed and encrypts the files or data on the victim’s system. The attacker then demands a ransom for the decryption key, usually in cryptocurrency.

Phishing emails are one of the most common and effective ways of delivering ransomware, as they can bypass security measures such as firewalls, antivirus software, or URL filtering. Phishing emails can also exploit the human factor, as they can trick the recipient into opening the attachment by using social engineering techniques, such as impersonating a trusted sender, creating a sense of urgency, or appealing to curiosity or greed. Phishing emails can also target specific individuals or organizations, such as executives, employees, or customers, in a technique called spear phishing, which increases the chances of success.

According to various sources, phishing emails are the main vector of ransomware attacks, accounting for more than 90% of all ransomware infections12. Some of the most notorious ransomware campaigns, such as CryptoLocker, Locky, and WannaCry, have used phishing emails as their primary delivery method3 . Therefore, it is essential to educate users on how to recognize and avoid phishing emails, as well as to implement security solutions that can detect and block malicious attachments. References:
