NEW QUESTION # 56
Which Exploit ProtectionModule (EPM) can be used to prevent attacks based on OS function?
- A. UASLR
- B. Memory Limit Heap Spray Check
- C. DLL Security
- D. JIT Mitigation
Answer: D
Explanation:
Explanation
JIT Mitigation is an Exploit Protection Module (EPM) that can be used to prevent attacks based on OS function. JIT Mitigation protects against exploits that use the Just-In-Time (JIT) compiler of the OS to execute malicious code. JIT Mitigation monitors the memory pages that are allocated by the JIT compiler and blocks any attempts to execute code from those pages. This prevents attackers from using the JIT compiler as a way to bypass other security mechanisms such as Data Execution Prevention (DEP) and Address Space Layout Randomization (ASLR). References:

Which statement is true for Application Exploits and Kernel Exploits?
- A. The ultimate goal of any exploit is to reach the kernel.
- B. Application exploits leverage kernel vulnerability.
- C. The ultimate goal of any exploit is to reach the application.
- D. Kernel exploits are easier to prevent then application exploits.
Answer: A
Explanation:
Explanation
The ultimate goal of any exploit is to reach the kernel, which is the core component of the operating system that has the highest level of privileges and access to the hardware resources. Application exploits are attacks that target vulnerabilities in specific applications, such as web browsers, email clients, or office suites. Kernel exploits are attacks that target vulnerabilities in the kernel itself, such as memory corruption, privilege escalation, or code execution. Kernel exploits are more difficult to prevent and detect than application exploits, because they can bypass security mechanisms and hide their presence from the user and the system.

NEW QUESTION # 64
When creating a BIOC rule, which XQL query can be used?
- A. dataset = xdr_data
| filter event_type = PROCESS and
event_sub_type = PROCESS_START and
action_process_image_name ~= ".*?\.(?:pdf|docx)\.exe" - B. dataset = xdr_data
| filter action_process_image_name ~= ".*?\.(?:pdf|docx)\.exe"
| fields action_process_image - C. dataset = xdr_data
| filter event_behavior = true
event_sub_type = PROCESS_START and
action_process_image_name ~= ".*?\.(?:pdf|docx)\.exe" - D. dataset = xdr_data
| filter event_sub_type = PROCESS_START and
action_process_image_name ~= ".*?\.(?:pdf|docx)\.exe"
Answer: A
Explanation:
Explanation
A BIOC rule is a custom detection rule that uses the Cortex Query Language (XQL) to define the behavior or actions that indicate a potential threat. A BIOC rule can use the xdr_data and cloud_audit_log datasets and presets for these datasets. A BIOC rule can also use the filter stage, alter stage, and functions without any aggregations in the XQL query. The query must return a single field named action_process_image, which is the process image name of the suspicious process. The query must also include the event_type and event_sub_type fields in the filter stage to specify the type and sub-type of the event that triggers the rule.
Option B is the correct answer because it meets all the requirements for a valid BIOC rule query. It uses the xdr_data dataset, the filter stage, the event_type and event_sub_type fields, and the action_process_image_name field with a regular expression to match any process image name that ends with
.pdf.exe or .docx.exe, which are common indicators of malicious files.
Option A is incorrect because it does not include the event_type field in the filter stage, which is mandatory for a BIOC rule query.
Option C is incorrect because it does not include the event_type and event_sub_type fields in the filter stage, and it uses the fields stage, which is not supported for a BIOC rule query. It also returns the action_process_image field instead of the action_process_image_name field, which is the expected output for a BIOC rule query.
Option D is incorrect because it uses the event_behavior field, which is not supported for a BIOC rule query. It also does not include the event_type field in the filter stage, and it uses the event_sub_type field incorrectly.
The event_sub_type field should be equal to PROCESS_START, not true.

NEW QUESTION # 66
Which statement best describes how Behavioral Threat Protection (BTP) works?
- A. BTP runs on the Cortex XDR and distributes behavioral signatures to all agents.
- B. BTP matches EDR data with rules provided by Cortex XDR.
- C. BTP injects into known vulnerable processes to detect malicious activity.
- D. BTP uses machine Learning to recognize malicious activity even if it is not known.
Answer: D
Explanation:
Explanation
The statement that best describes how Behavioral Threat Protection (BTP) works is D, BTP uses machine learning to recognize malicious activity even if it is not known. BTP is a feature of Cortex XDR that allows you to define custom rules to detect and block malicious behaviors on endpoints. BTP uses machine learning to profile behavior and detect anomalies indicative of attack. BTP can recognize malicious activity based on file attributes, registry keys, processes, network connections, and other criteria, even if the activity is not associated with any known malware or threat. BTP rules are updated through content updates and can be managed from the Cortex XDR console.
The other statements are incorrect for the following reasons:
* A is incorrect because BTP does not inject into known vulnerable processes to detect malicious activity.
BTP does not rely on process injection, which is a technique used by some malware to hide or execute code within another process. BTP monitors the behavior of all processes on the endpoint, regardless of their vulnerability status, and compares them with the BTP rules.
* B is incorrect because BTP does not run on the Cortex XDR and distribute behavioral signatures to all agents. BTP runs on the Cortex XDR agent, which is installed on the endpoint, and analyzes the endpoint data locally. BTP does not use behavioral signatures, which are predefined patterns of malicious behavior, but rather uses machine learning to identify anomalies and deviations from normal behavior.
* C is incorrect because BTP does not match EDR data with rules provided by Cortex XDR. BTP is part of the EDR (Endpoint Detection and Response) capabilities of Cortex XDR, and uses the EDR data collected by the Cortex XDR agent to perform behavioral analysis. BTP does not match the EDR data with rules provided by Cortex XDR, but rather applies the BTP rules defined by the Cortex XDR administrator or the Palo Alto Networks threat research team.

NEW QUESTION # 67
When using the "File Search and Destroy" feature, which of the following search hash type is supported?
- A. SHA256 hash of the file
- B. AES256 hash of the file
- C. SHA1 hash of the file
- D. MD5 hash of the file
Answer: A
Explanation:
Explanation
The File Search and Destroy feature is a capability of Cortex XDR that allows you to search for and delete malicious or unwanted files across your endpoints. You can use this feature to quickly respond to incidents, remediate threats, and enforce compliance policies. To use the File Search andDestroy feature, you need to specify the file name and the file hash of the file you want to search for and delete. The file hash is a unique identifier of the file that is generated by a cryptographic hash function. The file hash ensures that you are targeting the exact file you want, and not a file with a similar name or a different version. The File Search and Destroy feature supports the SHA256 hash type, which is a secure hash algorithm that produces a 256-bit (32-byte) hash value. The SHA256 hash type is widely used for file integrity verification and digital signatures. The File Search and Destroy feature does not support other hash types, such as AES256, MD5, or SHA1, which are either encryption algorithms or less secure hash algorithms. Therefore, the correct answer is A, SHA256 hash of the file1234 References:

- D. Exfiltration, Command and Control, Collection
Answer: C
Explanation:
Explanation
Cortex XDR Analytics is a feature of Cortex XDR that leverages machine learning and behavioral analytics to detect and alert on malicious activity across the network and endpoint layers. Cortex XDR Analytics can alert when detecting activity matching the following MITRE ATT&CKTM techniques: Exfiltration, Command and Control, Lateral Movement, Execution, Persistence, Privilege Escalation, Defense Evasion, Credential Access, Discovery, and Collection. However, among the options given in the question, the correct answer is D, Exfiltration, Command and Control, Lateral Movement. These are three of the most critical techniques that indicate an advanced and persistent threat (APT) in the environment. Exfiltration refers to the technique of transferring data or information from the compromised system or network to an external location controlled by the adversary. Command and Control refers to the technique of communicating with the compromised system or network to provide instructions, receive data, or update malware. Lateral Movement refers to the technique of moving from one system or network to another within the same environment, usually to gain access to more resources or data. Cortex XDR Analytics can alert on these techniques by analyzing various data sources, such as network traffic, firewall logs, endpoint events, and threat intelligence, and applying behavioral models, anomaly detection, and correlation rules. Cortex XDR Analytics can also map the alerts to the corresponding MITRE ATT&CKTM techniques and provide additional context and visibility into the attack chain1234 References:

When reaching out to TAC for additional technical support related to a Security Event; what are two critical pieces of information you need to collect from the Agent? (Choose Two)
- A. The prevention archive from the alert.
- B. The unique agent id.
- C. The agent technical support file.
- D. A list of all the current exceptions applied to the agent.
- E. The distribution id of the agent.
Answer: A,C
Explanation:
Explanation
When reaching out to TAC for additional technical support related to a security event, two critical pieces of information you need to collect from the agent are:
* The agent technical support file. This is a file that contains diagnostic information about the agent, such as its configuration, status, logs, and system information. The agent technical support file can help TAC troubleshoot and resolve issues with the agent or the endpoint. You can generate and download the agent technical support file from the Cortex XDR console, or from the agent itself.
* The prevention archive from the alert. This is a file that contains forensic data related to the alert, such as the process tree, the network activity, the registry changes, and the files involved. The prevention archive can help TAC analyze and understand the alert and the malicious activity. You can generate and
* download the prevention archive from the Cortex XDR console, or from the agent itself.
The other options are not critical pieces of information for TAC, and may not be available or relevant for every security event. For example:
* The distribution id of the agent is a unique identifier that is assigned to the agent when it is installed on the endpoint. The distribution id can help TAC identify the agent and its profile, but it is not sufficient to provide technical support or forensic analysis. The distribution id can be found in the Cortex XDR console, or in the agent installation folder.
* A list of all the current exceptions applied to the agent is a set of rules that define the files, processes, or behaviors that are excluded from the agent's security policies. The exceptions can help TAC understand the agent's configuration and behavior, but they are not essential to provide technical support or forensic analysis. The exceptions can be found in the Cortex XDR console, or in the agent configuration file.
* The unique agent id is a unique identifier that is assigned to the agent when it registers with Cortex XDR. The unique agent id can help TAC identify the agent and its endpoint, but it is not sufficient to provide technical support or forensic analysis. The unique agent id can be found in the Cortex XDR console, or in the agent log file.
