質問 # 41
Which built-in dashboard would be the best option for an executive, if they were looking for the Mean Time to Resolution (MTTR) metric?
正解：C
解説：
The Incident Management Dashboard provides a high-level overview of the incident response process, including the Mean Time to Resolution (MTTR) metric. This metric measures the average time it takes to resolve an incident from the moment it is created to the moment it is closed. The dashboard also shows the number of incidents by status, severity, and assigned analyst, as well as the top alerts by category, source, and destination. The Incident Management Dashboard is designed for executives and managers who want to monitor the performance and efficiency of their security teams. Reference: [PCDRA Study Guide], page 18.

When viewing the incident directly, what is the "assigned to" field value of a new Incident that was just reported to Cortex?
正解：D
解説：
The "assigned to" field value of a new incident that was just reported to Cortex is "Unassigned". This means that the incident has not been assigned to any analyst or group yet, and it is waiting for someone to take ownership of it. The "assigned to" field is one of the default fields that are displayed in the incident layout, and it can be used to filter and sort incidents in the incident list. The "assigned to" field can be changed manually by an analyst, or automatically by a playbook or a rule12.
Let's briefly discuss the other options to provide a comprehensive explanation:
A . Pending: This is not the correct answer. Pending is not a valid value for the "assigned to" field. Pending is a possible value for the "status" field, which indicates the current state of the incident. The status field can have values such as "New", "Active", "Done", "Closed", or "Pending"3.
B . It is blank: This is not the correct answer. The "assigned to" field is never blank for any incident. It always has a default value of "Unassigned" for new incidents, unless a playbook or a rule assigns it to a specific analyst or group12.
D . New: This is not the correct answer. New is not a valid value for the "assigned to" field. New is a possible value for the "status" field, which indicates the current state of the incident. The status field can have values such as "New", "Active", "Done", "Closed", or "Pending"3.
In conclusion, the "assigned to" field value of a new incident that was just reported to Cortex is "Unassigned". This field can be used to manage the ownership and responsibility of incidents, and it can be changed manually or automatically.

質問 # 43
What is by far the most common tactic used by ransomware to shut down a victim's operation?
正解：A
解説：
Ransomware is a type of malicious software, or malware, that encrypts certain files or data on the victim's system or network and prevents them from accessing their data until they pay a ransom. This is by far the most common tactic used by ransomware to shut down a victim's operation, as it can cause costly disruptions, data loss, and reputational damage. Ransomware can affect individual users, businesses, and organizations of all kinds. Ransomware can spread through various methods, such as phishing emails, malicious attachments, compromised websites, or network vulnerabilities. Some ransomware variants can also self-propagate and infect other devices or networks. Ransomware authors typically demand payment in cryptocurrency or other untraceable methods, and may threaten to delete or expose the encrypted data if the ransom is not paid within a certain time frame. However, paying the ransom does not guarantee that the files will be decrypted or that the attackers will not target the victim again. Therefore, the best way to protect against ransomware is to prevent infection in the first place, and to have a backup of the data in case of an attack1234 Reference:

質問 # 44
An attacker tries to load dynamic libraries on macOS from an unsecure location. Which Cortex XDR module can prevent this attack?
正解：C
解説：
The correct answer is D. Dylib Hijacking. Dylib Hijacking, also known as Dynamic Library Hijacking, is a technique used by attackers to load malicious dynamic libraries on macOS from an unsecure location. This technique takes advantage of the way macOS searches for dynamic libraries to load when an application is executed. To prevent such attacks, Palo Alto Networks offers the Dylib Hijacking prevention capability as part of their Cortex XDR platform. This capability is designed to detect and block attempts to load dynamic libraries from unauthorized or unsecure locations1.
Let's briefly discuss the other options to provide a comprehensive explanation:
A . DDL Security: This is not the correct answer. DDL Security is not specifically designed to prevent dynamic library loading attacks on macOS. DDL Security is focused on protecting against DLL (Dynamic Link Library) hijacking on Windows systems2.
B . Hot Patch Protection: Hot Patch Protection is not directly related to preventing dynamic library loading attacks. It is a security feature that protects against runtime patching or modification of code in memory, often used by advanced attackers to bypass security measures3. While Hot Patch Protection is a valuable security feature, it is not directly relevant to the scenario described.
C . Kernel Integrity Monitor (KIM): Kernel Integrity Monitor is also not the correct answer. KIM is a module in Cortex XDR that focuses on monitoring and protecting the integrity of the macOS kernel. It detects and prevents unauthorized modifications to critical kernel components4. While KIM plays an essential role in overall macOS security, it does not specifically address the prevention of dynamic library loading attacks.
In conclusion, Dylib Hijacking is the Cortex XDR module that specifically addresses the prevention of attackers loading dynamic libraries from unsecure locations on macOS. By leveraging this module, organizations can enhance their security posture and protect against this specific attack vector.

質問 # 45
When using the "File Search and Destroy" feature, which of the following search hash type is supported?
正解：D
解説：
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 and Destroy 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 Reference:
