5V0-93.22 Exam Dumps - VMware Carbon Black Cloud Endpoint Standard Skills

The tool that the security administrator is using to remediate a security vulnerability that may affect the sensors is Live Response. Live Response is a feature of VMware Carbon Black Cloud Endpoint Standard that allows the administrator to perform remote investigations, contain ongoing attacks, and remediate threats using a command line interface. Live Response enables the administrator to interact with the sensors and access the endpoints in real time, using various commands and scripts. Live Response can also be used to upload or download files, execute processes, terminate processes, delete files, and more12.

The other tools are not relevant or applicable for this scenario. CBLauncher is a tool that allows the administrator to launch applications on the endpoint without triggering policy rules or alerts. CBLauncher is useful for troubleshooting application compatibility issues or testing new applications, but it does not provide interaction or remote access for further investigation3. PowerCLI is a tool that allows the administrator to automate and manage VMware products and services using PowerShell commands and scripts. PowerCLI is useful for administering VMware virtual machines, hosts, networks, storage, and more, but it does not provide interaction or remote access for further investigation4. IRepCLI is a tool that allows the administrator to generate and upload reputation information for files on the endpoint. IRepCLI is useful for enhancing the threat intelligence and detection capabilities of VMware Carbon Black Cloud, but it does not provide interaction or remote access for further investigation5. References:

The impact of using the wildcards in the path is that all executable files in the “Program Files” folder and subfolders will be ignored, including malware files. This is because the double asterisk ** matches any files or directories in that path, and the Bypass action means that the sensor will notmonitor or block any operations performed by those files. This is a very permissive and risky rule, as it could allow malicious files to run without interference from the sensor. A more restrictive and secure rule would be to specify the exact path of the application that needs to be allowed, and use the Allow and Log action instead of Bypass. This way, the sensor will only ignore the specified application, and still log its operations for visibility and analysis. References: Carbon Black Cloud: How to Use Wildcards in Policy Rules, Set Permission Policy Rules

The impact of using the wildcards in the path for this rule is C. Any executable in the downloads directory for any user on the system will be bypassed for inspection. This is because the permission rule has the following options selected:

• Application at path: C:\Users*\Downloads**
• Operation Attempt: Performs any operation
• Action: Bypass

The application at path field specifies the path of the executable file that the rule applies to. The * wildcard matches 0 or more consecutive characters up to a single subdirectory level. For example, C:\Users*\ matches any subdirectory under the Users directory, such as C:\Users\Lorie, C:\Users\John, or C:\Users\Alice. The ** wildcard matches a partial path across all subdirectory levels and is recursive. For example, \Downloads** matches any files in that directory and all subdirectories. Therefore, by using the wildcards in the application at path field, the permission rule covers any executable file in the downloads directory for any user on the system.

The operation attempt field specifies the type of operation that the executable file attempts to perform. The Performs any operation option means that the rule applies to any operation, such as creating a file, modifying a registry key, or executing a command.

The action field specifies the action that the VMware Carbon Black Cloud Endpoint Standard sensor takes when the rule is triggered. The Bypass option means that the sensor ignores the executable file and does not apply any blocking rules or log any events for it1.

Therefore, by using the wildcards in the path for this rule, the permission rule effectively bypasses any executable file in the downloads directory for any user on the system from the VMware Carbon Black Cloud Endpoint Standard sensor’s prevention and detection capabilities. References:

The best rule to prevent a spreadsheet from being misused to run malicious code, while minimizing the risk of breaking normal operations of a spreadsheet, is B. **\excel.exe [Invokes a command interpreter] [Deny operation]. This rule will prevent any Excel process from invoking a command interpreter, such as cmd.exe or powershell.exe, which is a common technique used by malware to execute malicious commands or scripts. This rule will deny the operation but not terminate the process, which may allow the spreadsheet to continue functioning normally. This rule is more specific and effective than option A, which only applies to Microsoft Office applications that run external code, or option C, which applies to Excel applications that communicate over the network. Option D is incorrect because it is too vague and may not catch all the possible ways that a spreadsheet can run malware.

VMware Carbon Black Cloud Endpoint Standard uses a hybrid approach to determine the reputation of files on the endpoints. It combines local scan, which uses signature-based detection to identify known malware, and cloud scan, which uses cloud-based analytics and machine learning to identify unknown or emerging threats. When a sensor’s local AV signatures are out-of-date, it means that the local scan cannot detect the latest malware variants that have been added to the signature database. However, this does not affect the cloud scan, which can still determine the reputation of newly discovered files based on their behavior, characteristics, and context. Therefore, the effect of having out-of-date local AV signatures is that the reputation is determined by cloud reputation, which is more accurate and up-to-date than signature-based detection. The other options are not correct, because the sensor does not prompt the end user, automatically block, or fail to block a new file based on the local AV signatures alone. References: Carbon Black Cloud Endpoint Standard - Technical Overview, View and Update Signature Versions, Endpoint Standard: How to verify AV Signatures are updating
