 File Search and Destroy is a feature of Cortex XDR that allows you to search for and remove malicious files from endpoints. You can use this feature to find files by their hash, full path, or partial path using regex parameters. You can then select the files from the search results and destroy them by hash or by path. When you destroy a file by hash, all the file instances on the endpoint are removed. File Search and Destroy is useful for quickly responding to threats and preventing further damage. References:

The difference between presets and datasets in XQL is that a dataset is a built-in or third-party data source, while a preset is a group of XDR data fields. A dataset is a collection of data that you can query and analyze using XQL. A dataset can be a Cortex data lake data source, such as endpoints, alerts, incidents, or network flows, or a third-party data source, such as AWS CloudTrail, Azure Activity Logs, or Google Cloud Audit Logs. A preset is a predefined set of XDR data fields that are relevant for a specific use case, such as process execution, file operations, or network activity. A preset can help you simplify and standardize your XQL queries by selecting the most important fields for your analysis. You can use presets with any Cortex data lake data source, but not with third-party data sources. References:

 UASLR stands for User Address Space Layout Randomization, which is a feature of Exploit Prevention Module (EPM) that provides better entropy for randomization of memory locations. UASLR adds entropy to the base address of the executable image and the heap, making it harder for attackers to predict the memory layout of a process. UASLR is enabled by default for all processes, but can be disabled or customized for specific applications using the EPM policy settings. References:

 A logical schema in an XQL query is a field, which is a named attribute of a dataset. A field can have a data type, such as string, integer, boolean, or array. A field can also have a modifier, such as bin or expand, that transforms the field value in the query output. A field can be used in the select, where, group by, order by, or having clauses of an XQL query. References:

The Agent Auto Upgrade widget shows the status of the agent auto upgrade feature on the endpoints. The widget displays the number of agents that are up to date, in progress, pending, failed, and not configured. In this case, the widget shows that there are 450 agents that are up to date, 78 in progress, 15 pending, 18 failed, and 128 not configured. This means that the agent auto upgrade feature was enabled but not on all endpoints. References:
