Query across all entities

Query across all entities with Legacy Query Builder in Cortex AgentiX.

---

Use the Query Builder to search hosts and processes across file, network, registry, and process events. You can also search Windows event logs and Linux system authentication logs.

For example, you can search for:

• All activity on a host.
• All activity initiated by a process on a host.

How to build a query

1. From Cortex AgentiX, select Investigation & Response → Search → Query Builder.
2. Select ALL ACTIONS.
3. Optional: Limit the scope to a specific acting process.

   Select Add Process. Then specify one or more attributes for the acting parent process.

   Use a pipe (|) to separate values. Use an asterisk (*) to match any characters.

   • SIGNATURE: Parent process signing status.
   • SIGNER: Entity that signed the parent process certificate.
   • PID: Parent process ID.
   • Run search on process, Causality and OS actors: Applies the criteria to initiating processes. Clear this option to configure different attributes.

   • HOST: HOST NAME, HOST IP address, HOST OS, HOST ADDRESS, or INSTALLATION TYPE.
   • INSTALLATION TYPE: Agent or data collector.
   • PROCESS: NAME, PATH, CMD, MD5, SHA256, USER NAME, SIGNATURE, or PID.

   Use a pipe (|) to separate values. Use an asterisk (*) to match any characters.
5. Specify the event time period.

   Select Last 24H, Last 7D, Last 1M, or Custom.
